(print/R-knitr) Updated 1.33 to 1.34

(https://github.com/yihui/knitr/releases)
@yihui yihui released this Sep 9, 2021

NEW FEATURES

  * Added a package option latex.tilde so that users can customize the tilde
    symbol, e.g., you can set knitr::opts_knit$set(latex.tilde = "\\hlopt{\\
    scriptsize{\\ensuremath{\\sim}}}"). This is because the default tilde is
    too high in the PDF output, and it's often more desirable to use a middle
    tilde instead (thanks, @brry #1992, @jaredlander #492).

  * For the tikz engine, the class options of the standalone document classs
    can be specified via the chunk option engine.opts$classoption (thanks,
    @XiangyunHuang, #1985). The default value is tikz, i.e., \documentclass
    [tikz]{standalone} is used by default.

  * Added the ability to pass additional arguments to dvisvgm when using the
    tikz engine with fig.ext = "svg" by using dvisvgm.opts in engine.opts
    (thanks, @andrewheiss, #2039). Recent versions of dvisvgm now allow you to
    embed fonts into SVG files as base64-encoded WOFF files, so tikz chunks can
    embed fonts using like so: ```{tikz, fig.ext="svg", engine.opts=list
    (dvisvgm.opts = "--font-format=woff")}.

  * Added a new targets engine (ropensci/targets#503, @wlandau). Details:
    https://books.ropensci.org/targets/markdown.html.

  * The chunk option cache.globals can take values TRUE and FALSE now (in
    addition to a character vector). When FALSE, it tries to find all symbols
    in the code chunk, no matter if they are local or global variables. When
    NULL or TRUE, it tries to find all global variables (thanks, @knokknok, #
    1898).

MAJOR CHANGES

  * An error is now thrown when an inline code result is not coercible to
    character. This has always been the assumed behavior but it happens to be
    different in certain formats with unknown automatic coercion. This is now
    enforced to prevent any unexpected output. An inline code expression must
    evaluate to a character vector or an object coercible by as.character() (#
    2006).

  * The markdown package has been moved from Imports to Suggests in knitr's
    DESCRIPTION, which means it is no longer a hard dependency but has become a
    soft dependency of knitr (#1864). One consequence for package developers is
    that if you use the vignette engines based on markdown (such as
    knitr::knitr), you will have to explicitly declare the (soft) dependency on
    markdown, because the implicit dependency through knitr is no longer there.

  * For R packages that use the knitr::rmarkdown engine to build their
    vignettes, rmarkdown must be declared as a dependency in the package
    DESCRIPTION (e.g., in Suggests). Previously, knitr would fall back to using
    the markdown package to build vignettes if rmarkdown is not declared (#1864
    , #2020).

  * write_bib() only uses the first URL if multiple are found in a package (#
    2028).

MINOR CHANGES

  * The attribute data-external="1" will be added to <iframe>s \ 
generated by
    include_url() to prevent Pandoc from embedding the URL as base64 data
    (thanks, @IndrajeetPatil, https://stackoverflow.com/q/67477667/559676).

  * The chunk option strip.white = TRUE used to work only when the chunk option
    collapse = FALSE. Now the two options are independent, i.e., strip.white
    also works when collapse = TRUE (thanks, @kbvernon, #2011).

  * When building R Markdown vignettes but Pandoc is not available, the
    vignette engine will emit a message instead of a warning before falling
    back to using the markdown package.

  * The internal function is_abs_path() has been removed. Users (if any) should
    use the exported function xfun::is_abs_path() instead.

BUG FIXES

  * Fix an issue with the RStudio IDE when using knitr::include_url() or
    knitr::include_app() in interactive Notebook mode. This will no more cause
    an error but print the list object as is (thanks, @systemnova, #2015).

  * Fix a regression with fig.keep chunk option used in chunks with only one
    figure where the figure was not showing in output (thanks, @fmichonneau, #
    1993).

  * Allow vignettes to be tangled (and output compared) in R CMD check if they
    have a corresponding .Rout.save (thanks, @lentinj, #2018).

(print/R-knitr) Update TEST_DEPENDS+= info, not compelete yet

Log message:
(print/R-knitr) Updated 1.23 to 1.33, NEWS.md unknown

Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the
following:

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

[1] http://mail-index.netbsd.org/tech-pkg/2019/08/02/msg021711.html

Log message:
Remove MASTER_SITES= from individual R package Makefiles.

Each R package should include ../../math/R/Makefile.extension, which also
defines MASTER_SITES.  Consequently, it is redundant for the individual
packages to do the same.  Package-specific definitions also prevent
redefining MASTER_SITES in a single common place.

CHANGES IN knitr VERSION 1.15.1

@yihui yihui released this on 23 Nov 2016 · 49 commits to master since this \ 
release
NEW FEATURES

    added a new hook function hook_pngquant() that can call pngquant to optimize \ 
PNG images (thanks, @slowkow, #1320)

BUG FIXES

    not really a knitr bug, but knit_params() should be better at dealing with \ 
multibyte characters now due to the bug fix in the yaml package viking/r-yaml#6

CHANGES IN knitr VERSION 1.15

@yihui yihui released this on 10 Nov 2016 · 63 commits to master since this \ 
release
NEW FEATURES

    NA values can be displayed using different characters (including empty \ 
strings) in kable(); you can set the option knitr.kable.NA, e.g. \ 
options(knitr.kable.NA = '') to hide NA values (#1283)
    added a fortran95 engine (thanks, @stefanedwards, #1282)
    added a block2 engine for R Markdown documents as an alternative to the \ 
block engine; it should be faster and supports arbitrary Pandoc's Markdown \ 
syntax, but it is essentially a hack; note when the output format is LaTeX/PDF, \ 
you have to define \let\BeginKnitrBlock\begin \let\EndKnitrBlock\end in the \ 
LaTeX preamble
    figure captions specified in the chunk option fig.cap are also applied to \ 
HTML widgets (thanks, @byzheng, rstudio/bookdown#118)
    when the chunk option fig.show = 'animate' and ffmpeg.format = 'gif', a GIF \ 
animation of the plots in the chunk will be generated for HTML output \ 
(https://twitter.com/thomasp85/status/785800003436421120)
    added a width argument to write_bib() so long lines in bib entries can be wrapped
    the inline syntax r#code is also supported besides r code; this can make \ 
sure the inline expression is not split when the line is wrapped (thanks, Dave \ 
Jarvis)
    provided a global R option knitr.use.cwd so users can choose to evaluate the \ 
R code chunks in the current working directory after setting \ 
options(knitr.use.cwd = TRUE); the default is to evaluate code in the directory \ 
of the input document, unless the knitr option opts_knit$set(root.dir = ...) has \ 
been set
    if options(knitr.digits.signif = TRUE), numbers from inline expressions will \ 
be formatted using getOption('digits') as the number of significant digits, \ 
otherwise (the default behavior) getOption('digits') is treated as the number of \ 
decimal places (thanks, @numatt, #1053)
    the chunk option engine.path can also be a list of paths to the engine \ 
executables now, e.g., you can set knitr::opts_chunk$set(engine.path = \ 
list(python = '/anaconda/bin/python', perl = '/usr/local/bin/perl')), then when \ 
a python code chunk is executed, /anaconda/bin/python will be called instead of \ 
the system default (rstudio/rmarkdown#812)
    introduced a mechanism to protect text output in the sense that it will not \ 
be touched by Pandoc during the conversion from R Markdown to another format; \ 
this is primarily for package developers to extend R Markdown; see ?raw_output \ 
for details (which also shows new functions extract_raw_output() and \ 
restore_raw_output())

MAJOR CHANGES

    the minimal version of R required for knitr is 3.1.0 now (#1269)
    the formatR package is an optional package since the default chunk option \ 
tidy = FALSE has been there for a long time; if you use tidy = TRUE, you need to \ 
install formatR separately if it is not installed
    :set +m is no longer automatically added to haskell code chunks (#1274)

MINOR CHANGES

    the package option opts_knit$get('stop_on_error') has been removed
    the confusing warning message about knitr::knit2html() when buiding package \ 
vignettes using the knitr::rmarkdown engine without pandoc/pandoc-citeproc has \ 
been removed (#1286)
    the default value of the quiet argument of plot_crop() was changed from \ 
!opts_knit$get('progress') to TRUE, i.e., by default the messages from cropping \ 
images are suppressed

BUG FIXES

    the chunk option cache.vars did not really behave like what was documented \ 
(thanks, @simonkth, #1280)
    asis_output() should not be merged with normal character output when \ 
results='hold' (thanks, @kevinushey, #1310)

CHANGES IN knitr VERSION 1.14

@yihui yihui released this on 12 Aug 2016 · 845 commits to master since this \ 
release
NEW FEATURES

    improved caching for Rcpp code chunks: the shared library built from the C++ \ 
code will be preserved on disk and reloaded the next time if caching is enabled \ 
(chunk option cache = TRUE), so that the exported R functions are still usable \ 
in later R code chunks; note this feature requires Rcpp >= 0.12.5.6 (thanks, \ 
@jjallaire, #1239)
    added a helper function all_rcpp_labels(), which is simply all_labels(engine \ 
== 'Rcpp') and can be used to extract all chunk lables of Rcpp chunks
    added a new engine named sql that uses the DBI package to execute SQL \ 
queries, and optionally assign the result to a variable in the knitr session; \ 
see http://rmarkdown.rstudio.com/authoring_knitr_engines.html for details \ 
(#1241)
    fig.keep now accepts numeric values to index low-level plots to keep (#1265)

BUG FIXES

    fixed #1211: pandoc('foo.md') generates foo_utf8.html instead of foo.html by \ 
default
    fixed #1236: include = FALSE for code chunks inside blockquotes did not work \ 
(should return > instead of a blank line) (thanks, @fmichonneau)
    fixed #1217: define the command \hlipl for syntax highlighting for Rnw \ 
documents (thanks, @conjugateprior)
    fixed #1215: restoring par() settings might fail when the plot window is \ 
partitioned, e.g. par(mfrow = c(1, 2)) (thanks, @jrwishart @jmichaelgilbert)
    fixed #1250: in the quiet mode, knit() should not emit the message \ 
"processing file ..." when processing child documents (thanks, \ 
@KZARCA)

MAJOR CHANGES

    knitr will no longer generate screenshots automatically for HTML widgets if \ 
the webshot package or PhantomJS is not installed

MINOR CHANGES

    if dev = 'cairo_pdf', the cairo_pdf device will be used to record plots \ 
(previously the pdf device was used) (#1235)
    LaTeX short captions now go up to the first ., : or ; character followed by \ 
a space or newline (thanks, @knokknok, #1249)

CHANGES IN knitr VERSION 1.13

NEW FEATURES

    code chunks that generate metadata may be cached now; it requires \ 
htmlwidgets >= v0.6 and htmltools >= 0.3.3 if you cache code chunks that \ 
contain HTML widgets or Shiny inputs/outputs (#1158)

    when the output format is not HTML, HTML widgets used to fail to render; now \ 
knitr will try to generate static screenshots for HTML widgets automatically \ 
using the webshot package; you can specify alternative screenshots via the chunk \ 
option screenshot.alt (which takes a character vector of image paths), and pass \ 
more options to webshot::webshot() via the chunk option screenshot.opts, e.g. \ 
list(delay = 3, cliprect = 'viewport')

    added two functions include_url() and include_app() to embed URLs in the \ 
output (the latter is for Shiny app URLs); when the output format is HTML, \ 
iframe will be used; otherwise screenshots of the URLs will be used

    screenshotting for HTML widgets and URLs can be forced for all output \ 
formats via the chunk option screenshot.force = TRUE; if you set the chunk \ 
option screenshot.force = FALSE, knitr will just render these content normally \ 
and not take screenshots

    added a new chunk option fig.link, which can be used to attach hyperlinks on \ 
figures, e.g. you can add a link to a screenshot of a Shiny app so that readers \ 
can check out the actual live app after clicking on the static screenshot (this \ 
chunk option currently only works for Markdown and LaTeX output)

    syntactical errors in code chunks will be allowed when the chunk option \ 
error = TRUE and the package version of evaluate is at least 0.8.4; previously \ 
knitr would just stop on parsing errors (hadley/evaluate#65)

    PNG/JPEG images included via include_graphics() also respects the chunk \ 
option dpi now; if it is numeric and the chunk option out.width is not set, the \ 
output width (in inches) of an image will be automatically calculated from the \ 
actual width (in pixels) divided by dpi; note this feature requires the packages \ 
png and/or jpeg to be installed, and you can disable the feature using dpi = NA \ 
(thanks, @hadley, rstudio/bookdown#38)

    added a new hook function named evaluate in knit_hooks so that users can \ 
redefine a evaluator to evaluate the code chunk; the default is \ 
evaluate::evaluate(), and your custom evaluator must be compatible with \ 
evaluate::evaluate() in terms of the argument names and the data structure of \ 
the returned value (a list of values with special classes)

    added a new function combine_words() to combine multiple words / phrases \ 
into a single string, which may be useful in inline R expressions, e.g. \ 
combine_words(c('a', 'b', 'c')) returns a, b, and c

    render_markdown() gained a new argument fence_char to customize the \ 
character to be used as the code blocks fence, e.g. it can be a backtick, or a \ 
tilde, depending on the Markdown rendering engine (thanks, @tinyheero, #1161)

    the pandoc() function no longer assumes Markdown input (thanks, @scls19fr, #1170)

    added a new function knit_meta_add() so that users can manually inject \ 
metadata into the current knitr session

    for the tikz engine, if fig.ext = 'svg', dvisvgm will be called to convert \ 
the DVI output of TikZ to SVG; you need to install dvisvgm, and Windows users \ 
have to install GhostScript as well (thanks, @dkilfoyle, #1177)

    new js and css engines which surround their content with <script> and \ 
<style> tags respecitvely, and print no output when not in an HTML \ 
document

    for LaTeX tables, kable() supports short captions now via the caption.short \ 
argument, e.g. kable(..., caption = 'A long caption', caption.short = 'A short \ 
caption') (thanks, @ismayc, #1199)

    added three global R options knitr.sanitize.errors, knitr.sanitize.warnings, \ 
and knitr.sanitize.messages to mask or change the messages, e.g. if \ 
options(knitr.sanitize.errors = TRUE) and the chunk option error = TRUE, the \ 
actual error message will be replaced by a character string like "An error \ 
occurred"; these options can also accept character values so you can \ 
customize the messages to be displayed, e.g. options(knitr.sanitize.warnings = \ 
'You had a warning from the code'); see rstudio/shiny#1123 for the motivation of \ 
these options

BUG FIXES

    when the chunk option cache.rebuild = TRUE, the cache database should be \ 
rewritten (thanks, Oleg Mayba)

    include_graphics() did not work in inline R expressions (thanks, @WastlM, #1166)

    the cex parameter was not correctly restored in the case of \ 
opts_knit$set(global.par = TRUE) (http://stackoverflow.com/q/35606445/559676)

    for Rnw documents, when there are two instances of \documentclass{}, knitr \ 
might mistakenly treats the second instance as the the actual command to declare \ 
the document class (thanks, #1180, @ekstroem)

    corrected the environment for evaluating R scripts in stitch_rhtml() and \ 
stitch_rmd() (thanks, @Hughan, #1207)

MAJOR CHANGES

    the default value of the package option eval.after is changed from NULL to \ 
fig.cap, i.e. the figure caption will always be evaluated after a code chunk is \ 
evaluated (thanks, @JoshOBrien, #1165)

    the function eclipse_theme() has been removed since the website \ 
eclipsecolorthemes.org has been down for a long time
