./math/R-zoo, S3 infrastructure for regular and irregular time series

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.8.6, Package name: R-zoo-1.8.6, Maintainer: pkgsrc-users

An S3 class with methods for totally ordered indexed observations. It
is particularly aimed at irregular time series of numeric
vectors/matrices and factors. Zoo's key design goals are independence
of a particular index/date/time class and consistency with ts and base
R by providing methods to extend standard generics.

Log message:
Update all R packages to canonical form.

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

- 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.

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.

math/R-zoo: Update to 1.8.1


  o New .DollarNames method (contributed by Josh Ulrich) to enable tab
    completion when using zoo_object$...

  o New default method for zoo::as.Date() that simply dispatches to

  o rollapply(x, k, FUN, align = "right") lead to an error if \ 
length(x) < k.
    This has been corrected to match the behavior of the other align types.

  o rollmean(), rollsum(), rollmedian(), and rollmax() no longer throw an
    error if the series is shorter than the window size. Instead rollapply()
    is called which either returns an empty series (if "fill" is not \ 
    or a padded series (if "fill" is specified, e.g., to NA).

  o read.zoo() now also handles "tbl" objects by coercing them to proper
    "data.frame"s first. Also gained a read = read.table argument to \ 
    convenience interfaces read.csv.zoo() etc.

  o The fortify() method gained a "names" argument so that the column names
    of the (melted) series can be modified.

Changes in Version 1.8-0

  o zoo() and zooreg() gained a calendar = getOption("zoo.calendar", TRUE)
    argument so that, by default, yearqtr and yearmon are used as the time
    index for regular zoo series with frequency 4 and 12, respectively. With
    calendar = FALSE the behavior from previous versions with plain
    unclassed time indexes can be obtained. Set options(zoo.calendar = FALSE)
    to always retain the old behavior.

  o na.locf() is made faster by using a diff()-based solution rather than
    cumsum() (suggested by Ruben Arslan). Also, the workhorse function
    na.locf0() underlying the default na.locf() method is now exported
    in the user interface as it is faster (but also supports less options).

  o Better support of vector-valued 'split' arguments in read.zoo().

  o Special-cased rollmax(..., k = 1) to return the input coredata().

  o as.character() for "yearqtr" objects did not process NA elements \

Log message:
Update to 1.7.14

Upstream changes:
Changes in Version 1.7-14

  o Several convenience interfaces to read.zoo() have been added:
    read.table.zoo(), read.csv.zoo(), read.csv2.zoo(), read.delim.zoo(),
    read.delim2.zoo(). All of these first call the corresponding read.*()
    function to read the data from a text file (with the respective default
    settings) and subsequently call read.zoo() to turn the data into
    a zoo series.

  o na.approx.default() did not properly process the "maxgap" argument
    if y did not contain any NAs but NAs were only created implicitly
    by xout being different from x (pointed out by Stefan Metzger).
    A suitable fix has been added that merges x and xout first.

  o aggregate.zoo() and rollapply.zoo() gained the argument coredata=TRUE
    which can control whether only the coredata is passed to each subset
    (previous behavior) or the full zoo series.

  o The "its" package has been archived on CRAN and hence removed from
    the list of zoo's suggested packages. However, various methods for
    objects of class "its" continue to be available in zoo in case someone
    still uses the legacy code.

Log message:
Update to 1.7.13

Upstream changes:
Changes in Version 1.7-13

  o The window() method erroneously dropped the dimension in case of
    1-column zoo series. Fixed now.

  o Bug fix in NA handling of rollmax() pointed out by Cory Fletcher.

  o A few as.yearmon/as.yearqtr methods were not registered in
    the NAMESPACE but are now.

  o If there are less then two non-NAs in na.approx() then approx()
    cannot be applied. Instead of throwing an error (as up to version
    1.7-12) simply no NAs are replaced now.

  o Bug fix for lag(z, k = k, na.pad = TRUE) which ignored na.pad = TRUE
    if 'k' was a vector of lags.
