# development  openxlsx 4.2.4

## Fixes

* `Write.xlsx()` now successfully passes `withFilter`
  ([#151](https://github.com/ycphs/openxlsx/issues/151))
* code clean up PR [#168](https://github.com/ycphs/openxlsx/pull/168)
* removal of unused variables PR
  [#168](https://github.com/ycphs/openxlsx/pull/168)

## New features

* adds `buildWorkbook()` to generate a `Workbook` object from a
  (named) list or a data.frame
  ([#192](https://github.com/ycphs/openxlsx/issues/192),
  [#187](https://github.com/ycphs/openxlsx/issues/187))
  * this is now recommended rather than the `write.xlsx(x, file) ; wb
    <- read.xlsx(file)` functionality before
  * `write.xlsx()` is now a wrapper for `wb <- buildWorkbook(x);
    saveWorkbook(x, file)`
  * parameter checking from `write.xlsx()` >> `buildWorkbook()` are
    now held off until passed to `writeData()`, `writeDataTable()`,
    etc
  * `row.names` is now deprecated for `writeData()` and
    `writeDataTable()`; please use `rowNames` instead
* `read.xlsx()` now checks for the file extension `.xlsx`; previously
  it would throw an error when the file was `.xls` or `.xlm` files

* memory allocation improvements
* global options added for `minWidth` and `maxWidth`

* `write.xlsx()` >> `buildWorkbook()` can now handle `colWidths`
  passed as either a single element or a `list()`

* Added ability to change positioning of summary columns and rows.
  * These can be set with the `summaryCol` and `summaryRow` arguments
    in `pageSetup()`.

* `activeSheet` allows to set and get the active (displayed) sheet of a worbook.

* Adds new global options for workbook formatting
  ([#165](https://github.com/ycphs/openxlsx/issues/165); see
  `?op.openxlsx`)

# openxlsx 4.2.3

## New Features

* Most of functions in openxlsx now support non-ASCII arguments
  better. More specifically, we can use non-ASCII strings as names or
  contents for `createNamedRegion()`
  ([#103](https://github.com/ycphs/openxlsx/issues/103)),
  `writeComment()`, `writeData()`, `writeDataTable()` and
  `writeFormula()`. In addition, openxlsx now reads comments and
  region names that contain non-ASCII strings correctly on
  Windows. Thanks to @shrektan for the PR
  [#118](https://github.com/ycphs/openxlsx/pull/118).

* `setColWidths()` now supports zero-length `cols`, which is
  convinient when `cols` is dynamically provided
  [#128](https://github.com/ycphs/openxlsx/issues/128). Thanks to
  @shrektan for the feature request and the PR.

## Fixes for Check issues

* Fix to pass the tests for link-time optimization type mismatches

* Fix to pass the checks of native code (C/C++) based on static code
  analysis

* Fix `loadWorkbook()` sometimes importing incorrect column attributes

# openxlsx 4.2.2

## New Features

* Added features for `conditionalFormatting` to support also 'contains
  not', 'begins with' and 'ends with'

  `returnValue` is `FALSE`
  ([#71](https://github.com/ycphs/openxlsx/issues/71))

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.
