R help - May 2019 - WriteXLS version 5.0.0 now available

Hi all,

I am pleased to announce that WriteXLS version 5.0.0 is now available on CRAN:

  https://cran.r-project.org/web/packages/WriteXLS/index.html

This supersedes version 4.1.0 and should appear on your local CRAN mirror in due
course, if not there already.

WriteXLS, first released in 2009, is a cross-platform, Perl-based R function to
create Excel 2003 (XLS) and Excel 2007 (XLSX) files from one or more data
frames.

The primary change in this major new version is improved support for
Unicode/UTF-8 variable width character sets, especially on Windows. This is
accomplished via the use of writeLines(..., useBytes = TRUE), rather than
write.table(), to create intermediate CSV files from the source R data frames.
These exported CSV files are then parsed by Perl scripts to create the resultant
Excel file.

The prior use of write.table() to create the CSV files could result in the
re-encoding of the content of the CSV files into the locale of the computer upon
which the code is running. This could result in the loss of the source character
encoding used in the originating R data frames, where variable width character
sets are in use. This was primarily an issue on Windows, given the limitations
of Unicode/UTF-8 support on that OS.

I want to thank Hamid Moshen for first raising this issue in late March,
providing test datasets in multiple Unicode/UTF-8 character sets that I could
use to reproduce and correct the issues, and his testing of the changes
required.

Warm regards,

Marc Schwartz
