A new package called WriteXLS (Version 1.5.0), containing a single
function of the same name, is now available via CRAN. The package is
made available under the GPL, version >=2.
The function is based upon a Perl script that I have previously posted
on r-help, now wrapped in R for convenience. It provides a cross-
platform function to create Excel 2003 (XLS) files from one or more
data frames. Each data frame will be written to a separate named
worksheet in the Excel spreadsheet. The worksheet name will be the
name of the data frame it contains.
The package requires that Perl and several specific Perl modules are
installed in order to function. These modules, which may already be
installed on systems with Perl installed, include:
With the exception of the last three modules listed, for convenience
all are included in the CRAN package and will be made available by
adding the installed package path for these modules to the Perl @INC
The last three modules (Encode, File::Glob and Text::CSV_XS) are 'XS'
based Perl modules, meaning that they call external C routines. Thus,
they are not included as they require local compilation using the
particular version of Perl installed on the user's system.
As a result, only source versions of the WriteXLS package will be made
available. This is because the examples on the function help page will
not run without Perl and all of these modules being available on the
user's system. Hence the package will presently fail 'R CMD check' on

Many thanks to Prof. Brian Ripley for his assistance with the testing
of this package prior to release.
