There was a wrong DLL for a short while in the old 1.5.2 version (I
fixed a R2.12.0 related issue and unfortunately introduced this
error). If you delete the old xlsReadWrite package and re-install the
package (either from CRAN or see www.swissr.org/download) it really
should work.

What's the 'library(xlsReadWrite)' startup message? For the current
version it should be: 'xlsReadWrite version 1.5.3 (0b78c1)'. Could you
please give more details about 'I installed xlsReadWriter today'
(which CRAN mirror, 'R.version' and '.Platform' output, is there only
one 'xlsReadWrite.dll' file on your system). It is supposed to work
and I am unable to find any problem. Thanks a lot!

There are many ways to read/write data in R:
* Other than load/save you could use read.table/write.table (see R
Data Import/Export).
* Using Excel files is not the recommended way. However when you
want/need it, there are several options (see


PS. not that I mind to discuss things here, but as these are package
specific problems I'd suggest to switch to the xlsReadWrite forum
(http://dev.swissr.org/projects/xlsreadwrite/boards). You also can
create an issue
(http://dev.swissr.org/projects/xlsreadwrite/issues/new) or just send
an email to 'support' at 'swissr.org').
