Dear Uwe,

The thing that I find funny is that the check of the package on
Windows for R 2.10.x works on r-forge as you can see here:

http://r-forge.r-project.org/R/?group_id=426&log=check_x86_32_windows&pkg=colbycol&flavor=devel

May I be facing some kind of Windows configuration specific issue
here? I am sorry that I am very Windows-illiterate...

This is not something that worries me much "per se", as I am
implementing some changes in the package and the new version does not
resemble the current one too much, but intrigues me quite a lot.

Best regards,

Carlos J. Gil Bellosta
