R devel - Jul 2006 - % symbol in .Rd files?

Hello,

I am encountering problems when there is a '%' character in
package .Rd files. More precisely, CRAN is having problems
with these characters when running check, whereas I am not
seeing any problems under Linux and Windows.  I did see
these problems, and found that escaping the %'s fixes the
problem in my testing, but apparently this does not fix the
problem when check is run at CRAN.

I suspect that there are some compatibility problems between shells,
TeX, or perl versions, or perhaps the check on CRAN goes
through more levels of preprocessing?

I can probably fix this problem by removing all '%' chars
from my .Rd files, but this doesn't seem like a very
natural solution.

Any ideas?

Thanks,
ds

definitely not.  Other packages have them as well,
without giving any CRAN hickups

No, you should find and fix the problem.

We need examples which -- at least for you -- produce the
problem.  You could post a small tar file (mime-types
'application/x-tar'
or 'application/x-compressed-tar' are accepted for R-devel) if
you want.
