This topic already came up about a week ago on R-devel
Subject: write.csv suggestion
[ too bad that "R-devel" is not available via RSiteSearch() ...
{I could send you the back archives, Jon, if you are interested} ]
There, Brian Ripley, explained why this is not a bug, since
it works as documented, "CSV" files are well defined entities
and you can always use write.table() if you want to be flexible.
Brian also changed things for R-devel {to be R 2.2.x} such that
its help page, see
http://stat.ethz.ch/R-manual/R-devel/library/base/html/write.table.html ,
now has

which should make the intention of the write.csv*() wrapper
functions a bit more clear.
