Dear all,
I found that the new feature of the comment.char="#" argument in the
read.table function truncated my data while the data set actually contains
'#'. We analyze lot of data that contain '#'. This is really annoying and
it is also not compatible earlier version of R. I searched the R archive
and found the following message for the scan function. Is it possible to
change the default to " " in read.table ?
Thanks,
Ren

It already has been. The NEWS for R-patched / R-devel says:
o The default has been changed to scan(comment.char="") for
consistency with earlier code (as in the previous item).
