[R] question related to S-Plus

[Rick Picard]

Dear r-help,
      Having used S-Plus for many years, it has
been suggested to me that I could benefit from
learning R.  A question to this end, though.
Would all of my existing S-Plus arrays, functions,
and so on have to be re-created from scratch in R,
or is there a way to copy them into the .Rdata
directory?  The answer to this question has major
implications for the extent to which R is attractive
in the near term, and any enlightenment would be
much appreciated.

Thanks,
Rick Picard
