Yes, quite a bit of R is converted ratfor.

There is `ratfor' (from AT&T) and then there is at least one `public
domain' clone. My RH7.2 came with neither.  I tend to use the AT&T version
on Solaris, as it seems better-behaved than the clone that is available
for e.g. Debian.

It really depends on the version details of both tools.  Your report is
about as non-specific as it is possible to get!  The only problems I have
had have been bugs in the ratfor -> f77 translation by the PD ratfor.
