I am not sure if you have had this answered already. You definitely cannot just copy the binary objects into a .RData workspace. On the S-PLUS side, I would try ?data.dump (and particularly, its argument oldStyle if you have S3/S-PLUS 2000 or earlier objects), and/or ?dput to get your S-PLUS objects exported to ASCII format. Then from the R side, see ?source and ?dget to import things into R objects. I do not recall off-hand what the best combinations and argument settings are for the most common situations. But I recall the reliability being pretty high in my practice if not perfect, which is more than I could ask for. I'd also like to suggest that if you do not already, you might want to make a habit to use and keep files of source code with objects that you create, especially functions and calls to create data.frames, etc.... As wonderful as R is, I find S-PLUS is still needed a lot in my work, so when you need to work with both, having a file of the source commands is most convenient (actually, I personally find it absolutely essential).
