It would certainly not be straightforward, unless Tibco has done a lot of work to make it possible in recent years, (which is not unlikely). They have done a lot of work in the other direction, i.e. enabling R packages to be used within S-PLUS.
S-PLUS has the concept of a "chapter", which roughly corresponds to a working directory in R, but also the package. The chapter is already strongly file structured, and quite different to the way R has of doing things. There is also the notorious scoping rule problem which makes translation of advanced code quite tricky, if not actually impossible. S-PLUS does not (or at least did not) have the equivalent R environments, for example. It has a concept of "frames", which is a very different thing and much less flexible. When moving from S-PLUS libraries to R packages, my approach would be to go back to the code, get it working in R and then build the R package. The middle part, getting it going in R, may take some time. -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Treacy, Glenn Sent: Thursday, 21 October 2010 7:27 PM To: r-help@r-project.org Subject: [R] Conversion of S+ libraries Does anyone have any advice on converting S+ libraries to R packages?
