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.
In my experience porting S+ code to R is not very difficult,
as long as your code doesn't rely on manipulating the S+ Windows
GUI, using the S+ importData and exportData functions, using
Connect/C++ or Connect/Java, using the bigdata package, or
using graphlets (applets for interactive graphics in web pages).
Most of the items Bill V. noted are problems when porting from
R to S+ but not the other way around.
I recommend first making your code into a package (the
structure of which is very similar in S+ and R). You
can convert an S+ *.sgml help file to an R *.Rd help file
with 'Splus CMD Sd2Rd file.sgml file.Rd'. Install
the package using both S+ and R and run your tests in both.

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.

Re: [R] Conversion of S+ libraries
Bill D. is quite right, I did have in mind conversion the other way round. I
am happy to concede.
The interesting thing for me is the (relatively) automatic conversion from
.sgml to .Rd format. This is likely to speed things up considerably.
Bill.
