[R] general question on Spotfire

[Frank Harrell]

As a slight aside, Tibco/Spotfire originally planned to provide a capability
to load R packages into S-Plus.  This always seemed to me to be a hard thing
to do, and if my understanding is correct, this proved to be too difficult
to do in S-Plus, at  least for large packages such as mine.
