Compatibility issues with R and S+

[Paul.Reynolds@ILIM.COM]

Hi,

[Apologies to readers of R-help mailing list who have already been mailed my issues below, which are now being put to the S community via the S-news list...]

Can anyone please advise if there is a neat way to 'share' libraries of (previously developed) S+ code with R? 

Specifically, within S+ I can use the attach(what = "<Chapter Directory>", pos = 2) command, to retrieve previously developed functions and variables to position 2 in the search list.  [Some may be intentionally masked by what's in the current working chapter].  Can I similarly directly retrieve these functions and variables within R at position 2 in the search list? 

I have been able to achieve limited success via a 2-stage approach of data.dump (or dump) within S+ and subsequent data.restore (or source) functionality within R.  However, how do I restore objects to (a new R object at) position 2 as opposed to my workspace (e.g. env argument defaulting to .GlobalEnv via data.restore)?

With regard to the 'attach' functionality within R I have been able to retrieve previous functions developed within R and saved as an R data file.  So maybe my issue boils down to 'converting' the S+ <Chapter Directory> into an R data file?  I hope there is indeed such a simple solution.

Any help or advice would be greatly appreciated.
Thanks and kind regards
Paul
