Thanks for the reply. I do however need to create an .xls binary from R. The
system I'd like R to talk to only accepts .xls format files and this needs
to be automatic. I already have this working in S-PLUS and I was thinking of
porting to R. I saw the Excel-R-Interface mentioned in the archives so maybe
I could call Excel to load up the .csv and save as an .xls, but I'd prefer
to keep things simple if possible and write the .xls format directly from R.
Its got to be possible since Insightful managed to do it, now whether its
difficult??

Insightful can licence and incorporate closed-source libraries and
obtain information under nondisclosure agreements... (not that I know
how Insightful operates, but the publicly available information is
certainly scarce).

R can speak ODBC via the RODBC package. An .xls file can be used as an
ODBC source. This can be used to read spreadsheets (after some
headbanging in setting up the DSN, I recall), so you might also write
into them with sqlSave()? Read Ch4 in the R Data Import/Export  manual
and you'll know roughly what I know.
