However, the sas.get function still appears to be broken on Windows platforms (or Windows is broken :-).  I know how to fix the problem, but I am always looking for approaches where I don't have to fix things.   It may well be that the better documentation provided by sas.get will prove to out weigh the inconvenience of having to source an edited version of sas.get for my regular use.

Daniel,

if the function is broken and needs to be fixed, why don't you report 
your findings (both the error with reproducible code) as well as your 
bugfixes to the package maintainer?

Best wishes,
Uwe



> As for moving data from R to SAS, I don't know of any methods other than the RODBC package with the SAS ODBC driver for writing SAS datasets.  Yes, I can write to csv or other file types that SAS can import, but if I can eliminate extra steps when going from R to SAS then that is a plus for me.
