A quick follow up. I installed Frank's Hmisc under R 1.8.0 beta. If
Hmisc is not attached (ie. library(Hmisc)), you get:

> citypro <- sas.get('c:/ndri/cvar/data', member = 'citypro2')
Error: couldn't find function "sas.get"

which you would reasonably expect.

Thus, it seems more likely that Dr. Flom either does not have SAS on his
system or perhaps the SAS executable file (sas.exe? IIRC) is not in Dr.
Flom's 'PATH' on his system if SAS is installed.

HTH,
