Thanks for all the insightful responses that help me solve my problem.
The original question is: how to call SAS from R
The solution is as below:
If my sas code, test.sas, is in directory c:\ncme06\sas codes, then the
following codes works
> system('"c:\\program files\\sas institute\\sas\\v8\\sas.exe"
"c:\\ncme06\\sas codes\\test"')
Things to notice:
1. need a single quote for the system function
2. need a double quote for BOTH the sas.exe and test files.
Thanks again.
David

Sorry that does not work. The Windows way is to quote it: e.g.
system('"c:/Program Files/Mozilla Firefox/firefox.exe"')
works (note the two sets of quotes), and this is explained with an example
on the help page ?system, so please do as the posting guide asks and read
the documentation ....
