i am the author of read.ssd, and did not accommodate sas for
windows in the creation of that function.  i do not know how
sas is called under windows, but it is possible that if you
learn how to invoke sas through the R "system" command, you
can supply the invocation command as the "sascmd" parameter
to read.ssd

other ways of transferring the information from SAS to R
include 1) using a put statement to write the data out record
by record into a whitespace delimited file, and then using
read.table in R to collect the data for use in R, 2) using
read.ssd on a unix system, saving the resulting R object,
and then transferring the R object back to windows.
