I like the sas.get function from the Hmisc package. But if for some reason the OP can't or doesn't want to use sas.get, it is fairly easy to add a parameter to the read.ssd function to limit the number of records read from the SAS dataset being exported. If the OP or anyone else is interested, they can contact me off-list and I will provide an example (no need to clutter up the list).
