You can add an attribute to a variable. In the sas.get function in the Hmisc package for example, when importing SAS variables that have PROC FORMAT value labels, an attribute 'sas.codes' keeps the original codes; these can be retrieved using sas.codes(variable name). This could be done outside the SAS import context also.
