Have you tried reading the file with the read.xport() function in the foreign
package, which is part of the default R installation?
require(foreign)
?read.xport
I would start a fresh R session, just to be sure that the SASxport version is
not used unintentionally.
There might be a bug in the SASxport version of the function, which apparently
uses some of the foreign package version's code, or there might be something
about your xpt file that is causing a problem. You may need to contact Greg,
who is the package maintainer for SASxport, to get a sense from him as to what
would trigger the error you are experiencing. Otherwise, you may have to trace
through the code (see ?debug, for example) with your file and see if you can
identify a trigger.
