Hi All, In 2005, I noted that when I used read.xport function in the foreign package to import a SAS transport file (.xpt) with multiple files imbedded in it, data frames from some of the files were not created. Since then, I discovered that the information from the missing files is being read into one dataframe, but the data appear corrupted. This has been noted before by Dr. Harrell (in 2003). I am wondering if anyone might have a fix that isn't available yet? Gary A. Nelson.
