Warning / Error when Importing a .sav
I have two versions of SPSS at work. SPSS 11 running on Windows XP and SPSS 20 running on Linux. Both copies of SPSS work fine. Files created with either version of SPSS open without incident on the other version of SPSS. I.E. - I can create a .sav file with SPSS 20 on Linux and open it on SPSS 11 on Windows without incident. But, if I create a .sav file with SPSS 20 and import the data into either R or PSPP (on Linux), I get a bunch of warnings. The data appears to import correctly, but I am concerned by the warnings. I do not see any warning when importing a .sav from SPSS 11 or other .sav
