Dear List,

I apologize in advance if this is silly. I tried to replicate an analysis I did previously in SPSS using R, and was surprised to find different results.

So my question is: shouldn't the following SPSS syntax


Yeld the same results of the following R command


I assume the is some difference in some default options.Or maybe it was a problem when the data was imported. After using the read.spss in the foreign package, I got the following warning message:

Unrecognized record type 7, subtype 16 encountered in system file

Thanks in advance for the help and apologies for the trouble,
