[R] read.spss question warning compression bias

[Peter Flom]

Hello again

I have a file from SPSS in .sav format.

when I run

library(foreign)
cvar<-as.data.frame(read.spss("c:\\NDRI\\cvar\\data\\cvar2rev3.sav"))

I get a warning

Warning message: 
c:\NDRI\cvar\data\cvar2rev3.sav: Compression bias (0) is not the usual
value of 100. 

The data appear to be OK, but I am concerned.  

 (I tried searching the archives and the documenation for data import
export, but saw nothing).


Thanks as always

Peter
