Hi Jim, Thank you so much for your suggestion. I have tried ".csv" and ".sav". ".sav" works better. I learned "DAT file" from the internet. There were some similar discussion about wirte.foreign() before. I don't really know how the transfermation of the files between R and SPSS works. When i got several files, I was a little lost. But I should emphasize my main problem which is the character variable is not read shown up in the file. I mean i want to see e.g., 000CF7CC in the data instead of its corresponding value 1 defined by SPSS automatically. Another problem is how to keep the variable names in the "data file".
Normally, when you write out a data file in SPSS format from R, it should correspond to an SPSS "system" or .SAV file. I would expect to see something like this: library(foreign) write.spss(df,file="k:/res.sav") Then in your SPSS file: GET /FILE="k:\res.sav". I don't think the .SAV extension is necessary, but I'm not sure. Jim
