[R] SPSS and R ? do they like each other?

[Michael Reinecke]

Thanks again for your answer! I tried it out. write.foreign produces SPSS syntax, but unfortunally this syntax tells SPSS to take the names (and not the labels) in order to produce SPSS variable labels. The former labels get lost.

I tried a data frame produced by read.spss and one by spss.get. Here is the read.spss one (the labels meant to be exported are called "Text 1", ...):

jjread<-  read.spss("test2.sav", use.value.labels=TRUE, to.data.frame=TRUE)
> str(jjread)
`data.frame':   30 obs. of  3 variables:
 $ VAR00001: num  101 102 103 104 105 106 107 108 109 110 ...
 $ VAR00002: num  6 6 5 6 6 6 6 6 6 6 ...
 $ VAR00003: num  0 0 6 7 0 7 0 0 0 8 ...
 - attr(*, "variable.labels")= Named chr  "Text 1" "Text2" "text 3"
  ..- attr(*, "names")= chr  "VAR00001" "VAR00002" "VAR00003"
>      datafile<-tempfile()
>      codefile<-tempfile()
>      write.foreign(jjread,datafile,codefile,package="SPSS")
>      file.show(datafile)
>      file.show(codefile)


The syntax file I get is:

DATA LIST FILE= "C:\DOKUME~1\reinecke\LOKALE~1\Temp\Rtmp15028\file27910"  free
/ VAR00001 VAR00002 VAR00003  .

VARIABLE LABELS
VAR00001 "VAR00001" 
 VAR00002 "VAR00002" 
 VAR00003 "VAR00003" 
 .

EXECUTE.


I am working on R 2.2.0. But I think a newer version won ´t fix it either, will it?

Greetings,

Michael

library(foreign)
?write.foreign

write.foreign(df, datafile, codefile, package = "SPSS")

   The codefile generated is SPSS syntax which will read the datafile and create SPSS variable and value labels.
