Re: [R] Reading SPSS: underlying numerical codes
Hello,
thank you all very much for your help. With your input and a bit more of
research in addition to that I found the answer:
I import the SPSS file without having R converted the catigorial variables
into factors.
By using the command
attr(mz1$sex,"value.labels")
I get the labels, which are still there!!
Thanks again,
Marion

You didn't say that your workflow involved going backwards and
forwards between SPSS and R.
Importing from legacy formats like SPSS .sav is well developed, with
additional resources from packages Hmisc (spss.get) and memisc
(spss.system.file) with, in the latter case, support for reading
subsets of files.
If you need read/write access with amended SPSS datasets which
coworkers can continue to use existing syntax files for, you may need
to try going via ODBC routes.
This is a rare need, so not too well documented.

Re: [R] Reading SPSS: underlying numerical codes
Dear Michael and Ista,
thank you very much for your answers!
Sorry, I think I wasn't clear about what I need. I will use an example to
explain it again:
I have imported the following data.frame with the following command using
the foreign package:
mz1<-read.spss("myfile.sav",to.data.frame=T)
mz1 asbhh apkz sex
1 1010100131 Female
2 1010100132 Male
3 1010100133 Female
4 1010100301 Male
5 1010100302 Female
6 1010100431 Female
7 1010100561 Male
8 1010100601 Female
R automatically converts the variable sex into a factor which is what I need.
It also imports the levels, which is also what I need.
In my example "Female" has got the number -2 as underlying code in
SPSS and "Male" -3. Now I need this information preserved! If I just
use the command as.numeric I get different numbers than in my spss
file. Is there a way to preserve this information and maybe switch
between seeing the numerical codes and the verbal codes, e.g.:
mz1 asbhh apkz sex
1 1010100131 -2
2 1010100132 -3
3 1010100133 -2
4 1010100301 -3
5 1010100302 -2
6 1010100431 -2
7 1010100561 -3
8 1010100601 -2
Thank you very much for your help in advance,
Marion

Re: [R] Reading SPSS: underlying numerical codes
Hi Marion, I don't have access to SPSS, so it would be hard for me to figure this out for you. I would think that string variables would be imported as strings or factors even when use.value.labels is true, but can't verify that.

Re: [R] Reading SPSS: underlying numerical codes
Hi Ista, thank you for your reply! Yes, I looked at the help sheet but didn't use this command because I would still like the categorial variables to be converted into factors and have the value labels from SPSS imported into R as levels. With the use.value.labels = FALSE? command I do get the same underlying codes as in SPSS but I loose the information about the levels, I think. Does anyone know a way to preserve both?
