Hi Petr,
I am looking for a general procedure that I can use with any package of R.
As to my current experience it probably will happen that I need a
procedure from another package than hmisc or memisc and the my solution
shall work even than so that I do need to find another way to do it.
Kind regards
Georg

Seems to me that it is work for factors
nnn <- sample(1:4, 20, replace=TRUE)
q1 <-factor(nnn, labels=c("Less than 18 years", "18 to 30 years", "31 to
60 years","61 years and more"))
You can store such variables in data.frame with names "q1" to "qwhatever"
and possibly "Subject"
And you can store annotation of questions in another data frame with 2
columns e.g. "Question" and "Description"
Basically it is an approach similar to database and in R you can merge
those two data.frames by ?merge.

It seems to me strange. What prevents you to use functions from Hmisc?
