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

Subject: [R] Variable labels and value labels
Hi All,
I am using R for social sciences. In this field I am used to use short
variable
names like "q1" for question 1, "q2" for question 2 and so on and label
the
variables like q1 : "Please tell us your age" or q2 : "Could you state
us your
household income?" or something similar indicating which question is
stored
in the variable.
Similar I am used to label values like 1: "Less than 18 years", 2 : "18
to
30 years", 3 : "31 to 60 years" and 4 : "61 years and more".
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.
I know that the packages Hmisc and memisc have a functionality for this
but
these labeling functions are limited to the packages they were defined
for.
It seems to me strange. What prevents you to use functions from Hmisc?
Regards
Petr
Using the question tests as variable names is possible but very
inconvenient.
I there another way for labeling variables and values in R?
Kind regards
