Not sure whether this is the problem but calling your data frame
data.frame is not a good idea.

Thank you very much.
After that I have the following error:
cols<- c("GrMM", "RELG", "CASTE1", "SECTOR", "SECTOR4","AGE", "MARITAL", "JOBSTATUS", "ENG", "EDU", "PARENT_EDU",
"MASSMEDIA_F", "MASSMEDIA_M", "HomeComputer", "HomeInternet")
for (I in cols) {data.frame[,i]= as.factor(data.frame[,i])}
Error in sort.list(y) : 'x' must be atomic for 'sort.list'
Have you called ‘sort’ on a list?

You are missing a comma between "MARITAL" and "JOBSTATUS".

I run this command for converting the numerical variable into factor. However,
I get the following error message.

Please help.

Hello,
Though Bert's and David's answers are what you should do, note that some R
functions that need factors will coerce their input variables when necessary.
Have you tried to run the code you haven't posted without coercing to factor?
It might run...
Hope this helps,
