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?

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

An internet search for this error would have told you what causes it. Finally: - Your loop will not work because your loop variable is I and the index is i; they are different in R. You'll just update the same column (i) lots of times, assuming i is defined. - The error message arises from a call to factor() in as.factor(). It tells you that the column being converted is not a simple vector. That in turn tells me that you have not constructed your data frame correctly. I can't tell you what you did wrong there. - As another poster has said, data.frame is the name of a function - one that construicts a data frame. R can often tell which you want, but it is never safe to use the name of a function as the name of a data object. Use a different name for your data frame.

Hi
You could instead of selecting columns by name select them by number
Something like
your.data[,2:3] <- do.call(data.frame, lapply(your.data[,2:3], factor))
or you could construct a vector of column numbers
x <- c(2,3)
Cheers
Petr
