test seems to be a data frame or list with one variable. So you have

Hello,
I figure this is quite a simple problem really, but since I'm quite
new to R I need to ask:
If I have a data frame:
str(test) :
$ classcol: Factor w/ 3 levels "1","2","3"
How do I convert the entries in this column to numbers. I.e., I want
to be abl to do simple calculations like test[1,
3 matches
