Dear R users,
I have a very simple question. What is the easiest way to recode data in
of the columns of a data frame and put it into a new column?
For example, here is a simple data frame:
How do I add a new column to data - 'var2' in which I group values in
1 1 4
2 2 4
3 3 5
It's got to be simple, but I can't find it...
