Hi
I have read a csv file using the read.table function into R. It contains a list of variables which are numeric in class.
I would like to create a new column based on two columns. Se example below, where C is my desired output.
A B C
1 4 4
2 3 3
3 4 3
2 5 4
- - 4
- - 4
- - 5
- - 5
Is there a clever way of doing this? I don't need to create any output for columns A and B, just a new columns C.
I can't seem to find a function that does this, but I did stumble across the reshape package.
Thanks in advance
