Hi,

I am a little new in R but I'm finding it extremely useful :)

Here's my tiny question:

I've got a table with a lot of columns. What I am interested now is to
evaluate how many of 4 columns have a value greater than 1.
I think it can be done with subset() but it will take a very long condition
and become unfeasible if I want to compare more than 4 columns.

I put here a small example

Col1  Col2  Col3  Col 4
1        1       1       1             <-0 columns greater than 1
2        1       1       1             <-1 column greater than 1
4        1       4      1              <-2 columns greater than 1
3        3       3       3             <-3 columns greater than 1

Then I want to filter by that number, my idea is to create a new column
storing the number calculated and subset() by it.

Any hints?
Thanks in advance

JL
