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?
