[R] Row count on criteria

2012-06-01 Thread Filoche
Hi everyone. I would like to count number of row higher than 0 for each column in a dataframe. For instance, I was using something like: YY = replicate(5, rnorm(10)) apply(YY,2,">",0) This give me a boolean matrix, but how to have the count of row with numbers > 0 by column? Thank in advance
