Ok thank you. That does work. What does
apply(ttt, 1, function(x) x[is.infinite(x)] <- 0 )
this return. I get all 0's,but can you explai why ?
Thank you.

Hi,
A slight modification corrects this:
ttt <- data.frame(A = c(Inf, 0, 0), B = c(1, 2, 3))
apply(ttt, 2, function(x) {x[is.infinite(x)] <- 0; x})
and please do use spaces in your code. It is much more legible. Most
notably spaces are after commas.
Cheers,
Josh
