Hello!

I need to calculate the maximum of each row of a data frame.
This works:

  x <- data.frame(a = 1:5, b=11:15, c=111:115)
  x
  do.call(pmax, x)
[1] 111 112 113 114 115

However, how should I modify it if my data frame has NAs?
I'd like it to ignore NAs and return the maximum of all non-NAs in each row:

  x <- data.frame(a = c(1:5), b=11:15, c=c(111:114,NA))
  x
I'd like it to return:
[1] 111 112 113 114 15

Thanks a lot!
