[R] creating a matrix subset based on a threshold cutoff

[rich at thevillas.eclipse.co.uk]

   sorry, it would probably better be described as a table

   thanks

     You have a table or matrix?
     if is matrix:
     set.seed(123)
     x <- matrix(rnorm(100), 10, 10)
     cutoff <- -1.5
     do.call(rbind, apply(x, 1, function(.x).x[any(.x < cutoff)]))
