[R] If then test

[GlenB]

Do you actually need the intermediate result (the vector of 1's and 0's), or
just the result - the total number of columns? 

Is the number you're comparing to different for each column?

Assuming the answers are "just the result" and "comparing to the same
number"

x <- matrix(c(4,5,7,2),nc=2)
num <- 6
sum(apply(x<num,2,all))
