ifelse question
Dear R-helpers,
How come that in the following code the rnorm() function is evaluated only once for each branch of the 'ifelse' ?
x <- rnorm(10)
y1 <- ifelse(x > 0, rnorm(1) , rnorm(1))
What is the right way to make it called/evaluated for each row, apart from a 'for' loop ?
Thanks,
Jacques.
