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. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
