## Loop Repetition

 Hey guys, I'm trying to write a loop that will repeat an action for a stipulated number of times. I have written some code but i think i'm missing something. for (x in 5) {   repeat{     x = runif(1:4, min = 0, max = 1)     print(x)     if (x== var_1[5]){       print("done")     }     print(x)} } The goal is to generate the random number 5 times. Please help....         [[alternative HTML version deleted]] ______________________________________________ [hidden email] mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.

## Re: Loop Repetition

 Is there anything wrong with just doing this? x <- runif(5, min = 0, max = 1) Also note that you use x to be at last 2 things: in for (x in 5) { you set it to 5, and then in the loop you x = runif(1:4, min = 0, max = 1) you make it a vector of length 4. You also fail to use break to stop the repeat (something I never knew existed in R!).

## Re: Loop Repetition

 In reply to this post by Tolulope Adeagbo Hi Tolulope, The "in" operator steps through each element of the vector on the right. You only have one element. Therefore you probably want: for(x in 1:5) ...

## Re: Loop Repetition

 Thanks guys, I've tried all you're suggesting,  both for (x in 1:5) and break, but I cant seem to ascertain when the loop has generated a vector of 4 random numbers  5 times.
