rep( sum(sample(1:6,100,replace=T)), times=10) Read carefully what you wrote. You asked R to sum a single sample, then make ten copies of the sum.
You need to take ten samples, then sum each. apply() would be helpful. -----Original Message----- I'm trying to get R to simulate the sum of the values on 10 fair dice (yes, it's related to a homework problem, but is not the problem itself). I tried to do this: > rep(sum(sample(1:6,100,replace=T)), times=10) [1] 341 341 341 341 341 341 341 341 341 341 ______________________________________________ R-help@r-project.org 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.
