(PR#12016) Full_Name: Paul Eckermann Version: 2.7.1 OS: Windows XP Service Pack 2 Submission from: (NULL) (129.127.183.12) This is the first time I have submitted a bug report, so apologies if I have not followed the correct protocol. If I enter length(rnorm(100*.29)) it returns 28 rather than 29. y<-(1:100)/100 z<-sapply(y,function(x) length(rnorm(x*100))) z!=100*y indicates that it has something to do with multiples of 7 (rounding error?), even though 29, 57 and 58 are the 3 values for which it returns incorrect values of z. I hope that this is not something obvious that I have missed. This can be overcome by doing the x*100 calculation outside the rnorm function, but I don't see why this needs to be done when the answer is (supposed to be) an integer.
