Hello Charles, thank you for the hint.

I mixed the two parameters... Now I get the same problem also at the shell directly typed in: ===================== > as.matrix( replicate(10, sample(x, 3) ) ) [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] 12 15 3 12 7 4 4 14 6 20 [2,] 6 11 1 4 6 19 17 11 19 11 [3,] 20 17 6 8 3 14 19 10 2 14 > > as.matrix( replicate(10, sample(x, 2) ) ) [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] 4 17 18 14 6 11 5 17 13 13 [2,] 14 3 16 12 17 7 20 16 2 17 > > as.matrix( replicate(10, sample(x, 1) ) ) [,1] [1,] 19 [2,] 17 [3,] 12 [4,] 14 [5,] 12 [6,] 13 [7,] 18 [8,] 12 [9,] 5 [10,] 20 > dim( as.matrix( replicate(10, sample(x, 3) ) ) ) [1] 3 10 > dim( as.matrix( replicate(10, sample(x, 2) ) ) ) [1] 2 10 > dim( as.matrix( replicate(10, sample(x, 1) ) ) ) [1] 10 1 > ===================== So, the behaviour is the same... ...but is not really that fine. :( ...how could I avoid the necessity of the transposition of the matrix in the case of only one sample? I mean, it's not extremely a problem, because there are not many loops aroud it, but it looks somehow ugly. :( Ciao, Oliver ______________________________________________ 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.
