Hallo, I'll need a matrix with n rows of the an identical vector.> h[1] 3 3 3 3 2 2 2 The nmatrix should look like this:> x<-rbind(h,h,h) > x[,1] [,2] [,3] [,4] [,5] [,6] [,7] h 3 3 3 3 2 2 2 h 3 3 3 3 2 2 2 h 3 3 3 3 2 2 2 but I need n rows which must be variable. Can anyone help me? thanks Andreas [[alternative HTML version deleted]]

try this:
h <- rep(3:2, c(4, 3))
############
n <- 10
matrix(rep(h, n), nrow = n, byrow = TRUE)
Best,
