[R] Create Matrix with Float32 values

Dear R_Help: The following gives me a matrix with integer values. z= matrix(rep(10:1, each= 10), ncol= 10, byrow=TRUE)> str(z) int [1:10, 1:10] 10 9 8 7 6 5 4 3 2 1 ... How do I specify that I want Float32 values instead. Thanks,Chris

[R] for loop populate matrix

Dear List, I am trying to populate a matrix using a for loop.This works. > four<- matrix(nrow=4,ncol=5)> for (j in 1:ncol(four)){+ for (i in > 1:nrow(four)){+ four[i,j]<-i-1}+ }> print(four)     [,1] [,2] [,3] [,4] > [,5][1,]    0    0    0    0    0[2,]    1    1    1    1    1[3,]    2    2
