Hi all! I have a list of matrices and I want to multiply the ith element of the list with the ith element of a another vector. That is, > LL <- list(A=diag(3),B=diag(3),C=diag(3)) > vec <- 1:3 > for(i in 1:3) + { + LL[[i]] <- LL[[i]]*vec[i] + } > LL $A [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 1 0 [3,] 0 0 1 $B [,1] [,2] [,3] [1,] 2 0

I'm probabily wrong, but is there a bug in the binary distribution of Samba on Ubuntu 14.04.01 Little Endian, maybe
