[R] Vector to Matrix transformation

Hi R, I have a vector V1 of unknown length, say n. I need to convert this into a matrix C of row size=5, and accordingly the column should be updated. I tried with: C=as.matrix(V1,5,n/5) But it is not working...Could somebody help me on this? Thanks in advance... [[alte

[R] vector to matrix transformation

Dear, Some analysis (linear regression) can only be done from a vectorized dataset whereas others require a matrix (Mantel tests). I use the two analyses and thus need to format my data in matrix and vector. I spent some time trying to solve the problem and I just gave up. Did anyone knows ho
