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?

You could try the following:

matrix(V1, nrow=5)

  but note what happens when the length of V1 is not a multiple of 5.

Thanks in advance...
