Subject: [R] Large matrix into a vector

Hi,

I have a matrix HR(9x27). I would like to make a
single vector with elements: t(HR[,1]) followed by
t(HR[,2]) and then t(HR[,3] ... etc. Is there any neat
way of converting this matrix into a vector rather
doing something like c(t(HR[,1]), t(HR[,2]), t(HR[,3])
..)?

Thanks in Advance.
Kind regards,
Ezhil
