[R] What is the fastest way to combine all columns of a matrix to one column?

[Bert Gunter]

Mod Rolf's question, the answer probably is: do nothing  -- it already
**is** a single column.

If you read the section on arrays and matrices in "An Intro to R"
*carefully* (this is part of every standard R distro) you will be
enlightened. Have you read it? If not, why not?

If mat is your matrix,

c(mat)

may also be enlightening.
