As Peter noted, the phrase 'side effect'
Hi All,
Thank you very much for all your suggestions. It's a
great learning for me. All the three suggested
solutions seem working. I don't know what 'side
effects' that you were talking about. To summarize the
responses:

Is this something like what you want?
ab <- rep(1,4)
bb <- rep(2,4)
cc <- rep(3,4)
mydata <- data.frame(ab,bb,cc)
unlist(mydata)
unlist(data.frame(t(mydata)))

We have already seen three solutions.
I don't like to see the use of c() for its side effects. In this case
Marc's as.vector seems to me to be self-explanatory, and that is a virtue
in programming that is too often undervalued.

A matrix is just a vector with a dim attribute, so if you remove
the dim attribute it'll be a vector. The elements of a matrix
are stored columnwise so you'll get just what you want, if i get
your question right.
