[R] Hyper-elegant code to get a text file, transpose it, and write it

Of course this is a trivial task:

text.in <- readLines(file.in)
matrix.in <- strsplit(text.in, "[ \t]+")
# matrix.out <- transpose matrix.in
# loop over the lines of matrix.out creating text.out
writeLines(text.out, file.out)

What is the _most elegant_ way to write the transposition of matrix.in (that is _not_ a matrix) and the pasting of the lines of matrix.out?

PS: this is not a homework, this is evangelism to a Visual Basic programmer :-)
