Of course this is a trivial task:

text.in <- readLines(file.in)
matrix.in <- strsplit(text.in, "[ \t]+")

You probably want

write.table(t(read.table(file.in)), file = file.out, row.names = FALSE, col.names = FALSE)

Uwe Ligges


# 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?
