[R] transpose rows and columns for large data

[Bert Gunter]

It is probably worth mentioning that this (i.e. transposing a data
frame) can be a potentially disastrous thing to do in R, though the
explanation is probably more than you want to know at this point (see
?t  and follow the 'as.matrix' link for details).  But if you start
getting weird results and error/warning messages when working with
your transposed data, at least you'll know why.

Cheers,
Bert

Is there a way totranspose all the data at one time instead of piece by piece? One dataset has agreat amount of rows and columns.
