[R] reshaping a data frame

[John Kane]

Why not just unlist the data.frame and specify the number of rows in a matrix each time you need look at a different layout, assuming I understand the question.

Example
===================================================================

aa <- data.frame(1:100)
bb <- unlist(aa)
(cc <- matrix(bb, nrow=20))

====================================================================
