Matrix Transpose

Description:

     Given a matrix or `data.frame' `x', `t' returns the transpose
     (matrix or data.frame) of `x'.

Usage:

     t(x)

Arguments:

       x: a matrix or data frame.

See Also:

     `aperm' for permuting the dimensions of arrays.

Examples:

     a <- matrix(1:30, 5,6)
     ta <- t(a) ##-- i.e.,  a[i, j] == ta[j, i] for all i,j :
     for(j in seq(ncol(a)))
       if(! a[, j] == ta[j, ]) stop("wrong transpose")
