aperm(a, perm, resize=TRUE)
a |
the array to be transposed. |
perm |
the subscript permutation vector. |
resize |
a flag indicating whether the vector
should be resized as well as having its elements reordered
(default TRUE.) |
A transposed version of array a, with subscripts permuted as
indicated by the array perm. If resize is TRUE, the
matrix is reshaped as well as having its elements permuted.
The function t provides a faster and more convenient
way of transposing matrices.

# interchange the first two subscripts on a 3-way array x x <- array(1:24, 2:4) xt <- aperm(x, c(2,1,3)) all( t(xt[,,2]) == x[,,2] )
