Matrix Rotation
Description
Rotate matrices for 90, 180, or 270 degrees..
Usage
rot90(a, k = 1)
Arguments
a
numeric or complex matrix
k
scalar integer number of times the matrix will be rotated for
90 degrees; may be negative.
Details
Rotates a numeric or complex matrix for 90 (k = 1), 180 (k = 2) or
270 (k = 3 or k = -1) degrees.
Value of k is taken mod 4.
Value
the original matrix rotated
Examples
a <- matrix(1:12, nrow=3, ncol=4, byrow=TRUE)
rot90(a)
rot90(a, 2)
rot90(a, -1)
