Transform array with orthogonal permutation matrix

Source: R/transform.R

Given an orthogonal permutation matrix \(T\), an array of dimensions and a one-dimensional representation of data. It will return a transformed array with the transformed dimensions.

performPermutation(T, real.dimensions, data, verbose = FALSE)

Arguments

T

is an orthogonal matrix.
real.dimensions

is a one-dimensional array, representing the length of dimensions in data.
data

is a one-dimensional representation of the data to be transformed.
verbose

is a logical variable (default = FALSE) that allows text-based feedback during execution of the function.

Details

This function is mainly used by the reorient function to transform nifti data into neuroradiological convention.
