Create Quantile Image

Creates output image of the quantiles that each voxel is in, after applying the mask

quantile_img(img, mask = NULL, ...)

Arguments

img	Character vector, or object of class nifti
mask	Mask to determine cumulative distribution function (cdf) from
...	Additional arguments to pass to ecdf

Value

Object of class nifti

Examples

set.seed(5)
dims = rep(10, 3)
arr = array(rnorm(prod(dims)), dim = dims)
nim = oro.nifti::nifti(arr)
qimg = quantile_img(nim)
qarr = quantile_img(arr)
testthat::expect_equal(qarr, array(qimg, dim = dim(qarr)))
qimg = quantile_img(nim, mask = nim > 0)
