datatype | R Documentation |
Tries to figure out the correct datatype for image. Useful for image masks - makes them binary if
datatyper( img, type_string = NULL, datatype = NULL, bitpix = NULL, trybyte = TRUE, warn = TRUE )
img |
nifti object (or character of filename) |
type_string |
(NULL) character of datatype and bitpix. Supercedes
both datatype and bitpix. If specified
|
datatype |
(NULL) character of datatype see
|
bitpix |
(NULL) character of bitpix see
|
trybyte |
(logical) Should you try to make a byte (UINT8) if image in c(0, 1)? |
warn |
Should a warning be issued if defaulting to FLOAT32? |
object of type nifti
img = nifti(array(rnorm(10^3, sd = 1000), dim = rep(10, 3))) rimg = round(img) newnii(datatyper(rimg)) rimg = datatyper(rimg, type_string= "FLOAT32")
