In neuroconductor-releases/NiftiArray: HDF5 Delayed Array for Nifti Objects

Description

Reads multiple NiftiArray objects into elements of a list. TODO: Add more detail based on BUG fix.

Usage

NiftiArrayList(x, ..., verbose = FALSE)

Arguments

x	a character or list of objects to be called with writeNiftiArray
...	additional arguments to pass to NiftiArray
verbose	show progress bars if pbapply package installed.

Value

A list of class NiftiArrayList, which is a list if NiftiArray objects

Examples

nii_fname = system.file("extdata",
"example.nii.gz", package = "RNifti")
nii_fname = rep(nii_fname, 3)
res = NiftiArrayList(nii_fname)
if (requireNamespace("pbapply", quietly = TRUE)) {
   res = NiftiArrayList(nii_fname, verbose = TRUE)
} else {
   testthat::expect_warning({
   res = NiftiArrayList(nii_fname, verbose = TRUE)
   })
}
testthat::expect_is(res, "NiftiArrayList")
mat = as(res, "NiftiMatrix")
arr = as(res, "NiftiArray")
h5 = unlist(DelayedArray::seedApply(res, slot, "filepath"))
res2 = NiftiArrayList(h5)
testthat::expect_is(res2, "NiftiArrayList")
mat = as(res2, "NiftiMatrix")
arr = as(res2, "NiftiArray")
