Download optional test data for neurosurf

Downloads larger test data files that are not included in the CRAN package due to size constraints. These files are hosted on GitHub releases and are useful for running the full test suite or exploring additional file formats.

Usage

neurosurf_download_testdata(
  files = "all",
  destdir = NULL,
  overwrite = FALSE,
  quiet = FALSE
)

Arguments

files

Character vector of files to download. Use "all" to download all available test files. Available files:

• "rscan01_lh.gii" - GIFTI surface file (30 MB)

• "rscan01_lh.niml.dset" - NIML surface dataset (22 MB)

• "rscan01_rh.niml.dset" - NIML surface dataset (22 MB)

destdir

Destination directory. Defaults to extdata within the installed package location. If the package location is not writable, defaults to rappdirs::user_cache_dir("neurosurf").

overwrite

Logical; if TRUE, re-download files even if they already exist. Default is FALSE.

quiet

Logical; if TRUE, suppress progress messages.

Value

Invisibly returns the paths to downloaded files.

Details

The test data files are hosted on GitHub releases for the neurosurf package. This function requires an internet connection to download the files.

If you are running tests locally and want the full test suite, run neurosurf_download_testdata("all") once after installing the package.

Examples

if (FALSE) { # \dontrun{
# Download all test data
neurosurf_download_testdata("all")
