This function allows users to download specific modalities for Kirby21 data sets. This allows this package to be on CRAN

download_kirby21_data(
  modality = kirby21.base::all_modalities(),
  progress = TRUE,
  force = FALSE,
  outdir = NULL
)

`modality`	modality of images that are to be downloaded. You must have the package downloaded for that modality.
`progress`	Should verbose messages be printed when downloading the data
`force`	If the package of that modality is not installed stop. If `force = FALSE`, then this will download the data but not really install the package.

A logical indicating the data is there.
