Download Files from DNAnexus — dx

Download files from the currently selected DNAnexus project and folder. This function provides a convenient wrapper around the `dx download` command.

Usage

dx_download(
  files,
  local_dir = ".",
  overwrite_existing = TRUE,
  unzip_files = FALSE
)

Arguments

files: Character vector of DNAnexus file identifiers or paths to download.
local_dir: Character string specifying the local directory to download files to. If NULL (default), uses the current working directory.
overwrite_existing: Logical. If TRUE (default), overwrites existing local files with the same name. If FALSE, skips files that already exist.
unzip_files: Logical. If FALSE (default) does nothing. If TRUE, files with the '.gz' extension will be decompressed using the `gzip` utility. OFH decided to remove `R.utils` from the JupyterLab app, so decompression is no longer possible from within R (thanks guys!).

Value

Character vector containing the download command output (stdout)

Examples

if (FALSE) { # \dontrun{
# Download a single file
# dx_download("file_id_123")
#
# Download multiple files to a specific directory
# dx_download(c("file_id_1", "file_id_2"), local_dir = "./downloads")
#
# Download with overwrite disabled
# dx_download("file_id_123", overwrite_existing = FALSE)
} # }
