In USGS-R/mda.streams: Data Preparation, Access, and Analysis Functions for the Powell Center Continental Stream Metabolism Project

Download file[s] to local destination

Description

Download one or more files to a user-specified (or temp file) location

Usage

download_item_files(item_ids, item_names, files = NA, folder = tempdir(),
  on_remote_missing = c("stop", "return_NA"), on_local_exists = c("stop",
  "skip", "replace"))

Arguments

item_ids	the item id[s], or NA if an id could not be found. an item_id will be ignored in the very special (but potentially common and speedy) case that files is specified (not NA), all specified files for an item are already available locally, and on_local_exists=='skip'.
item_names	character names by which to refer to the respective items in messages
files	list of character vector[s] of file names to download, one list element per item_ids. if the default is used, all files from each site will be downloaded. may also be passed as a single character vector to be replicated once for each item_id
folder	string for a folder location where files should be saved, or a vector of as many folders as there are item_ids
on_remote_missing	character indicating what to do if the
on_local_exists	character indicating what to do if the folder already contains a file with the intended download name

Value

file handle (character path) for the downloaded file, or NA if the timeseries is unavailable on ScienceBase
