download_data: Use curl to download a file.

In FedData: Functions to Automate Downloading Geospatial Data Available from Several Federated Data Sources

Description

This function makes it easy to implement timestamping and no-clobber of files.

Usage

download_data(url, destdir = getwd(), timestamping = T, nc = F,
  verbose = F, progress = F)

Arguments

url	The location of a file.
destdir	Where the file should be downloaded to.
timestamping	Should only newer files be downloaded?
nc	Should files of the same type not be clobbered?
verbose	Should cURL output be shown?
progress	Should a progress bar be shown with cURL output?

Details

If both timestamping and nc are TRUE, nc behavior trumps timestamping.

Value

A character string of the file path to the downloaded file.
