\name{download_file}
\alias{download_file}
\title{Try various methods to download a file}
\usage{
download_file(url, output = url_filename(url), ...)
}
\arguments{
\item{url}{The URL of the file.}
\item{output}{Path to the output file. By default, it is determined by
\code{\link{url_filename}()}.}
\item{...}{Other arguments to be passed to \code{\link{download.file}()}
(except \code{method}).}
}
\value{
The integer code \code{0} for success, or an error if none of the
methods work.
}
\description{
Try all possible methods in \code{\link{download.file}()} (e.g.,
\code{libcurl}, \code{curl}, \code{wget}, and \code{wininet}) and see if any
method can succeed. The reason to enumerate all methods is that sometimes the
default method does not work, e.g.,
