download_file: Download file from GitHub via the proxy site

Description

This function can be used to download a file from GitHub via the proxy website <https://gh-proxy.com/> or <https://ghfast.top/>.

Usage

download_file(
  url,
  destfile,
  method,
  quiet = FALSE,
  mode = "w",
  cacheOK = TRUE,
  extra = getOption("download.file.extra"),
  headers = NULL
)

Arguments

url

a character string (or longer vector for the "libcurl" method) naming the URL of a resource to be downloaded.

destfile

a character string (or vector, see the url argument) with the file path where the downloaded file is to be saved. Tilde-expansion is performed.

method

Method to be used for downloading files. Current download methods are "internal", "libcurl", "wget", "curl" and "wininet" (Windows only), and there is a value "auto": see ‘Details’ and ‘Note’. The method can also be set through the option "download.file.method": see options().

quiet

If TRUE, suppress status messages (if any), and the progress bar.

mode

character. The mode with which to write the file. Useful values are "w", "wb" (binary), "a" (append) and "ab". Not used for methods "wget" and "curl". See also ‘Details’, notably about using "wb" for Windows.

cacheOK

logical. Is a server-side cached value acceptable?

extra

character vector of additional command-line arguments for the "wget" and "curl" methods.

headers

named character vector of additional HTTP headers to use in HTTP[S] requests. It is ignored for non-HTTP[S] URLs. The User-Agent header taken from the HTTPUserAgent option (see options) is automatically used as the first header.
