installr (version 0.23.4)

install.URL: Downloads and runs a .exe installer file for some software from a URL

Description

Gets a character with a link to an installer file, downloads it, runs it, and then erases it.

Usage

install.URL(
  exe_URL,
  keep_install_file = FALSE,
  wait = TRUE,
  download_dir = tempdir(),
  message = TRUE,
  installer_option = NULL,
  download_fun = download.file,
  ...
)

Value

invisible(TRUE/FALSE) - was the installation successful or not. (this is based on the output of shell of running the command being either 0 or 1/2. 0 means the file was successfully installed, while 1 or 2 means there was a failure in running the installer.)

Arguments

exe_URL

A character with a link to an installer file (with the .exe file extension)

keep_install_file

If TRUE - the installer file will not be erased after it is downloaded and run.

wait

should the R interpreter wait for the command to finish? The default is to NOT wait.

download_dir

A character of the directory into which to download the file. (default is tempdir())

message

boolean. Should a message on the file be printed or not (default is TRUE)

installer_option

A character of the command line arguments

download_fun

a function to use for downloading. Default is download.file. We can also use curl_download (but it doesn't give as good of an output while downloading the file).

...

parameters passed to 'shell'

Details

This function is used by many functions in the installr package. The .exe file is downloaded into a temporary directory, where it is erased after installation has started (by default - though this can be changed)
