The macos_rtools_install() function aims to install all required dependencies for the macOS R compilation toolchain. Meanwhile, the macros_rtools_uninstall() function aims to remove any installed files from your computer.

Usage

macos_rtools_install(
  password = getOption("macrtools.password"),
  verbose = TRUE
)

macos_rtools_uninstall(
  password = getOption("macrtools.password"),
  verbose = TRUE
)

Arguments

password

Password for user account to request sudo access.

verbose

Details

The macOS R compilation toolchain consists of:

1. Xcode CLI

2. gfortran

3. A series of binary packages from the recipes system to compile R.

The mac_rtools_install() function attempts to install each of the required components. If we detect that the Xcode.app IDE is installed, we'll skip attempting to install the Xcode CLI software.

Meanwhile, the mac_rtools_uninstall() function aims to delete or uninstall the Xcode CLI and gfortran binaries. At the present moment, there is no support for uninstalling the binary packages from recipes.

Headless or Unattended Installation

For an installation that does not require a human in the loop, please set the environment variable macrtools.password for the user profile:

Sys.setenv("macrtools.password" = "your-password-here")

Examples

if (FALSE) { # \dontrun{

# Install all tools required for compiling code on macOS with R
macos_rtools_install()

# Enter a password to avoid being prompted!
macos_rtools_install(password = "hello-compiled-code-world")

} # }

if (FALSE) { # \dontrun{

# Remove Xcode CLI and gfortran tools required for compiling code on macOS with R
macos_rtools_uninstall()

# Enter a password to avoid being prompted!
macos_rtools_uninstall(password = "hello-compiled-code-world")
