Install or Update the ASReml-R package — install

Helper functions for installing or updating the ASReml-R package, intended to reduce the difficulty of finding the correct version for your operating system and R version.

Usage

install_asreml(
  library = .libPaths()[1],
  quiet = FALSE,
  force = FALSE,
  keep_file = FALSE
)

update_asreml(...)

Arguments

library: Library location to install ASReml-R. Uses first option in .libPaths() by default.
quiet: Logical (default FALSE). Should package be installed quietly?
force: Logical (default FALSE). Force ASReml-R to install. Useful for upgrading if it is already installed.
keep_file: Should the downloaded asreml package file be kept? Default is FALSE. TRUE downloads to current directory. A file path can also be provided to save to another directory. See Details for more information.
...: other arguments passed to install_asreml()

Value

Silently returns TRUE if asreml installed successfully or already present, FALSE otherwise. Optionally prints a confirmation message on success.

Details

The ASReml-R package file is downloaded from a shortlink, and if keep_file is TRUE, the package archive file will be saved in the current directory. If a valid path is provided in keep_file, the file will be saved to that path, but directory is assumed to exist and will not be created. If keep_file does not specify an existing, valid path, an error will be shown.

Examples

if (FALSE) {
# Example 1: download and install asreml
install_asreml()

# Example 2: install asreml and save file for later
install_asreml(keep_file = TRUE)
}
