In biometryassist: Functions to Assist Design and Analysis of Agronomic Experiments

Install or update the ASReml-R package

Description

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()

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 all directories are assumed to exist and will not be created. If keep_file does not specify an existing, valid path, an error will be shown after package installation.

Value

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

Examples

# Example 1: download and install asreml

# Example 2: install asreml and save file for later
