mauricer demo

Introduction

mauricer is an R package to handle BEAST2 package management from R, similar to the BEAST2 package manager.

The BEAST2 package manager

In this vignette, we will:

• List all BEAST2 packages
• Install the first non-installed BEAST2 package
• Verify the BEAST2 package is indeed installed
• Uninstall the BEAST2 package

To do so, we’ll need to load mauricer. We’ll also load testthat for testing:

library(mauricer)
#> Loading required package: beastier
library(testthat)

To install BEAST2 packages, one needs

• an internet connection
• BEAST2 must be installed

If there is no internet connection, or if BEAST2 is not installed, this vignette will be close to empty.

if (!curl::has_internet()) {
  print("No internet connection")
}
if (!beastier::is_beast2_installed()) {
  print("No BEAST2 installed")
}

List all BEAST2 packages

Use get_beast2_pkg_names to get a data frame with the name, version and install status of all BEAST2 packages:

if (curl::has_internet() && beastier::is_beast2_installed()) {
  beast2_packages <- get_beast2_pkg_names()
  knitr::kable(head(beast2_packages))
}

Install the first non-installed BEAST2 package

Find a package that is not installed:

if (curl::has_internet() && beastier::is_beast2_installed()) {
  package_name <- beast2_packages[
    beast2_packages$installed_version == "NA",
  ]$name[1]
  print(package_name)
}
#> [1] "Babel"

Install that package:

if (curl::has_internet() && beastier::is_beast2_installed()) {
  mauricerinstall::install_beast2_pkg(package_name)
}

Note that this installation uses a non-CRAN package, called mauricerinstall, as installing software is against CRAN policy.

Uninstall the BEAST2 package

Use uninstall_beast2_pkg:

if (curl::has_internet() && beastier::is_beast2_installed()) {
  mauricerinstall::uninstall_beast2_pkg(package_name)
}

Also this code uses a non-CRAN package, called mauricerinstall, as installing software is against CRAN policy.
