In MiguelRodo/alwaysloaded: Add desired .Rprofile settings

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>",
  fig.path = "man/figures/README-",
  out.width = "100%",
  eval = FALSE
)

alwaysloaded

The goal of alwaysloaded is to attach frequently-used packages and custom R functions and set desired R options. By placing these in a package rather than in a system- or user-wide .Rprofile file, these can easily be placed into any project-specific .Rprofile files and automatically updated whenever alwaysloaded is changed and re-installed.

Installation

You can install alwaysloaded from GitHub with:

if (!requireNamespace("remotes", quietly = TRUE)) install.packages("remotes")
remotes::install_github("MiguelRodo/alwaysloaded")

Usage

Loading standard options via .RProfile

The primary function is run_std(). Adding the code below to .RProfile (access this easily using usethis::edit_r_profile())) will ensure that standard actions are performed each time R is loaded, without causing unnecessary issues if alwaysloaded isn't installed:

if (interactive()) {
  if (!requireNamespace("alwaysloaded", quietly = TRUE)) {
    if ("renv:shims" %in% search()) {
      install_pkg <- renv::install
    } else {
      if (!requireNamespace("remotes", quietly = TRUE)) {
        try(utils::install.packages("remotes"))
      }
      install_pkg <- remotes::install_github
    }
    install_pkg("MiguelRodo/alwaysloaded")
    rm("install_pkg")
  } 
  try(alwaysloaded::run_std())
  try(library(alwaysloaded))
}

run_std()

R options

• Sets the CRAN repository to https://cloud.r-project.org.

• If the IDE is VS Code, then see alwaysloaded::add_options_vsc for the (many) options set there.
