Load multiple packages at the same time in R

Load-Multiple-R-Packages.R

# library() or require() only load one package at a time
# but...

Packages <- c("dplyr", "ggplot2", "rstan", "readr")

lapply(Packages, library, character.only = TRUE)

# this loads as many as you put in 'Packages'. They need to be installed first, of course.

Thanks. It works for me. Simple and easy

Nice. Wrapping it in invisible() is also convenient :)

perfect!

Awesome, thank you!

If one is too lazy to "".

load_pkg <- rlang::quos(tidyverse, tidylog, lubridate, readxl, janitor, tictoc)

invisible(lapply(lapply(load_pkg, rlang::quo_name),
  library,
  character.only = TRUE
))

@leungi Haha, laziness is always good!

Actually, I use Yihui's xfun package for this now. As per the documentation:

pkg_attach() is a vectorized version of library() over the package argument to attach multiple packages in a single function call.

xfun::pkg_attach(<pkgs>)

Where <pkgs> is character vector of package names. Super lazy :-)

Thanks for tip @RobertMyles 👍

I usually use pacman::p_load(), but just realized during RStudio Connect deployment, it'll attempt to re-install every packages, regardless if it's installed or not!

I checked xfun::pkg_attach(), and it seems it has a check xfun::loadable(), which should avoid the above.

Thanks for the share! much convenient than pacman::
