# 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 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.
