Definitely install a package in Rstudio

Question

I have to reinstall all the packages like dplyror ggplot2 each time that I restart Rstudio.

Do you have any suggestion for setting once and for all my packages in Rstudio?

Do you have to really reinstall them? Or does just loading them with e.g. library(ggplot2) suffice? — Jaap
Yes, I had to reinstall each time. Finally, I created a R.profile file for each project, and I put a R script for automatically installing packages when I load the project. — KKc

You could either have a script that runs:

packages <- c("plyr", "ftnonpar")
install.packages(packages)

Where you would just add entries for each package in packages, and run the script each time you open.

However, it might just be that you are not calling the packages each time you restart Rstudio and need to use:

library(<package_name>)

For each package you intend to use at the top of your script.
