How To R Studio On Mac

When was the last time you update your R and RStudio?

I installed RStudio and R a year ago, and never update it since then. Today I just noticed I cannot install new R packages because of my old R version. So I explore some ways to update R and would like to share with someone who is also looking to update R on RStudio.

How to Install R and R Studio MAC Users Version Fall 2019 R is a free software for statistical computing and graphics. Its learning curve is a bit steep. But, fortunately for us, there also exists R-Studio. R-Studio is a user interface that allows the user to run R in an environment that is much more friendly, especially for new users.

  1. Of course to check what your R Studio version is you just need to click on the Help menu item and then click on “About RStudio”. To update R, go to CRAN and download the latest version and run the install. When you restart RStudio or R Console it should automagically detect and use the new R version.
  2. Go to this website. If your mac is OS X 10.11 and higher (this should be the case for most of you), click the R-3.5.1.pkg link. If your mac is OS X 10.9 or 10.10, click the R-3.3.3.pkg link. After clicking on the link, the file (package installer) will be downloaded onto your computer.

The problem

RStudio and R cannot update on their own because some packages may not work after switching to the new version (You can still downgrade R version in RStudio if something went wrong though). After you install the new version, the previously installed packages will not go to next version. So it is required extra procedures to move the packages.

Here are 3 ways you can update R version in RStudio. Note that we need to move the install R packages, which I will show how at the end.

3 Solutions to update R on RStudio

Solution 1) Manually install (Recommended if you don't care about the old packages)

The first method is to download a new version of R from R website > CRAN. Then restart your RStudio. The new R version will be loaded automatically.

Download R-studio Windows

The new R version appear right after I install R and restart RStudio

Update 29/05/2019: For Mac users, solution 3 is too painful and not working well for me. This method is fast and working well. I would recommend to save your time from headache and use this method. Take note of your previous packages so you can install them again as needed.

Solution 2) Windows only – use installr

Mac

installr is the R package which helps install and update software.

The R code you will need for updating R is: (credit goes to Cara Wogsland for the code)

install.packages('installr')

library(installr)

updateR()

install.packages('devtools') #assuming it is not already installed

library(devtools)

library(updateR)

How to move the previously installed R packages

This is the instructions for Mac OS user (who used solution 1 or 3 above). For Windows user, installr package will do this for you

(credit goes to RyanStochastic and micstr):

1. Move all folders from your old R version to new R version.

/Library/Frameworks/R.framework/Versions/x.xx/Resources/library

Replace x.xx with the old and new R version at a time.

Note that you have to move only the packages that are not currently in the destination folder (because those are the base packages, and you don’t want to ruin them). But if you already did replaced everything, the next step will solve this for you.

If you cannot find the proper path, you can run this command to check: installed.packages()

2. Update the moved packages

Run the following command in R. Type ‘y’ for every question that popped up.

update.packages(checkBuilt=TRUE)

3. Type the following command in R to check if everything went well
