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

On unix systems it is usually a different environment variable. What it is exactly varies by unix system and shell. R.libPaths 1 '/usr/local/lib/R/site-library' '/usr/lib/R/site-library' 3 '/usr/lib/R/library' R meaning that the default path is the first of these. You can override that via an argument to both install.packages (from inside R) or R CMD INSTALL (outside R). You can also override by setting the RLIBSUSER variable. Background: Mac OS X 10.11 introduced System Integrity Protection, which treats parts of the filesystem specially to prevent tampering with the system. Among those protections is that executables in /bin, such as /bin/sh, have the DYLDLIBRARYPATH variable. Nov 01, 2017 The new R version appear right after I install R and restart RStudio. Update: For Mac users, solution 3 is too painful and not working well for me. This method is fast and working well.
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.
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.

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
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()
You can find the tutorial on how to use installr to update RStudio on R-Statistics website.
Solution 3) Mac only – use updateR
Similar to installr, updateR is the package to help updating R on Mac OS.
The R code you will need is these 5 lines: (credit goes to jroberayalas for the code)
R Library Path Machine
install.packages('devtools') #assuming it is not already installed
library(devtools)
install_github('andreacirilloac/updateR')
library(updateR)
updateR(admin_password = 'Admin user password')
You can find in-depth tutorial on how to use updateR package on this blog.
How to move the previously installed R packages
Ld Path
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
Can't See Library Folder Mac
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
Mar 18, 2020 Follow these steps to use the Photos library repair tool: Hold down the Option and Command keys while you open Photos on your Mac. In the dialog that appears, click Repair to start the repair. If it’s a permissions problem, Photos.app doesn’t like to ask for administrator privileges automatically, instead just saying that Photos attempted to repair the library but is unable to open it without actually trying to repair it. You can force Photos to try to repair the library by holding ⌥option and ⌘command whilst launching Photos. Photos.app will try to repair the library and it may ask you for administrator. Nov 10, 2019 Launch Photos and run the repair tool again. If the repair tool still fails, you still have all those image files copied to a new location. Jun 16, 2016 1 - launch Photos with the Option key held down and create a new library. 2 - open your old library package with the Finder as shown in this screenshot: 3 - locate the Master folder in the old library and drag it onto the Photos icon in the Dock. This will create a new library with the same Moments as the original library but will not include the metadata, albums, books slideshows and other projects. Mac photos library repair fail. Jul 26, 2018 Apparently Apple has seen this happen before, because the company has a hidden Photos library repair tool. Here’s how you can use it to fix issues with Photos, including a library refusing to open or showing errors when copying.
