Updating R Version Without missing packages

After updating to new R version (4.5) from old version, you have to re-install all packages by default. However, there’re some solution for that.

Unix (MacOs, Linux)

1.Create a new folder in home directory to store the packages. Sometimes, you need to change the permission level for this folder, or R may not have access to write this folder. Rlibs is a special folder where you can store all you packages.

sudo mkdir ~/Rlibs

2.Edit the .Reviron file in your home directory ("~") (create a new file if you don’t have it). Add the code below to let R know where is the installed Packages. R will read the configuration in the background from the path “~/.Reviron”.

R_LIBS=~/Rlibs

3.Re-install you packages. After that you shall see your packages are stored in Rlibs folder.

My research interests mainly focus on the Bayesian Diagnostic Classification Models (DCMs) - a special kind of Item Response Model and the model checking method, as applied in the psychological, educational, and social sciences. I seek to improve the utility of advanced psychometric modeling and provide easy-to-use tools or software for researchers.
