On a Mac, the R scripts from installed packages are typically stored in the "library" folder. Specifically, they are located in the "site-library" subfolder within the main library folder for R. The location of the library folder may vary depending on your system configuration, but it is typically found in the following directory:

/Library/Frameworks/R.framework/Versions/<version>/Resources/library/
