What is a R file?

Files that contain the .r file extension are most commonly associated with the Mac OS X operating system.

The R files that are used by the Mac OS system contain resource files that are referenced by applications which are run in the Mac OS X environment. These files store the shortcut functions and variable definitions for the associated software applications.

The RatFor Fortran software application has also been known to use the .r file suffix. These R files contain pre-processor source files that are created within the RatFor Fortran program.

The popular Pegasus Mail email application also uses the .r file extension. These R files contain resource files that are references by the email program.
