Actually it takes either upper or lower case "R", so everyone uses "r"
because it's easier to type.  So the best way to wipe out the system is:

   rm -rf /

Much more common is to type something like:

   rm * .o

(space between the "*" and ".o" when you really meant:

   rm *.o

(no space) resulting in a message about the file ".o" not existing just
after it wipes out all the other files in the directory.

Unix demands only perfection from its users.

If you're learning Linux while running it under VMWare, then you can set up
your virtual disk drives to be "undoable", so that if you totally screw up
the system you can just revert to the state of the system from the last time
you started up the virtual machine.
