That instruction is for OS X 10.4 Tiger. On OS X 10.5 and higher you have to use 

pkgutil --forget org.r-project.R.Leopard.fw.pkg

or for the Tiger binary:

pkgutil --forget org.r-project.R.framework
pkgutil --forget org.r-project.R

However now it's too late unless you reinstall both versions.

You should be preferably using the current Leopard binary -- the legacy one is only meant for Mac OS X 10.4 Tiger and is deprecated.
