`R-ex' contains the examples from the `man' pages and demo contains the `demo' files. Whereas man pages are necessary to pass R CMD check, demo files are not, so this is part of the reason while much more packages have examples but not demos.

You can conveniently look at both, using examples() and demo() from within R.
