The command-line utility 'wget' can download websites,
including graphics, etc. Look for 'mirror' in its
documentation if you want to download the complete
site. It is usually available by default on Unix-style
systems; I am sure there is a version for Mac. If you
insist on using R, you could write a simple wrapper,
using ?system or ?system2.
