Yes!! That is the one baby patch I contributed to R -- I once needed wget
because it get around a particular firewall I was behind. So see

	help(download.file)

where argument method can be set as 

  method: Method to be used for downloading files.  Currently download
          methods '"internal"', '"wget"' and '"lynx"' are available,
          and there is a value '"auto"': see Details.  The method can
          also be set through the option '"download.file.method"': see
          'options()'.

AFAICR wget will still re-download a file foo.bar if present and simply call
it foo.bar.1 but there must be an option to make it stop....

That's one view, the other is that bad / empirical programmers like myself
like to restart from the beginning but are too impatient to re-download the
save few megabytes over and over and over :)
