R help - Nov 2004 - Error when scan()ning dead URL's

Hi,

I often scan web pages directly into R using

scan('http://etc...','')

however this gives an error if the page/url doesn't exist, or the connection
to it is not available.
Is it possible to still use scan but have R return something other than an
error (which crashes code)
when the page or the connection isn't available.

Cheers

John Haynes

Can't you just wrap it in a try() construct?
