R CMD check: "the site can't be reached" browser tabs

[mattdowle]

Hi,
I'm checking KRIG because it Suggests data.table. When I run R CMD check, at some point in KRIGs tests, tabs are created in my Chrome browser for locations like "http://127.0.0.1:10883/library/KRIG/doc/simple_kriging.html". But the contents of the page is as the image shows :

R CMD check passes though (with just 1 note, which is fine).

Just letting you know really. I don't mind the browser tabs being created at all, but it would be nice to make the "the site can't be reached" error go away and see some graphs or results or something, just to know the package was working.

Best, Matt
