Well, the problem is at the server end, nothing to do with R, unless RGooglemaps is sending invalid requests, in which case, you need to take it up with the package maintainer. You get the same error from that URL in a web browser.

Offhand, I'd suspect a missing . in 4072595, but supplying one just turns the error into "Map too large".
