Brian,

open will call whatever program is defined for a certain extension. You can set this with a plug in to System Preferences called Default Apps for example.

So on my Mac(s) Firefox is the default.

If firefox is involved on a Mac, that is one difference. My Mac is using 'open' (the default, I believe) and that is calling Safari (the default, I believe).

Yes, it would be the job of browseURL to encode URLs where required. But at least on Windows and using the -remoteURL mechanism (as on Linux) it is not. R itself does have URLencode.

As Prof. Ripley noted, try using debug(RSiteSearch) and then step
through the code to see where $HOME is being added to the URL variable. That can help pin it down further. If the URL is not corrupted by the time browseURL() is called, then use debug(browseURL) to trace within
that function to see if something is happening there.
