[R] Unable to open html help pages

[Martin McCabe]

I recently upgraded R to 1.9.1 for Mac from 1.8.1.  I am not able to 
open the help pages online but get the message
"If /usr/bin/open is already running, it is *not* restarted, and you 
must switch to its
     window.
Otherwise, be patient ..."
However, nothing happens.  There are not any other windows open to 
switch to and I don't know what /usr/bin/open is!  I'm using an eMac.  
I know the 1.9.1 download is only supposed to be for a PowerMac or 
PowerBook but 1.8.1 seemed to work fine on my eMac (before I downloaded 
1.9.1 and deleted it!).  Is there anything I can do to open html.help?
