how to start R64 from M-x R...

Hi there,

May be this question has been answered before, but how to start the  
64 bit version inside ESS? I have successfully used
C-u M-x R then "--arch=x86_64" <RT>, but remembering "--arch=x86_64"  
is a nuisance (for me...).
Defining on Unix >  alias R64 'R --arch=x86_64 &' works only from  
the terminal, so obviously this is an ESS thing (with elisp?) which  
I am not versed in.

You may ask on the ESS list, but another way around is to change the default directly in the R start script by changing
: ${R_ARCH=/`arch`}
to
: ${R_ARCH=/x86_64}
