[ESS] can I make R help buffers automatically active and maximised?

[Dan Davison]

When I call up a help page in an iESS (*R*) buffer with e.g.

?read.table

the window splits in two horizontally with the requested help page in the other buffer, 
and my cursor stays in the iESS buffer.

Can I control this behaviour? Personally I'd prefer to have the help buffer as the active buffer,
and have that buffer maximised rather than horizontal-split. i.e. I'd like to avoid typing the 
extra C-X o C-x 1.

Thanks,

Dan
