Hi Ben,

Use the :width and :height header args to alter the dimensions of the
graphics. The arguments go straight through to the R device, so if you
are plotting to pdf they will be interpreted as inches (whereas they
will be pixels for png, jpeg etc).

With current Org, you will also need :results graphics in order to tell
R to send graphics to the designated file.

In addition, with lattice graphics, unless you are using :session, I
believe you will need :results output (so :results output graphics).

Do get back to us with any problems. There are several people who
routinely use R to include graphics in Org documents.

Dan

p.s. Request to everyone: can we try as much as possible to use
reproducible examples on-list?  I.e. toy examples that anyone can
execute, instead of real examples that rely on datasets that not
everyone has access to.
