Yes, simply define a hook function for figure chunks: The effect of

options(SweaveHooks=list(fig=function() par(bg="red", fg="blue")))


should be easy to see :-) The hook function will be executed at the
beginning of each chunk where fig=true (i.e., all figure chunks).


What you want is something like

options(SweaveHooks=list(fig=function() par(mar=c(1,2,3,4))))


Hope this helps,
