R help - Dec 2003 - passing par() options to pdf under Sweave

I'm using Sweave to generate LaTeX output from R. Thank-you 
very much for this capability. It is very useful.

Could someone please tell me how to pass non-default 
graphics parameters from par() to the pdf driver when it is 
called by Sweave? 

(I need to change some of the margin defaults. )

Hoping there is an easy solution to this question,

Anne York

Sorry for wasting the list for this. Had a blind spot.  It 
is very easy. Just  include the par() commands inside the R 
chunks that generate the plots.

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,
