[R] changing figure size in Sweave

[Robin Hankin]

Hi

In Sweave, how does one change the size of the plots?

I tried using a hook:


<<echo=FALSE, print=FALSE, fig=TRUE>>=
options(SweaveHooks=list(fig=function() ps.options(width=1)))
library(graphics)
pairs(iris)
@

but this didn't change the size of the figure.  How to make the  
figures a
different size?
