\setkeys{Gin}{width=8} gets the desired width but shifts the graph to the right. Is there another latex command to place the graph so that the margins on left and right of the page are the same? \centering or \begin{center} doesn't seem to get it right. I have about one inch margin to my right and about 2.5 inches to my left.

Remember that by default R doesn't put symmetric margins around plots.Latex will center the whole plot, including white space. If you wantthe actual plotting area centered, play around with par("mar"), e.g.


par(mar=c(4,4,4,4)+0.1)

for fat margins,

par(mar=c(2,2,2,2)+0.1)

for thin ones (which probably don't have enough room for all the labelsyou might add).

"normal sized" graph that starts in the second

the pdflatex wrapper

>>There are two ways to control the size of an Sweave graph:by telling R the size you want, and by telling LaTeX how big

to make it when you include it.

You tell R the size by using <<fig=true, width=w,
height=h>>= (with w and h being numbers in units of
inches).  You tell LaTeX
(assuming you're using the graphicx package) by using
\setkeys{Gin}{width=w} (or maybe you'd want to set
the height, but I usually just set the width and
let LaTeX scale the height accordingly).  The w here is a
LaTeX measure such as \textwidth or 4in or whatever you
like.

I find the font choices in R look a little bit too large if
I tell R the actual size I want, so I generally use both:
tell R I want the figure larger than I really want it, and
then tell
LaTeX to shrink it to fit.
