> \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 want

the actual plotting area centered, play around with par("mar"), e.g.

you might add).
