?tiff
?capabilities

Use the tiff device and specify the size you want. I'm assuming that  
those units were in inches for your situation.

Modified from the help page:

 > tiff(file="myplot.tif", bg="transparent", width=12, height=17,  
units="in", res=150)
 > plot(1:10); rect(1, 5, 3, 7, col="white")
 > dev.off()

(On my machine capabilities() tells me that I don't have a tiff device  
but experimentations suggests that information may not be entirely  
correct.)
