There are a number of ways to do this in R; some pointers to get you
(i) par(new=TRUE) allows you to overlay several plots on the same page
(ii) par(fig) and par(plt) provide fine control over where a plot
appears on a page
(iii) accurately locating subplots within a bigger plot may require some
conversions between coordinate systems; par("usr"), par("plt"), ... can
be used to obtain information on current coordinate systems
(iv) you can have all the transformations done for you, by using the
grid package to create viewports and the gridBase package to align them
with a bigger plot - see the recent R News article "Integrating grid
Graphics Output with Base Graphics Output"
