Chris Hamm on using plot.new() for better combined plots

# plot.new() cahamm@ucdavis.edu

#I discovered this plotting method when trying to add an inset figure
# to a plot

# plot.new is part of the traditional graphics. This function starts a new plot with the
# scale of the x- and y- axes to (0,1) This allows you to specify the location of each
# pane or inset and provides a high level of customizability for R graphics
