[R] saving multiple panes to PNG

[Jannis]

Do you want the stuff to appear on one page? Have you tried opening a 
device with multiple plots? For example via:

par(mfrow=c(2,2))

or:

layout(matrix(1:4,2,2))



Other than that the documentation for the "vars" package gives you 
details for a plot function that may be used for plotting your irf 
objects. There is an argument (plot.type) that can be set to plot 
multiple plots on one page.
