Hi

I would like to have a plot layout, on which line graphs are on the plot
area of an underlying bar graph.
How can I achieve this? I know about layout() and par() to create a
layout, but as far as I know, they assign non-overlapping plot areas.

Sorry - did not do my homework and forgot to google - found the solution
(http://tolstoy.newcastle.edu.au/R/help/04/11/6449.html).

But an additional question - uis there a way to position the plots in
relation to the co-ordinates of the first plot, i.e. the x axis of the
first plot (ehich covers the whole plot area) is from 1 to 6 - can I
position the second overlapping plot over the x-coordinate 3 of the
first plot?

Effectively, it should look as below:
