Hi Petr,
"barp" will compare the two columns displaying the values as heights of
bars.
"stackpoly" will display superimposed polygons, the upper edges of which
represent the data values in each column.
"twoord.plot" will dislay two data vectors as point/line plots even if
they have different ranges.
All are in the plotrix package.
