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.
