Subject: [R] two connected graphs

Hi

I have two datasets, A and B, consisting of two columns of numbers
representing x and y coordinates.

They have 10 and 6 rows respectively.

I want to plot two scattergraphs, one above the other.

The lower graph to contain A (10 points) and the upper graph to contain
B (six points).

The x-axes of the two graphs must line up.

I then want to draw straight lines that connect points of  B to a
particular point (or points)  of A.

How do I do this?
