convert Map shapes to logical matrices - for set operations
Hi, I have a little problem.
I'm trying to do the following:
Convert _projected_ shapes from a Map object into logical matrices.
That is, rasterize a shape into a logical "in-the-shape" and
"out-of-the-shape" matrix.
What I'm trying to do is get an 'equal-area' estimate of the area of

3 | 8.5 | 10 | 12
I need to produce some graphs typifying the change for each group
between a _projected_ final reading and the final reading given. The
time difference between previousavg and lastreading is 1/2 that between
lastreading and finalreading.
Where I have got to so far:
I have read the result set (less than 200 rows) into a table 'results',
attached it and then rather crudely cons...
