Suppose I have some MathType that looks like:
((x1, x2, ... xn) -> (y1, y2, ... yn))
How should I create a subset of this data where one of the x's or y's
falls within some range?
For instance, I might have a data set like:
((lat, lon) -> (elevation, temperature, precipitation, NDVI))
and I might want to bin this data by elevation in order to demonstrate
something about microclimates on a mountainside.
