Creates a list of hexbin objects. Basic components are
a cell id and a count of points falling in each occupied cell.
Basic methods are show(), plot()
and summary(), but also erode.
hexList(x, y = NULL, given = NULL, xbins = 30, shape = 1,
xbnds = NULL, ybnds = NULL, xlab = NULL, ylab = NULL)x coordinate to be binned
y coordinate to be binned
..
number of bins partitioning the range of xbnds
the shape = yheight/xwidth of the plotting regions
horizontal limits of binning
vertical limits of binning
character strings used as labels for x
character strings used as labels for y
If it is a LIST, use
Description of 'comp1'
Description of 'comp2'
There is also a coerce method to produce
hexbinList objects from lists.
