Compute x,y Coordinates From Hexagon Cell Ids
DESCRIPTION:
Computes x and y coordinates from hexagonal cell indices.
USAGE: 
cell2xy(bin)
REQUIRED ARGUMENTS:
bin:
an object of class "hexbin".
VALUE:
a data frame with components x and y containing the cartesian coordinates corresponding to the centers of the hexagonal bins described in bin.
DETAILS:
The bin object contains all the information that is usually needed. This function reduces storage by allowing the user to call it whenever the lattice center coordinates are needed. To plot the hexagonal centers use plot(as.list(cell2xy(bin))).
