Get frequencies for a 2D histogram

Description

?

Usage

hist2d(x, y = NA, nbins = c(25, 25), edges = NA)

Arguments

nbins	A numeric vector with two integers: the number of bins for X and for Y coordinates, defaults to c(25, 25).
edges	A list with the edges for the X and Y coordinates respectively. This allows irregular bin sizes. Note that the number of edges is the number of bins plus 1. If 'edges' is given it overrides 'nbins'.
X	Vector of X-coordinates, or a Mx2 matrix with M sets of X and Y coordinates, or data frame with x and y column.
Y	If X is not a matrix or data frame, but a vector this has to be a vector of equal length with Y coordinates.

Details

Value

A list with three entries: - 'freq2D' numeric matrix with counts for each bin - 'x.edges' numeric vector with the edges used for x coordinates - 'y.edges' numeric vector with the edges used for y coordinates
