63_probability_matrices: Bivariate Density/etc Matrices

In probhat: Multivariate Generalized Kernel Smoothing and Related Statistical Methods

Description

Convenience function to construct an S4 object representing a bivariate density/etc matrix from a bivariate PDF/CDF.

Unlike other objects in the package, you're welcome to access the slots.

Usage

ph4.BVMatrix (sf, xlim, ylim, ..., n=10)

Arguments

sf	A suitable function object. (Here, this refers to a bivariate PDF/CDF).
xlim, ylim	Numeric length two vectors, giving the evaluation ranges.
n	Integer vector of length one or two, giving the number of points, in each x and y direction.
...	Ignored.

Value

An S4 object with three slots, fv (a matrix), x (x evaluation points) and y (y evaluation points).

Each row in fv, corresponds to one x value, and each column to one y value.
