smooth.msr {spatstat}R Documentation

Smooth a Signed or Vector-Valued Measure

Description

Apply kernel smoothing to a signed measure or vector-valued measure.

Usage

 smooth.msr(X, ...)

Arguments

X

Object of class "msr" representing a signed measure or vector-valued measure.

...

Arguments passed to density.ppp controlling the smoothing bandwidth and the pixel resolution.

Details

This function applies kernel smoothing to a signed measure or vector-valued measure X. The Gaussian kernel is used.

The object X would typically have been created by residuals.ppm or msr.

Value

For signed measures, a pixel image (object of class "im"). For vector-valued measures, a list of pixel images; the list also belongs to the class "listof" so that it can be printed and plotted.
