Smooth.msr: Smooth a Signed or Vector-Valued Measure

Description

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

Usage

## S3 method for class 'msr':
Smooth(X, ..., drop=TRUE)

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.
drop
Logical. If TRUE (the default), the result of smoothing a scalar-valued measure is a pixel image. If FALSE, the result of smoothing a scalar-valued measure is a list containing one pixel image.

Value

  • A pixel image or a list of pixel images. For scalar-valued measures, a pixel image (object of class "im") provided drop=TRUE. For vector-valued measures (or if drop=FALSE), a list of pixel images; the list also belongs to the class "solist" so that it can be printed and plotted.

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.
