intersectPolyCircle: Intersection of a Polygonal and a Circular Domain

In surveillance: Temporal and Spatio-Temporal Modeling and Monitoring of Epidemic Phenomena

Intersection of a Polygonal and a Circular Domain

Description

This is a unifying wrapper around functionality of various packages dealing with spatial data. It computes the intersection of a circular domain and a polygonal domain (whose class defines the specific method).

Currently the only supported class is "owin" from package spatstat.geom.

Usage

intersectPolyCircle(object, center, radius, ...)

## S3 method for class 'owin'
intersectPolyCircle(object, center, radius, npoly = 32, ...)

Arguments

object	a polygonal domain of one of the supported classes.
center,radius,npoly	see discpoly.
...	potential further arguments (from the generic).

Value

a polygonal domain of the same class as the input object.

plot(letterR)
plot(intersectPolyCircle(letterR, c(3,2), 1), add=TRUE, col=2, lwd=3)
