plot.triSht: Plot a triangulation object

In interp: Interpolation Methods

Plot a triangulation object

Description

plots the triangulation object "x"

Usage

## S3 method for class 'triSht'
plot(x, add = FALSE, xlim = range(x$x),
  ylim = range(x$y), do.points = TRUE, do.labels = FALSE, isometric = TRUE,
  do.circumcircles = FALSE, segment.lty = "dashed", circle.lty =
  "dotted", ...)

Arguments

x	object of class "triSht"
add	logical, if TRUE, add to a current plot.
do.points	logical, indicates if points should be plotted. (default TRUE)
do.labels	logical, indicates if points should be labelled. (default FALSE)
xlim, ylim	x/y ranges for plot
isometric	generate an isometric plot (default TRUE)
do.circumcircles	logical, indicates if circumcircles should be plotted (default FALSE)
segment.lty	line type for triangulation segments
circle.lty	line type for circumcircles
...	additional plot parameters

Value

None

Examples

## random points
plot(tri.mesh(rpois(100,lambda=20),rpois(100,lambda=20),duplicate="remove"))
## use a part of the quakes data set:
data(quakes)
quakes.part<-quakes[(quakes[,1]<=-10.78 & quakes[,1]>=-19.4 &
                     quakes[,2]<=182.29 & quakes[,2]>=165.77),]
quakes.tri<-tri.mesh(quakes.part$lon, quakes.part$lat, duplicate="remove")
plot(quakes.tri)
## use the whole quakes data set
## (will not work with standard memory settings, hence commented out)
## plot(tri.mesh(quakes$lon, quakes$lat, duplicate="remove"), do.points=F)
