R: Plot a triangulation object

plot.triSht {interp} | R Documentation

## 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

### 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)
