R Documentation

Plot Point Pattern on Linear Network

Description

Plots a point pattern on a linear network. Plot method for the class "lpp" of point patterns on a linear network.

Usage

## S3 method for class 'lpp'
plot(x, ..., main, add = FALSE,
                   use.marks=TRUE, which.marks=NULL,
                   show.all = !add, do.plot = TRUE, multiplot=TRUE)

Arguments

`x`	Point pattern on a linear network (object of class `"lpp"`).
`...`	Additional arguments passed to `plot.linnet` or `plot.ppp`.
`main`	Main title for plot.
`add`	Logical value indicating whether the plot is to be added to the existing plot (`add=TRUE`) or whether a new plot should be initialised (`add=FALSE`, the default).
`use.marks`	logical flag; if `TRUE`, plot points using a different plotting symbol for each mark; if `FALSE`, only the locations of the points will be plotted, using `points()`.
`which.marks`	Index determining which column of marks to use, if the marks of `x` are a data frame. A character or integer vector identifying one or more columns of marks. If `add=FALSE` then the default is to plot all columns of marks, in a series of separate plots. If `add=TRUE` then only one column of marks can be plotted, and the default is `which.marks=1` indicating the first column of marks.
`show.all`	Logical value indicating whether to plot everything including the main title and the observation window of `x`.
`do.plot`	Logical value determining whether to actually perform the plotting.
`multiplot`	Logical value giving permission to display multiple plots.

Details

The linear network is plotted by plot.linnet, then the points are plotted by plot.ppp.

Commonly-used arguments include:

col and lwd for the colour and width of lines in the linear network
cols for the colour or colours of the points
chars for the plot characters representing different types of points
legend and leg.side to control the graphics legend
show.window=FALSE to suppress the box drawn around the linear network.

Value

(Invisible) object of class "symbolmap" giving the correspondence between mark values and plotting characters.
