plot.ltraj: Graphical Display of an Object of Class "ltraj"

Description

plot.ltraj allows various graphical displays of the trajectories.

Usage

## S3 method for class 'ltraj':
plot(x, id = unique(unlist(lapply(x, attr, which = "id"))),
           burst = unlist(lapply(x, attr, which = "burst")), spixdf = NULL,
           spoldf = NULL, xlim = NULL, ylim = NULL, colspixdf =
           gray((240:1)/256), colspoldf = "green",  addpoints = TRUE,
           addlines = TRUE, perani = TRUE, final = TRUE, ...)

Arguments

x

an object of class ltraj

id

a character vector containing the identity of the individuals of interest

burst

a character vector containing the burst levels of interest

spixdf

an object of class SpatialPixelsDataFrame

spoldf

an object of class SpatialPolygons

xlim

the ranges to be encompassed by the x axis

ylim

the ranges to be encompassed by the y axis

colspixdf

a character vector giving the colors of the map spixdf

colspoldf

a character vector giving the colors of the polygon contour map, when spoldf is not NULL

addpoints

logical. If TRUE, points corresponding to each relocation are drawn

addlines

logical. If TRUE, points corresponding to each relocation are drawn

perani

logical. If TRUE, one plot is drawn for each value of id, and the several bursts are superposed on the same plot for a given animal. If FALSE, one plot is drawn for each value of burst

final

logical. If TRUE, the initial and final relocations of each burst are indicated in blue and red, respectively

...

arguments to be passed to the generic function plot
