plot.recurse {recurse}

Calculates recursion information from the trajectory

Description

Plots a trajectory color coded by number of revisits to each point.

Usage

## S3 method for class 'recurse'
plot(x, xyt, ..., col, alpha = 1, legendPos = NULL)

Arguments

x

recurse object returned from call to getRecursions

xyt

data.frame of x, y, t, and id representing the xy-coordinates and the time (same as call to getRecursions)

...

additional arguments to plot

col

optional vector of colors as long as the maximum number of revisits to color code trajectory points

alpha

optional alpha value for color transparency between 0 and 1

legendPos

a vector of length 2 with the x and y coordinate of the center of the legend in user coordinates

Details

This method allows the user to visually represent the number of revisitations by location. The size of the circle of radius R can be added to the plot with drawCircle.

Value

the plot
