Calculates recursion information from the trajectory

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

# S3 method for 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

Value

the plot

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.

Examples

data(martin)
revisits = getRecursions(martin, radius = 1)
plot(revisits, martin, legendPos = c(10, -15))
drawCircle(10, -10, 1)
