The plotBursts
function plots bursted Move objects (see ?burst for how to create a bursted Move Object). For every single burst a circle is plotted at the center of every segment of a track. A segment represents consecutive coordinates that belong to a single burst. The properties of the plotted circles (size and color) can represent different information (see Details).

|
object |
a SpatialPointsDataFrame or a list of these that include coordinates and color, and size of the centroid indicators |
add |
logical, if FALSE a new plot is generated, default is TRUE |
sizeFUN |
a function to calculate the size of the plotted circles (see details) |
breaks |
how many size classes should the circles have, default is 3 |
col |
a vector of color codes with the same length as the burstID. By default the standard colors from 1:8 are used. If there are more than 8 burstIDs the colors are recycled |
... |
additional plot attributes |
Circle colors correspond to burstIDs. The size of the circles is defined by a function. By default this function calculates the relative duration of a segment compared to the whole duration. The function can be adjusted to use a different measure using the sizeFUN
argument.
Note, it is possible to define break points by using the breaks
argument.
