changeData              Creates a list containing the raster data sets
                        concerning the number of times the category of
                        interest is present and the number of times the
                        category of interest changes during the time
                        series.
dataStack               Creates results that serve as input for the
                        stackbarPlot function.
presencePlot            Creates two maps: a map showing how many times
                        the category is present during the time series
                        and a map showing how many times the category
                        changes during the time series.
stackbarPlots           Create stack bar plots showing trajectories
                        sizes and the three change components.
trajData                creates the data which serves as input for the
                        "trajPlot" function.
trajPlot                Creates a map and pie chart of the trajectories
                        of the category of interest.
