Interval level intensity analysis
1 | IIA(crosstabulation, time.points)
|
crosstabulation |
List of crosstabulation tables generated by |
time.points |
a charachter vector showing the time point of each raster layer in chronological order. |
Gets the list of crosstabulation tables, time points vector and returns a list of interval level metrics accompanied with relevant bar graphs.
The output is a list of lists. Elements of the list include: change amount, uniform intensity of change and Uniform change all in all intervals.
