ThreeMapComparison: Evaluate allocation performance with three maps
In simonmoulds/lulcc2: Land Use Change Modelling in R

Description Usage Arguments Value References See Also Examples

An implementation of the method described by Pontius et al. (2011), which compares a reference map at time 1, a reference map at time 2 and a simulated map at time 2 to evaluate allocation performance at multiple resolutions while taking into account persistence. The method quantifies disagreement within coarse squares (minor allocation disagreement), disagreement between coarse squares (major allocation disagreement), disagreement about the quantity of land use change and agreement.

ThreeMapComparison(x, x1, y1, ...)

## S4 method for signature 'RasterLayer,RasterLayer,RasterLayer'
ThreeMapComparison(x, x1,
  y1, factors, categories, labels, ...)

`x`	either a RasterLayer of observed land use at time 0 or an object inheriting from class `Model`
`x1`	a RasterLayer of observed land use at a subsequent time. Only required if `x` is also a RasterLayer
`y1`	a RasterLayer of simulated land use corresponding to `x1`. Only required if `x` is also a RasterLayer
`...`	additional arguments to `raster::aggregate`
`factors`	numeric vector of aggregation factors (equivalent to the 'fact' argument to `raster::aggregate` representing the resolutions at which model performance should be tested
`categories`	numeric vector of land use categories in observed maps. Only required if `x` is a RasterLayer
`labels`	character vector (optional) with labels corresponding to `categories`. Only required if `x` is a RasterLayer
