Comparison between two datasets of categorical variables

Description

Calculates a Statistics object (which contains the Cohen's Kappa scores) given data.table of with two layers of categorical data (eg. biomes, land cover classes).

Usage

categoricalComparison(
  x,
  layers1,
  layers2,
  additional,
  verbose = TRUE,
  area = TRUE
)

Arguments

`x`	A data.table containing the spatial-temporal-annual columns and two columns containg the data to be compared
`layers1`	A character string giving the first layer to compare (should be a column in x)
`layers2`	A character string giving the second layer to compare (should be a column in x)
`additional`	A list of functions define additions metrics, see the custom.metrics argument of `compareLayers`
`verbose`	A logical, if TRUE print out all the Kappa scores
`area`	A logical, if true weight the metrics by gridcell area (not currently implemented) Note that there are many other slots in a Statistics object which will not be filled in the resulting object because they are for continuous as opposed to categorical data
