  x,
  layers1,
  layers2,

  verbose = TRUE,
  area = TRUE
)

Arguments

`x`	A data.table containing the spatial-temporal-annual columns and two columns containing the data to be compared
`layers1`	A vector of character strings giving the layers from the second dataset to compare (should be columns in x and sum to 1 or 100)

`verbose`	A logical, if TRUE print out all the metric scores
