Example data sets for accuracy assessment

aa_examples.Rd

Example data from published accuracy assessments papers (see references).

Usage

aa_examples(source_name = NULL)

Arguments

source_name

character string pointing to one of the following sources: "card", "congalton", "stehman", "stehman2014", "olofsson"

Value

A list containing or or more of the following elements. The actual elements depend on the source.

  • citation: citation for the source

  • reference: a vector of reference labels

  • map: a vector of reference labels

  • stratum: a vector of stratum labels

  • h: a vector of stratum labels associated with the stratum sizes N_h

  • N_h: stratum sizes (areas) associated with the stratum labels h

  • w: stratum weights (area proportions)

  • m: confusion matrix
