In AGAuffret/HistMapR: Rapid digitization of historical land-use maps in R

Plot a colour table for visual inspection during classification testing.

Description

This function takes the colour summary table output from click_sample and produce the colour plot. This allows the user to create the colour plot and experiment with different values of "errors" without needing to classify the map. It does not change the colour table input, but is simply a tool to visually determine which error value should be input into the "raster_reclass" function.

Usage

plot_colour_table(colour.table, errors = 0)

Arguments

colour.table	Data frame. Output from click_sample (or matching dataframe).
errors	Integer. Adjust maximum and minimum colour bands by the standard error times this term.

Value

Plots a colour table
