Plot the correlation matrix for the provided layercodes

#' plot_correlation creates a plot of the correlation between different layers

Usage

plot_correlation(layers_correlation, prettynames = list(),
  palette = c("#2c7bb6", "#abd9e9", "#ffffbf", "#fdae61", "#d7191c"))

Arguments

layers_correlation

matrix or dataframe. A square matrix with the layers correlations you want to plot as returned by layers_correlation or pearson_correlation_matrix.

prettynames

list. Optional list with as names the layercodes and as values the name of the layer to be used in the plot.

palette

character vector. optional vector with 5 entries for the range of colors to be used for the correlation matrix plot.

Value

A ggplot object that can be printed or saved.

Details

This function requires ggplot2 and plots the correlations for the layers in the same order as the layercodes are provided to this function.
