Usage

layers_correlation(layercodes = c())

Arguments

layercodes

character vector or dataframe. Codes of the layers, you want the correlation matrix of, as a character vector or a dataframe with a "layer_code" column. With the default empty vector the correlation between all layers is returned.

Value

A dataframe with the Pearson product-moment correlation coefficients.
