Colours for the parameter values present in one method's rows — method_parameter_color

The plot code carries two spellings of each parameter label: the plotmath expression the legend is drawn with, and the plain text it was built from. Only the plain text still holds the numbers that place a value on its method's ramp, while the scale has to be keyed by the expression the layers map to, so the two are paired up row by row here.

Usage

method_parameter_color_map(df_subset, method, ...)

Arguments

df_subset: One method's rows, carrying parameters_labels and parameters_labels_not_latex.
method: The method key or display label.
...: Passed on to method_parameter_colors().

Value

A character vector of hex colours, named by the plotmath labels.
