Create Customized Color Scales

Description

Creates color scales for numeric values using predefined color palettes. The function supports optional log-transformation of the input values, handles constant vectors gracefully, and maps each numeric value to a color in the selected palette.

Usage

f_colorz(
  z,
  tf = FALSE,
  palname = "viridis",
  col_num = 100,
  verbose = FALSE,
  ...
)

Arguments

z	Numeric vector. Values whose colors should be computed.
tf	Logical. If TRUE, applies a transformation to the color scale (default is FALSE).
palname	Character. Name of the palette. Available palettes: "black", "redblue", "ratios", "rainbow", "awi", "viridis", "inferno", "terrain.colors", "gray".
col_num	Integer. Number of colors in the palette (default: 100).
verbose	logical; if TRUE, show progress messages.
...	Additional arguments passed to methods.

Value

A character vector of colors of the same length as z.
