This function maps numeric values within a specified range to a color gradient defined by two colors. It returns the corresponding hex codes and optionally plots the color scale.
Usage
get_hex_colors(
numeric_values,
lower_bound = 0,
upper_bound = 1,
color_low = "orange",
color_high = "green",
resolution = 100,
plot_scale = FALSE
)Arguments
- numeric_values
A numeric vector of values to map to the color scale.
- lower_bound
A numeric value specifying the lower bound of the numeric values (default: 0).
- upper_bound
A numeric value specifying the upper bound of the numeric values (default: 1).
- color_low
A string specifying the color at the low end of the gradient (default: "orange").
- color_high
A string specifying the color at the high end of the gradient (default: "green").
- resolution
The number of colors to generate in the color gradient (default: 100).
- plot_scale
A logical value indicating whether to plot the color scale (default: FALSE).
Examples
# Example usage of get_hex_colors
numeric_values <- c(5, 10, 15)
get_hex_colors(numeric_values, lower_bound = 0, upper_bound = 20, color_low = "blue", color_high = "red")
#> [1] "#4000BE" "#80007E" "#BE0040"
