Main function for retrieving colors from palettes with intelligent handling of discrete and continuous data.
Usage
get_palette(
x,
n = 100,
palette = "Paired",
palcolor = NULL,
type = "auto",
keep_names = TRUE,
alpha = 1,
matched = FALSE,
reverse = FALSE,
NA_keep = FALSE,
NA_color = "grey80",
transparent = TRUE
)Arguments
- x
Vector of values to map to colors (character, factor, or numeric)
- n
Number of colors for continuous palettes
- palette
Name of the palette to use
- palcolor
Custom colors (overrides palette)
- type
Type of palette: "auto", "discrete", or "continuous"
- keep_names
Whether to keep names on color vector
- alpha
Transparency level (0-1)
- matched
Return colors matched to x values
- reverse
Reverse the color order
- NA_keep
Include color for NA values
- NA_color
Color for NA values
- transparent
Use true transparency vs color blending
