clr_extract: Extract multiple components

In EmilHvitfeldt/prismatic: Color Manipulation Tools

Extract multiple components

Description

Extract multiple color components at the same time.

Usage

clr_extract(
  col,
  components = c("red", "green", "blue", "hue_hsl", "saturation", "lightness", "hue_hcl",
    "chroma", "luminance")
)

Arguments

col	A colors object (see color()) or a vector of any of the three kinds of R color specifications, i.e., either a color name (as listed by grDevices::colors()), a hexadecimal string (see col2rgb()), or a positive integer i meaning grDevices::palette()⁠[i]⁠.
components	A character vector of components that should be extracted. See Details for allowed components.

Details

The allowed values for components are:

• red

• green

• blue

• hue_hsl

• saturation

• lightness

• hue_hcl

• chroma

• luminance

clr_extract() is to be preferred over other extraction functions if you need to extract multiple components at the same time, since it doesn't repeat transformations.

Value

A data.frame of components.
