Get perceptual-derivative of continuous-palette

Get perceptual-derivative of continuous-palette

pev_data_derivative(.fcont, n_panel = 40, method = "cie2000",
  include_cvd = TRUE)

Arguments

.fcont	object that can be coerced to pev_fcont, when called with a numeric vector with values between 0 and 1, returns the corresponding (hex-code) values.
n_panel	numeric, number of panels into which to discretize the palette-function.
method	character, describes how the domain of the continuous palette is to be discretized, can be "post" or "panel" (using a fencing analogy).
include_cvd	logical or character, indicates to include data for for color-vision deficiency. Possible character values: "none", "protan", "deutan", "tritan".

Value

data.frame with variables cvd, x, hex, d_distance_d_x
