jndplot: Perceptually-corrected chromaticity diagrams

Description

Plot options for jnd2xyz objects.

Usage

jndplot(x, arrow = c("relative", "absolute", "none"), achro = FALSE,
  arrow.labels = TRUE, arrow.col = "darkgrey", arrow.p = 1,
  labels.cex = 1, margin = "recommended", square = TRUE, ...)

Arguments

x

(required) the output from a jnd2xyz call.

arrow

If and how arrows indicating receptor vectors should be drawn. Options are 'relative' (default), 'absolute' or 'none'. See description.

achro

Logical. Should the achromatic variable be plotted as a dimension? (only available for dichromats and trichromats, defaults to FALSE).

arrow.labels

Logical. Should labels be plotted for receptor arrows? (defaults to TRUE)

arrow.col

color of the arrows and labels.

arrow.p

scaling factor for arrows.

labels.cex

scaling factor for arrow labels.

margin

accepts either 'recommended', where the function will choose margin attributes, or a numerical vector of the form c(bottom, left, top, right) which gives the number of lines of margin to be specified on the four sides of the plot. (Default varies depending on plot dimensionality).

square

Logical. Should a square plotting area be used? (defaults to TRUE)

...

additional parameters to be passed to plot, arrows and link{persp} (for 3D plots).

Value

Creates a plot, details of the plot depend on the input data.
