huePositionPlot: Hue Position Chart

Description

A simple visualization of the hue positions for a given Munsell value/chroma according to Soil Survey Technical Note 2.

Usage

huePositionPlot(
  value = 6,
  chroma = 6,
  chip.cex = 4.5,
  label.cex = 0.75,
  contour.dE00 = FALSE,
  grid.res = 2
)

Arguments

value

a single Munsell value

chroma

a single Munsell chroma

chip.cex

scaling for color chip rectangle

label.cex

scaling for color chip

contour.dE00

logical, add dE00 contours from CIELAB coordinates (L,0,0), L is a constant value determined by value and chroma

grid.res

grid resolution for contours, units are CIELAB A/B coordinates. Caution, small values result in many pair-wise distances which could take a very long time.

Examples

# NOT RUN {
huePositionPlot(value = 6, chroma = 6, contour.dE00 = TRUE, grid.res = 2)

# }
