colorMixtureVenn: Create a Venn Diagram of Simulated Color Mixtures

In ncss-tech/sharpshootR: A Soil Survey Toolkit

Create a Venn Diagram of Simulated Color Mixtures

Description

Create a Venn Diagram of Simulated Color Mixtures

Usage

colorMixtureVenn(
  chips,
  w = rep(1, times = length(chips))/length(chips),
  mixingMethod = "exact",
  ellipse = FALSE,
  labels = TRUE,
  names = FALSE,
  sncs = 0.85
)

Arguments

chips	character vector of standard Munsell color notation (e.g. "10YR 3/4")
w	vector of proportions, can sum to any number, must be same length as chips
mixingMethod	approach used to simulate a mixture: see aqp::mixMunsell() for details
ellipse	logical, use alternative ellipse-style (4 or 5 colors only)
labels	logical, print mixture labels
names	logical, print names outside of the "sets"
sncs	scaling factor for set names

Value

This function is called to create graphical output, nothing returned.

Examples

if(requireNamespace("venn") & requireNamespace("gower")) {

chips <- c('10YR 8/1', '2.5YR 3/6', '10YR 2/2')
names(chips) <- c("tan", "dark red", "dark brown")

colorMixtureVenn(chips)
colorMixtureVenn(chips, names = TRUE)

colorMixtureVenn(chips, w = c(1, 1, 1), names = TRUE)
colorMixtureVenn(chips, w = c(10, 5, 1), names = TRUE)

}
