Discrete4.color

Discrete with four levels color dataset.

Description

Discrete with four levels color dataset. These colors look like four distinct colors when run through the vischeck simulator to see how they look for the three most common color vision deficiencies: Deuteranope, Protanope, Tritanope.

Usage

data("Discrete4")

Format

The format is: chr [1:4] "#E31A1C" "#1F78B4" "#FB9A99" "#A6CEE3"

Details

4x1 color scheme

Examples

data(Discrete4)
## Not run: 
library(RColorBrewer)
library(lattice)

## save(Discrete4, file="Discrete4.rda") ## data(Discrete4, package="HH")
##
barchart(~ 1:4, col=Discrete4, lwd=0, origin=0, horizontal=FALSE,
         xlab="Colors", scales=list(x=list(labels=Discrete4), y=list(labels=NULL)),
         main=paste("These colors look like four distinct colors when run through",
