Description
Generate random colors.
Usage
randomColor(n, hue = "random", luminosity = "random")
Arguments
n |
number of colors to be generated |
hue |
the desired hue; it can be a number between 0 and 360, a hexadecimal color code, or a string taken among the possibilities "random", "red", "orange", "yellow", "green", "blue", "purple", "pink", or "monochrome" |
luminosity |
the desired luminosity, a string taken among the possible choices "random", "light", "bright", or "dark" |
Value
A character vector of hexadecimal color codes.
Examples
# pie chart ####
n <- 20
clrs <- randomColor(n, hue = "red", luminosity = "dark")
opar <- par(mar = c(0, 0, 0, 0))
pie(rep(1, n), col = clrs)
par(opar)
# Fermat spiral ####
n <- 400
theta <- seq(0, n/3, length.out = n)
x <- sqrt(theta) * cos(theta)
y <- sqrt(theta) * sin(theta)
pts <- cbind(x, y)
clrs <- randomColor(n, hue = "random", luminosity = "bright")
opar <- par(mar = c(0, 0, 0, 0), bg = "black")
plot(
pts, asp = 1, xlab = NA, ylab = NA,
axes = FALSE, pch = 19, col = clrs
)
par(opar)
