Vectors of colors for figures

Description

Creates different vectors of related colors that may be useful for figures.

Usage

jcolors(
  palette = c("default", "pal2", "pal3", "pal4", "pal5", "pal6", "pal7", "pal8", "pal9",
    "pal10", "pal11", "pal12", "rainbow")
)

Arguments

Value

Vector of character strings representing the chosen palette of colors.

Examples

par(mar=c(0.6,5.1,0.6,0.6))
plot(0, 0, type = "n", xlab = "", ylab = "", xlim = c(0, 6), ylim = c(4, 0), yaxs = "i",
     xaxt = "n", yaxt = "n", xaxs = "i")
axis(side=3, at=1:3, c("default", "pal2", "pal3"), las=1)

def <- jcolors("default")
points(seq(along = def), rep(1, length(def)), pch = 22, bg = def, cex = 8)
pal2 <- jcolors("pal2")
points(seq(along = pal2), rep(2, length(pal2)), pch = 22, bg = pal2, cex = 8)
pal3 <- jcolors("pal3")
points(seq(along = pal3), rep(3, length(pal3)), pch = 22, bg = pal3, cex = 8)

continuous palettes of colors for figures

Description

Creates different color palette functions

Usage

jcolors_contin(
  palette = c("default", "pal2", "pal3", "pal4", "pal10", "pal11", "pal12", "rainbow"),
  reverse = FALSE,
  interpolate = c("spline", "linear"),
  ...
)

Arguments

Value

returns a function that takes an integer argument (the required number of colors), which then returns a character vector of colors

Examples

colfunc <- jcolors_contin()
jcols   <- colfunc(1000)
n       <- length(jcols)
image(1:n, 1, as.matrix(1:n),
      col  = jcols,
      xlab = "", ylab = "",
      xaxt = "n", yaxt = "n", bty = "n")
