continuous palettes of colors for figures

Creates different color palette functions

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

Arguments

palette	Character string indicating a palette of colors.
reverse	logical value indicating whether the color palette should be reversed. Defaults to FALSE
interpolate	Character string for color interpolation method. "linear" or "spline" interpolation available
...	other arguments to be passed to colorRampPalette. See colorRampPalette for details

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")
