createColorPalette(name, n = 1, alpha = 1, start = 0, end = max(1,
  n - 1)/n, s = 1, v = 1, bias = 1, space = c("rgb", "Lab"),
  interpolate = c("linear", "spline"), clrs = c("#00007F", "blue",
  "#007FFF", "cyan", "#7FFF7F", "yellow", "#FF7F00", "red", "#7F0000"),
  showAsWheel = FALSE, showAsBar = FALSE)

Arguments

name

- name of base palette to use (pre-defined: 'rainbow','heat','topo', 'cm', and 'jet'; 'ramp' for new palette)

n

- number of colors to include in palette

alpha

- transparency (0-1)

start

- value associated with 1st color in palette

end

- value associated with last color in palette

s

- parameter passed to "rainbow" function

v

- parameter passed to "rainbow" function

bias

- ??

space

- colorspace ('rgb' or 'Lab')

interpolate

- interpolation scheme ('linear' or 'spline')

clrs

- vector of colors defining base palette

showAsWheel

- flag (T/F) to show the final palette as a colorwheel

showAsBar

- flag (T/F) to show final palette as a colorbar

Details

New (interpolated) palettes can be created based on the following pre-defined palettes:
'rainbow', 'heat', 'topo', 'cm', and 'jet'
Specifying a pre-defined palette eliminates the need to specify the 'clrs' color vector.
Palettes can created based on arbitrary base palettes by specifying name as 'ramp' and providing a vector of colors to use as the base palette (via clrs). This appraoch uses the grpahics function "colorRampPalette" to create the palette.

Value

a color palette
