colourScheme: colourScheme

In R-graphic-design/RGD: A package for Graphic Design in R

colourScheme

Description

Creates a single function that can create colour schemes using many different packages with the option of interpolation.

Usage

colourScheme(
  numberOfColours = 10,
  scheme = "BW",
  colours = NULL,
  bias = 1,
  space = c("rgb", "Lab"),
  alpha = FALSE,
  interpolate = c("linear", "spline"),
  reverse = FALSE,
  discrete = TRUE,
  randomise = FALSE
)

Arguments

numberOfColours	The number of colours returned. Defaults to 10.
scheme	The palette or function to use. Used when colours is NULL. Defaults to "BW" for black and white. See details for more information.
colours	A starting set of colours that will be interpolated.
bias	used by colorRampPalette
space	used by colorRampPalette
alpha	used by colorRampPalette
interpolate	used by colorRampPalette
reverse	Reverses the final colour order. Defaults to FALSE
discrete	Defaults to TRUE
randomise	logical. If TRUE randomises the order of the answer. Defaults to FALSE

Details

The possible values of scheme are;

• "BW" and "BWrev" for greyscale

• "rainbow" and "rainbowrev" which uses rainbow()

• "heat" and "heatrev" which uses heat.colors()

• "terrain" and "terrainrev" which uses terrain.colors()

• "topo" and "toporev" which uses topo.colors()

• "cm" and "cmrev" which uses cm.colors()

• "BrBG","PiYG","PRGn","PuOr","RdBu","RdGy","RdYlBu", "RdYlGn","Spectral","Accent","Dark2","Paired","Pastel1","Pastel2","Set1", "Set2","Set3","Blues","BuGn","BuPu","GnBu","Greens","Greys","Oranges", "OrRd","PuBu","PuBuGn","PuRd","Purples","RdPu","Reds","YlGn","YlGnBu", "YlOrBr" and "YlOrRd" from the RColorBrewer package

• "plasma", "plasmarev", "viridis", "viridisrev", "magma", "magmarev", "inferno" and "infernorev" from the viridis package.

Value

Returns a vector of colours of the given length.
