col.scale

Description

Assigns rgb colors to numeric data values in vector "x".. maps scalar values in val.range (default c(0,1)) to a linear color scale of between col.min (default white) and col.max (default black), each which are length 3 vectors or characters. RGB values are scaled between 0 and 1.

Values below and above val.min and val.max are mapped to col.max and col.max respectively

Assign rgb colors to numeric data

Assigns rgb colors to numeric data values in vector "x".. maps scalar values in val.range (default c(0,1)) to a linear color scale of between col.min (default white) and col.max (default black), each which are length 3 vectors or characters. RGB values are scaled between 0 and 1. Values below and above val.min and val.max are mapped to col.max and col.max respectively

Usage

col.scale(
  x,
  val.range = c(0, 1),
  col.min = "white",
  col.max = "black",
  na.col = "white",
  invert = F
)

col.scale(
  x,
  val.range = c(0, 1),
  col.min = "white",
  col.max = "black",
  na.col = "white",
  invert = F
)

col.scale(
  x,
  val.range = c(0, 1),
  col.min = "white",
  col.max = "black",
  na.col = "white",
  invert = F
)

Arguments

x	length n numeric or integer data to color
val.range	data range to assign to colors (= c(0,1))
col.min	character color to interpolate minimum value in val.range (='white')
col.max	character color interpolate maximum value in val.range (='black')
na.col	color to give to na.values (='white')
invert	logical flag whether to flip min and max (=FALSE)

Value

length n vector of colors

length n vector of colors
