intpalette: color palettes

Description

Returns color(s) that are a linear interpolation of a given set of colors

Usage

intpalette(inputcol, numcol=length(x.to), x.from=NULL, x.to=NULL)

Arguments

inputcol

initial colors, *from* where to interpolate

numcol

number of colors to interpolate *to*

x.from

x-values *from* where to interpolate

x.to

x-values where to interpolate *to*

Value

• a vector of character strings giving the interpolated colors in hexadecimal format

Details

Return value is a vector of *colors* in hexadecimal format. This is different from colorRamp(R function), that returns a *function*

See Also

greycol, femmecol, shadepalette, colorRamp for comparable R function

Examples

intpalette(c("white","black"),n=10)
  grey(seq(1,0,length.out=10))
  image(matrix(nrow=1,ncol=100,data=1:100),
        col=intpalette(c("red","blue"),numcol=100),main="intpalette")
  image(matrix(nrow=1,ncol=100,data=1:100),
        col=intpalette(c("red","blue","yellow"),numcol=100),main="intpalette")
