| intpalette {shape} | R Documentation |
Returns color(s) that are a linear interpolation of a given set of colors
intpalette(inputcol, numcol=length(x.to), x.from=NULL, x.to=NULL)
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* |
Return value is a vector of *colors* in hexadecimal format.
This is different from colorRamp(R function), that returns a *function*
a vector of character strings giving the interpolated colors in hexadecimal format
