Description Usage Arguments Value Author(s)

Determine color values according to a given range of values. From a given numeric vector z the range is determined and the values are linearly mapped onto the interval given by val.range. Then a color ramp using the colors given by color is created and the mapped values are transformed into hex color values.

1	mapCoordinatesToColor(z, colors=c("white", "black"), val.range=c(0.2, 0.8))

`z`	numeric vector.
`color`	vector of length two giving color values `c("white", "black")`.
`val.range`	numeric vector of lengths two (default `c(.2, .8)`).
