www.nceas.ucsb.eduR translates various color models to hex, e.g.: •RGB (red, green, blue): The default intensity scale in R ranges from 0-1; but another commonly used scale is 0-255. This is obtained in R using maxColorValue=255. alpha is an optional argument for transparency, with the same intensity scale. rgb(r, g, b, maxColorValue=255, alpha=255)
