Description:
Color values in R are often represented as strings of hexadecimal colors or named colors.This package offers fast conversion of these color representations to either an array of red/green/blue/alpha values or to the packed integer format used in native raster objects.This fast conversion of colors is implemented using an order-preserving minimal perfect hash derived from Majewski et al (1996) 'A Family of Perfect Hashing Methods' <doi:10.1093/comjnl/39.6.547>.
