[R] Color spalettes for black/white printing
Hi everybody! Does anyone know a good way to color my images so that when I print them out on a non-color-printer the colors used can be distinguished well? As I have many categories I would not want to assign the colors c(black, grey, white) by hand. Thank you!

That is bpy.colors() in the contributed sp package on CRAN, not in R itself. On Tuesday, March 5, 2013, ONKELINX, Thierry wrote: Have a look at bpy.colors() Best regards, ir.

As I have many categories I would not want to assign the colors c(black, grey, white) by hand. The colorspace package provides a wide range of colors that - when printed on a grayscale printer - still preserve an increasing/decreasing gray palette. To explore these, see choose_palette() in colorspace which opens a GUI, let's you play around with the palettes, see them in example displays, and also let's you collapse them to gray colorse (option: desaturate). Furtheremore, you can explore the effects of different types of color blindness (provided that the dichromat package is installed). Best, Z Thank you!
