To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

Onderwerp: [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!

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
