[R] maPalette() and the number of colors returned (bug?)

[Ali Tofigh]

Hi,

The maPalette() function (in the marray package) does not always
return the number of colors requested. More specifically, if a middle
color is given and the number of colors requested is odd, then
maPalette returns either one more or one less than the requested
number of colors:

maPalette(low="white", high="red", mid="yellow", k=11)  # returns 12
colors <<<<<<
maPalette(low="white", high="red", k=11)  # returns 11 colors
maPalette(low="white", high="red", mid="yellow", k=13)  # returns 12
colors <<<<<<
maPalette(low="white", high="red", k=13)  # returns 13 colors

Is this a feature or a bug? I'm using R version 2.10.1.

Cheers
/Ali
