Re: [R] color2D.matplot axis names

Looking into the color2D.matplot code showsthat this is by design. You might want to contact the package maintainer and send suggestions how to patch the function (or better, send the patch itself) in order to show appropriate labels.

Of course, for a worksround, disable axes


     show.values=TRUE, axes=FALSE)

and add manually constructed axes by the axis() function later on.
