...function. So I also can't do something like initialize = function(aminoAcids=bibliospec::AminoAcids){ I guess this is an R FEATURE.

Hi, Would like to make an image however the values in z are not on an uniform grid. Have a dataset with length(x) == length(y) == length(z) x[1],y[1] gives the position of z[1] and would like to encode value of z by a color. looking for something like plot(x,y, col = z) where col for z is cleverly chosen from a colorscale. Hope I made clear what I am looking for. Thanks Eryk

[-3,-2.9) etc. I would assume R has such a function but I cant recall which one
