Sorry.


Again,


I am currently using the mvpart package and would like to change the color scheme it uses, and was hoping someone could help me out. All of the papers I have found have used a grayscale but I can't seem to figure out how they did that! Currently, mvpart plots barplots in a repeating sequence of 3 shades of blue. So if you have 6 response variables the same shade of blue is used to represent two different response variables. I would like to use grayscale and a different shade of gray for each response variable (I have 7). However, the color is more important so if I can only use 3 shades of gray thats fine.

As for reproducible code:

using libraries ade4, vegan, gclus, cluster, RColorBrewer, labdsv, mvpart, MVPARTwrap

spe.mvpart <- mvpart(data.matrix(spe) ~ ., env, cp=0, xv"1se", xval=10, xvmult=100, uniform=TRUE)

I didn't include my data but if you need it, I will email you a subset.
