Research direction

Start by reading the treeplot implementation and how it constructs the dendrogram, labels, and ggplot layers. Reproduce the supplied treeplot(gsetree, hclust_method = "complete") call, then determine whether these aesthetics are exposed or require an API change. Done means a documented way to customize the requested colours and appearance.

Description

Hi!
Really nice package, thank you! I am trying to modify the colouring for treeplot. I was able to modify the code for gseaplot2 pretty easily by changing the function code, but doing this for treeplot returned:

function (x, ...) 
standardGeneric("treeplot")
... etc

I then tried simply tagging on ggcode to the plotting call, which worked to change the cluster block colours (via fill), and the dot point colours using colour, but this still leaves the dendogram and labels the previous and unwanted colours;

gsetreeplot <- treeplot(gsetree, hclust_method = "complete") + 
    scale_fill_manual(values = c("#006600",
                                 "#300000",
                                 "#ff9900",
                                 "red",
                                 "#1d3e59")) +
     scale_colour_gradient(low = "#000000",
                           high = "#ffffff",
                           guide = "p Value")

How can I change these aesthetics? And moreover, how would I go about further modifying the appearance of this plot (line widths, dot borders, etc), like I was able to do by modifying the gseaplot2 function code?

Thanks again,
Dan
