r - color.plot.phylo in PICANTE, how do you change size (cex) of tips or pass commands to plot.phylo? -

i found color.plot.phylo in package picante colors tips of tree based on trait. it's great function, haven't been able pass other commands phylo.plot function, as suggested.

i'm interested in changing size (cex) of tips , node.label. also, there way move legend?

this function wasn't written in way makes easy modify graphical parameters, because parameters such location of legend , size of text both hard-coded in function. if proficient @ r modify code of function change of values. example, modify following line in function:

plot.phylo(phylo, cex = 0.8, tip.color = tip.color, main = main, ...) 

to eliminate cex value , should able specify different cex values argument function. can find on writing/modifying functions in r elsewhere on site , in r documentation.
