Hi
You may like to try this
T <- rtree(10) #random tree with 10 terminals
plot(T)
nodelabels(pie=((1:8)*10/100))
#Just replace (1:8)*10 with the actual values
I hope this helps

Another possibility (maybe more flexible) is to get the coordinates of
the nodes and then call rect(). Something like:
tr <- rcoal(10)
plot(tr, "p", FALSE)
lastPP <- get("last_plot.phylo", envir = .PlotPhyloEnv)
x <- lastPP$xx[-(1:lastPP$Ntip)]
y <- lastPP$yy[-(1:lastPP$Ntip)]
s <- 0.3
par(xpd
Ah, not really. I am thinking more of an actual matrix, where matrix entries
represent support values, and are colored proportionally. Ie - something like:
image(t(matrix(data=c(95, 60,75,85), nrow=2, ncol=2)), col=heat.colors(4),
yaxt='n', xaxt='n')

Hi Jacob,
It is possible to call nodelabels() several times to do something
similar to what you want by playing with the adj argument which is
c(0.5, 0.5) by default (ie, the label is centered on the node). You can
try this:
tr <- rcoal(5)
plot(tr, "p", FALSE)
for (h in c(0.4, 0.5, 0.6))
Dear R-sig-phylo,
Does there exist a function to plot heatmaps at internal nodes of a tree? For
example, to illustrate support values from different phylogenetic analyses — ie
given a set of 3x3 matricies of support values for particular nodes.
It seems like there may be a partial (and
