Dear Kamila.

In what way would you like to adjust the tip labels? The most useful adjustment that I have found is the argument lab4ut="axial" which plots the labels with the angle of the corresponding terminal edge. It is also possible to offset the tip labels using label.offset>0.

We can also get the positions of the tips in the coordinates of our plotting device as follows:

obj<-get("last_plot.phylo",envir=.PlotPhyloEnv)
x<-obj$xx[1:obj$Ntip]
y<-obj$yy[1:obj$Ntip]

You can then use these coordinates to plot your labels any way you choose!

Many thanks,
