Short update on the Palantir visualization

September 26, 2013 in Ivan's Blog

I have put together a simplistic R script that draws a few circles next to the branches on a tree.

Thus far, it is a rather simple hack that uses a the obscure numbering of branches provided by APE. I foresee that it might be necessary to come up with a better way to encode branch identity. This really depends on what the output from Palantir is.

Another problem is that I am using the plotrix library for drawing things. Sadly, it does not scale well when a window is resized, so you might end up with elliptical circles. Additionally, I will have to play with the coordinates of the circle offsets to make sure they consistently fit on the picture.

Hopefully, when I get the data, it will not be too hard to make work properly.

The current usage information is provided in the repository description.
