pruneL function

I guess this function is specially useful to our group in which we play with L table. But might be less useful than phylo2L function :-)

Following last post, this function pruneL prunes an L table by removing the extinct lineages.

pruneL function can be found here if you want to improve the function. There is a huge room for improvement. This version is only the first draft of the function. And I guess I should remove the argument dropextinct. It doesn’t make any sense. What do you think?
