Hi, I can't find published papers using the make.simmap function in phytools (R) for discreet characters, however it is supposed to implement a similar method to SIMMAP 1.5 and it runs better then the original program. I've had problems imputing a matrix with uncertainties (?) in SIMMAP 1.5, and have to manually edit a huge matrix every time I run the program. Any reason to prefer the original program instead of Revell's function for R? Has anyone tested both with similar results? Thanks a lot.
