hello Team R, i have been using R for statistical analysis of phylogeny and i have installed the required packages phangorn and phytools but whenever i give the command "pml.fit" the program stops and it appears thatb r for windows GUI has stopped etc.. previously i thought it was a fault in my computer but it appears to happen the same when i give the command in any other computer. can i get a solution for this i have tried it on windows 10 and older versions can it be fixed? and also can you please send me the the commands for performing SH test of phylogeny using phangorn if possible. please do reply thank you [[alternative HTML version deleted]]
