Hi Gustavo, This used to be possible, and you could possibly use an older version of diversitree to do what you want to do. Things changed about a year, I think. Unfortunately, integrating time-varying functions efficiently is quite hard when parameters vary as arbitrary R functions. I've

Hi Richard, Thank you very much for the information! I will do my best to do it by myself, and will let you know if it worked or if I will need some more help. Thanks once again for the help! Cheers, On May 30, 2014 5:19 AM, Rich FitzJohn rich.fitzj...@gmail.com wrote: Hi Gustavo, This used

[R-sig-phylo] Exponential function on make.bd.t

2014-05-29 Thread Gustavo Burin Ferreira
Dear list, I am trying to create a likelihood function based on trees that were simulated with an exponential decay on speciation rates through time, and with constant extinction rates. I thought I could use make.bd.t from diversitree for this matter. However, it seems that this function doesn't
