Regarding cocorresp; I know the R code is reproducible and comparable with Andre Schaffers Matlab code because I ported the latter to R. I didn’t have easy access to Matlab so I used Octave to evaluate the Matlab scripts for most of the code and compare them with R and the outputs in the paper in Ecology. The results are repeatable to many decimal places between the two software packages. Now, there may be bugs or errors in the math, but if so those bugs are in both packages & reproducibly so!

(You are free to quote me on this in your rebuttal, of course! And FYI CoCA is now in Canoco so one other option, also not free but not bankruptcy-level costs, for reproducing your results.)
