Hi all,
I hope someone can help me out here as I've been wracking my brain trying to figure out what the problem is. In short, I'm trying to fit a bunch of pathway models with the rayDISC function in corHMM, which I've done before with no issues. However, on this occasion the model just isn't running and returning the following error message:- Error in 1:nchar(as.character(string)) : NA/NaN argument This is not the most helpful message, particularly as no part of it seems to appear in the code for rayDISC so I assume it's an error from something that the function is calling itself. I have loaded the example data provided with the package and ran the same code I was using on the tree and an equivalent trait from the example data and this runs fine. I have tried comparing the structures of both the tree and data from the example to my own and I can't find a difference. There are a few NAs in my dataset but the function can handle this (a statement I verified by manually introducing NAs into the example data and it still runs). The tree has no polytomies or zero-length branches. I've attached my tree and a highly simplified version of the dataset and code I've been using (trimmed down to leave a simple example that reproduces the error message), I'd be very grateful if someone can figure out what's going on here.
