It would help us debug if you could report the command that you tried to execute that led to the error (and the context or directory from which it's being run).
Hello, I was just trying to execute the code of the example line by line. It fails when executing this line: fit <- sampling(model, data = lynx_hare_data, seed = 123) Thank you for the article by the way. I am interested in LV models and will come back to you with some questions if you don't mind.
The best place to ask questions is Discourse. If there's a particular question you have for me, please ping me via email as I don't see all the modeling questions going by. Fair warning---that was just a simple example I put up as it's kind of a "hello world" for ODE models in a lot of applied math settings. I'm neither an expert in ODE models nor population dynamics.
I'm guessing your problem here is that data
is not defined yet when that call is made. I'm going to close this issue. If you have a reproducible bug (in the form of a sequence of commands that if we run them, tickles the bug), this is the place to post it.
