But what is the difference between these functions and the ones that are documented in the help files?
Here's my version info FYI - its the standard install from the repo

<pre wrap="">Hi,
I am trying to fit some stock-recruitment relationships using the FLSR classes - this is the first time that I've played with them, and I have to say, I am very impressed with what you have setup here. However, it seems that there are a few missing that should be there according to the help file. ?SRModels gives me a nice list of the available models, but when I try the classic ar1 models, I get the following errors:
