Heh, yeah, it is a bit long-winded. Essentially you take the input
data and run it through those steps to produce the JPT at the end.

Part of it is the odometric ordering of the data.

I don't think so, at least not exactly, but if I can get my head
around what that code does it might actually be doing what I want.

Thanks for that, I will attempt to break the R code down into chunks
that I can understand and go from there.
