[R] package.skeleton only exports the first 73 lines of code
Hi all, apologies for the ignorance I'm about to describe: I'm trying to create a .r file for a function I've written (~300 lines of code). The function is called 'total' and I've entered the most simple package.skeleton: package.skeleton(name=test, list=c(total)) The export works fine (it creates sub folders for R, man, and DESCRIPTION, NAMESPACE and read-and-delete-me files, but total.r is only 73 lines long and the code stops in the middle of a phrase. Is there a character limit to the export, or am I failing to do something more complicated here?

Re: [R] package.skeleton only exports the first 73 lines of code
Copying the code as text into the incomplete .r file worked, good idea. I still don't know why the export didn't work though.

Re: [R] Non linear regression with complex equation
Apologies for the phrasing of the question.
I've sorted the problem (thanks Bert Gunter) by using the curly brackets {}
as below (using a simplified version of my real model). I hope this helps
someone else!

[R] Non linear regression with complex equation
Hi all, Is it possible to model a function where the unknown parameter appears both in the fitted equation AND in the determination of other parameters? E.g. y = a^2 + b/2 + k where a = 2/k and b = k^2 and the model needs to determine k? I know this is a very simple equation (its just an example), the one I am modelling is much more complicated! k appears in the equation which the n.l.r model fits, but it also affects other parameters in the equation. Please let me know if you know a way of achieving this. I realise it is possible to set up a loop where the modelled value for k is fed back in to a and b, and the model is run again - but it seems like there should be a more elegant way within one run of the model.
