Re: [R] function is too long to keep source

[Spencer Graves]

	  I have a personal rule that any function I write that is longer than 
about one page should be modularized.  This rule pushes me to think 
carefully about how to structure the problem.  It also helps me debug my 
code and modify it as appropriate.  If I can develop appropriate 
"primatives", I get modules that I might be able to use in other 
applications.

	  This doesn't help with your immediate problem, but it might in the 
longer term.

Thanks a lot for your help.

But I am getting that error message when I am trying to
load my function. Then I can't use anything to minimise it.
Is there anything I can do to increase R's
capacity for loading very long functions?
Many thanks.

Have you considered "optim" in library(MASS)?  "optim" will optionally 
output the hessian, which can be used to obtain confidence intervals 
in many cases.

hope this helps.  spencer graves

Dear R users,

I am trying to minimise a function using "nlm".

I am getting the following error message: "Error: function is too 
long to keep source"

The function is really very long (about 100 A4 pages).

Is there anything I could do to solve this problem?

At the moment I am using "nlmin" in S-Plus with no problems but I'd 
prefer to use R.

Thank you very much in advance.

Regards.
Marcel
