[R] function is too long to keep source

[Marcel Vieira]

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
