Dear all,
 
Firstly, I do apologize if my question is simple and posted in the wrong place 
but I had no reply from the R-help mailing list (maybe it is too simple!).
 
 I was wondering why parscale is set to 20 in the "wild" function example used 
in ?optim. This function has only one parameter and if we set parscale equal to 
1 then the solution near the global minimum is not found.

I would use parscale only in cases the object function has more than one 
parameter to be optimised, shouldn't I? 
 
Many thanks in advance to all of you and kind regards,
Tom
