[R] optimization problem

[Jagat.K.Sheth at wellsfargo.com]

On the help page for nlm (type ?nlm) check out the 'See Also' section.
It mentions other functions such as 'optim' and 'nlminb' which can do
constrained optimizations.

  Dear list,
   hi !
   I am a R beginner and I have  a function to optimize .

   alpha = argmin{ f(x,alpha) }

   I want alpha to be in [0,1].  Is there any function that can work?

   I use nlm() but i can't fix the domain of alpha.

   thanks in advance
