[Rd] on the optim function

[Christophe Dutang]

Dear useRs,

I have just discovered that the R optim function does not return the number of iterations. 

I still wonder why line 632-634 of optim C, the iter variable is not returned (for the BFGS method for example) ? 

Is there any trick to compute the iteration number with function call number?

Kind regards

Christophe
