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

Dear useRs,
I have just discovered that the R
Also Surv objects are matrices and they share the same problem when
rbind-ing data.frames.
If contained in a data.frame, Surv objects loose their class after
rbind and therefore do not more represent Surv objects afterwards.
Using rbind with Surv objects outside of data.frames shows a similar
