Two possibilities:
<ul>
<li>
Have you pre-defined "f" before using nlm() ? Try something like
this:</li>
</ul>
> f
<- function(x) sum((x-1:length(x))^2)
<br>
> nlm(f, c(-1, 0, 0), hessian = TRUE, print = 0)
<br>
these two lines should generate (I only quote the first two lines of my
outputs):
<br>
$minimum

<br>
.

<ul>
<li>
If still now working, try to get R 1.0.1.</li>
</ul>
