[R] abstol in nnet

[Haleh Yasrebi]

Hello All,
I would like to know what fit criterion (abstol arg)
is in nnet. Is it the threshold for the difference btw
the max output and target values?

Is the value at each iteration also the difference btw
max of output and target values over all output units
(case of multiple classes)?

How could value displayed at each iteration be related
to SSE and abstol be related to threshold SSE,
respectively?

Look forward to your reply
