My goodness! This is **NT** a reproducible example. You need to give us the
exact data you fitted to reproduce your results/diagnose your problem.

Subject: Re: [R] number of iteration s exceeded maximum of 50
Sorry, I thought it was a straightforward question inside
which I was stuck .
I used nls( ) to estimate a and b in this function.
nls(y~ a*x^b,start=list(a=a1,b=b1)
seems the start list I gave was not able to reach convergence
and it gave notes: number of iteration s exceeded maximum of
50. Then I put nls.control(maxiter = 50, tol = 1e-05,
minFactor = 1/1024) in nls( ), and modified the argument of
maxiter = 500. But it worked out as the same way and noted :
number of iteration s exceeded maximum of 50. I have totally
no idea how to set this parameter MAXITER.
Thanks for any information!

Hi all,
I found r-site-research not work for me these days.
When I was doing nls( ) , there was an error
"number of iterations exceeded maximum of 50". I set
number in nls.control which is supposed to control
the number of iterations but it didn't work well.
Could anybody with this experience tell me how to
fix it? Thanks in advance!
We cannot make suggestions unless you tell us what
you tried yourself.
Id possible, please gib4ve a reproducible examle.
