Thanks so much for your reply. I am using try but nlme never returns!! and I think the process is getting killed by the system as it is taking over all the memory. However, I do like William Dunlap's idea of using R.utils::withTimeout to limit the time.
Thanks again for your help! ________________________________________ From: Bert Gunter [gunter.ber...@gene.com] Sent: Tuesday, December 02, 2014 4:30 PM To: Ramiro Barrantes Cc: r-help@r-project.org Subject: Re: [R] How to have NLME return when convergence not reached ?try Or ?tryCatch Bert Sent from my iPhone -- please excuse typos. > On Dec 2, 2014, at 12:57 PM, Ramiro Barrantes <ram...@precisionbioassay.com> > wrote: > > Hello, > > I am trying to fit many hundreds of simulated datasets using NLME (it's all > in a big loop in R).
