If it is, you know your loop terminated because you hit itermax, and not because your algo converged: ... ... iter <- 0 while (((Fpt - Fpi) > tolerance) && (iter < itermax)) { Fpi = Fpt Fpt = K*Time + M*S*log(1+ Fpi/(M*S)) Fp0 = Fpt iter <- iter + 1 } if (Fpt - Fpi > tolerance) { warning("Algorithm reached itermax and did not converge") } ... -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
