Hello Thomas, This code seems to be fine and its now working well.
I read the about the FME package, but I have one doubt, as in the data set given in the paper, it showing a nice kinetics of the viral growth, so my question is what if there is a sudden increase in viral growth after some interval, say Bimodal growth curve? How does it fits the bimodal growth curve? I tried with FME but I am not getting the desired results. May be you can explain me a little, I would be really grateful to you. :) Thanks a lot, Himanshu -- View this message in context: http://r.789695.n4.nabble.com/How-to-find-best-parameter-values-using-deSolve-n-optim-tp4506042p4632528.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
