There's another example of compiled code in http://www.jstatsoft.org/v33/i09/paper , but it probably won't say anything the 'Writing Code' guide doesn't already cover. I found the guide pretty complete ... I would suggest that you pack your parameters into a single numeric vector (or several, if that makes more sense) and pass them that way. What kind of infectious disease data do you have that will allow you to fit a model with thousands of parameters ... ?? (Just curious.) ______________________________________________ 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.
