search for: arma0fa

Hi, In my ongoing quest to track down the source of an error (see message "[R] optim error in arima" above), I find in the cource code for arima0 the following: arma0f <- function(p) { par <- as.double(fixed) par[mask] <- p .Call("arma0fa", G, par, PACKAGE = "stats") } I would like to know what the function "arma0f" does. Does the above mean that there is a function called "arma0fa" somewhere in R? Where is it? I couldn't find anything in Rinternals.h. Thanks, Nate
