[R] Variable number of arguments to function

Dear R List,

I have used ... to pass a varying number of arguments to a function. The function takes parts of specialized data objects (they happen to be lists) and makes comparative graphs and analyses. The code shell looks like this:

models.compare <- function(...) {

## Get the data objects passed

   models <- list(...)
   nmodels <- length(models)
## Get names of models:

   modelnames <- as.character(substitute(c(...))[-1])    ##### much code omitted here #####
}

Now I would like to pass a few named arguments to the function as well, to control how it prints, plots, makes files. I am seeking advice on the simplest way to do this (along with the varying number of data arguments).

Mike
