It is complicated if the argument list is all mixed in together as in
your example. You would have to look up argument lists for possible S3
methods (e.g. 'digits' is an argument to print.default), and then
there is S4 to think about. Also, can arguments be matched by partial
names? Can they be
Hmmm I was hoping there would be a more natural way to do it. For example,
if you actually try to call the first function with all arguments:
lm(formula=dist~speed, digits=3, data=cars)
R will match whatever it can, and give you a warning with the names of
remaining unmatched arguments. The only

I'm not 100% sure of your problem...
It seems that you may want to consider these functions

Also, making a separate wrapper function for what you want to do. E.g.:
ModelPrinterFun = function(dat){
model = glm(dist~speed, data=dat)
print(coef(model), digits=3)
}
I see what you are saying. The application I am working with is making
convenient single-call (user) interfaces for R functions, and I don't
want to write a wrapper for every possible combination (like Gene
suggested below). If we don't consider the ... arguments for a second,
and only consider
I would like to define a recursive equivalent to call or do.call, which takes
a vector of multiple function names and 'chains' them, by greedy matching of
arguments down the chain. For example, I would like to be able to do:
rec.do.call(c(glm,coef,print), list(formula=dist~speed, digits=3,
6 matches
