[R] recursive do.call

[Felix Andrews]

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 given in the argument list without a name?

My point is that you had better have a good reason to want to do it this way...

Cheers
Felix
