[R] names.data.frame?

[Leonard Mada]

Dear List members,


Is there a way to access the default names() function?


I tried the following:

# Multi-variable polynomial

p = data.frame(x=1:3, coeff=1)

class(p) = c("pm", class(p));


names.pm = function(p) {
# .Primitive("names")(p) # does NOT function
# .Internal("names")(p) # does NOT function
# nms = names.default(p) # does NOT exist
# nms = names.data.frame(p) # does NOT exist
# nms = names(p); # obvious infinite recursion;
nms = names(unclass(p));
}


Alternatively:

Would it be better to use dimnames.pm instead of names.pm?

I am not fully aware of the advantages and disadvantages of dimnames vs 
names.


Sincerely,


Leonard
