Hi all,
is there a way to extract the name of a function, i.e. do the reverse
of match.fun applied to a character string? I would like to print out
the name of a function supplied to another function as an argument.
For example:
myFunc = function(x) { x+1 }
applyFunc = function(fnc, x)
{
fnc = match.fun(fnc)
fnc(x)
}
Is there a way to obtain "myFunc" from the argument fnc in applyFnc
the following call is issued?
applyFnc(myFunc, 1)
...or am I missing the basic fact that since arguments to functions in R are passed by copy, the name is lost/meaningless? Thanks, Peter
