[R] Two or more dimensional root (Zero) finding
Good morning to all, I should find the zero of a specific function with respect to a vector of arguments. Does it exist something similar in R? Thank you very much, Enrico Foscolo

A reasonable approach is to search for the minimum of the square of the function (using optim(), nlmin(), etc.).
