Either setup so that cat() will be used to print it (add class + print
method) or return noquote(....) The latter will give this effect:
> noquote("function (x, y = NULL, type = \"p\", xlim = NULL, ylim = NULL, ")
[1] function (x, y = NULL, type = "p", xlim = NULL, ylim = NULL,
i.e. include line numbers.
