\n is for TERMINATING lines. Just like in C, C++, Java, C#, Python, Ruby, Erlang, pretty much everything that uses \n in strings at all.
sprintf("gradtol = %e\n", mycontrol$gradtol) makes sense. More generally, sprintf() takes as many arguments as you care to give it, so cat(sprintf("tol = %e\nreltol = %e\nsteptol = %e\ngradtol = %e\n", mycontrol$tol, mycontrol$reltol, mycontrol$steptol, mycontrol$gradtol)) R being R, I'd prefer using ?format myself.
