Part of Rudin 2.41 says that for a set E in ℝ

^{k}... "If E is not bounded, then E contains points**x**with |_{n}**x**|>_{n}*n*(*n*= 1, 2, 3,...)." I can understand the argument this far. I do not get the next sentence "The set S consisting of these points**x**is infinite and clearly has no limit point in ℝ_{n}^{k}". I can understand that S is infinite but to me S clearly does have limit points in ℝ^{k}. For example, take the real line, n = 1, S to be the set of points greater than 1 and ε>0. Every neighborhood of p = 2 with radius ε would contain a point in S making p a limit point. This contradicts what Rudin states as 'clearly'. What am I missing here?Thanks,
