示例#1

文件： test_factor.py 项目： tlperkins/pandas

    def test_value_counts(self):
        from pandas.tools.tile import cut

        arr = np.random.randn(4)
        factor = cut(arr, 4)

        self.assert_(isinstance(factor, Categorical))

        result = value_counts(factor)
        expected = value_counts(np.asarray(factor))
        tm.assert_series_equal(result, expected)
