R a 不等于r a b
Web5.3 逻辑运算函数. 因为R中比较与逻辑运算都支持向量之间、向量与标量之间的运算, 所以在需要一个标量结果时要特别注意, 后面讲到的if结构、while结构都需要逻辑标量而且不能是缺失值。这时,应该对缺失值结果单独考虑。 WebWe and our partners store and/or access information on a device, such as cookies and process personal data, such as unique identifiers and standard information sent by a …
