WebnormalizeBetweenArrays is the main normalization function for one-channel arrays, as well as an optional function for two-colour arrays. normalizeBetweenArrays uses utility functions normalizeMedianAbsValues, normalizeMedianAbsValues, normalizeQuantiles and normalizeCyclicLoess, none of which need to be called directly by users. Web数据如下，是一个表达矩阵和分组信息，我在b站的geo课程多次讲解了，大家读懂： 使用 limma 的 removeBatchEffect 函数 需要注意的是removeBatchEffect 函数这里表达矩阵和需要被去除的批次效应是必须参数，然后本来的分组也是需要添加进入，这样与真实分组相关的差异就会被保留下来。
