Details
详情----------Details----------
The function anovapin performs a one-factorial ANOVA for objects of class “marrayRaw” or “marrayNorm”. The predictor variable is the corresponding plate index as stored in the maPlate slot of obj; the response variable is the logged fold-change M=(log2(Ch2)-log2(Ch1)). The null hypothesis is equal mean(M) of groups of spots derived from the same microtiter plate i.e. a spot's M does not dependent on the plate of origin. The model formula used is M ~ (plate.index - 1) (without an intercept term).
功能anovapin执行一个对象类的“marrayRaw”或“marrayNorm”单因子变异数分析。预测变量是对应的板块指数maPlate插槽存储obj;响应变量是记录折变M=(log2(Ch2)-log2(Ch1))。零假设是平等mean(M)来自同一微孔板的点,即一个点的M组不依赖于起源板。使用该模型公式是M ~ (plate.index - 1)(无截距项)。
值----------Value----------
The return value is a list of summary statistics of the fitted model as produced by summary.lm. For example, the squared multiple correlation coefficient R-square equals the proportion of the variation of M that can be explained by the variation of plate index (based on the chosen
返回值是一个由summary.lm生产的拟合模型的汇总统计列表。例如,平方复相关系数R-square等于变异的比例M可以通过板块指数的变化(根据所选择的解释
