Here, we identify an additional activity of R-2-HG: tumor cell–derived R-2-HG is taken up by T cells where it induces a perturbation of nuclear factor of activated T cells transcriptional activity and polyamine

This example demonstrates how to replicate the “Error in .subset(x, j) : invalid subscript type ‘list'”. Let#s assume that we want tocreate a subset of our data frame. Then, we might try to select the columns x1 and x3 as shown below: ...
cor_gather(): takes a correlation matrix and collapses (or melt) it into long format data frame (paired list) cor_spread(): spread a long correlation data frame into wide format (correlation matrix). 取子集: cor_select(): subset a correlation matrix by selecting variables of interest. pull...

平均模型系数:包含“full"和”subset”两种形式,‘subset’ (‘conditional’) 平均表示只平均该变量回归系数存在的模型。 模型比较最好在同类模型中进行,如,不要使用模型评价参数直接比较lm模型与lmm模型。当模型自变量较多需要进行筛选或想进行模型平均时,推荐使用MuMIn包进行最优子集筛选和模型平均。更详细教程可查看...
