X <- as.data.frame(t(t_X))
colnames(X) <- c("c1", "c2", "c3", "A1", "A2", "A3", "A4", "A5", "A6")
X.labels <- X[,1:3]
X.training <- X[,4:9]
我正在尝试从A1-A6构建c1,c2,c3的线性模型。 不幸的是,我收到了错误:
Error in model.frame.default(formula = X.labels ~ X.training, drop.unused.levels = TRUE) :
invalid type (list) for variable 'X.labels'
当我做的时候
xlm <- lm(X.labels ~ X.training)
任何想法为什么?
答案 0 :(得分:1)
您只需要将一个依赖变量传递给lm。如果你想要每个c的模型你可以做:
xlm <- apply(X.labels,2,function(xl)lm(xl ~.,data= X.training))
xlm
获得:

lm(formula = xl ~ ., data = X.training)
