我正在寻找一种方法来合并/突变这两个数据帧，并将X $ x_i_plus变量绑定到Y。
XY <- merge(X, Y, by.x = c("spd", "gender", "age"), by.y =c("spd", "gender", "age"))
我认为我可以按spd，性别和年龄进行合并，但这没有用。
我还考虑过使用dpylr突变一个新变量：
test <- test %>% group_by(qnhs, gender, age) %>% mutate(x_i_plus = X$x_i_plus) %>% ungroup()
这也不起作用。
> X
spd gender age x_i_plus
