我想为我的数据计算回归，但是我遇到关于数据帧的错误？

Question

Regression <- top50 %>%
                lm(Length.~Popularity) %>%
                summary(Regression)

我得到的错误：

as.data.frame.default（data）中的错误：无法将类““ formula””强制转换为data.frame

Answer 1

如果要使用管道，请尝试：

library(magrittr)
top50 %>% lm(Length.~Popularity, data = .) %>% summary

类似于

summary(lm(Length.~Popularity, data = top50))

与mtcars一起使用可复制的示例

mtcars %>% lm(mpg~cyl, data = .) %>% summary

#Call:
#lm(formula = mpg ~ cyl, data = .)

#Residuals:
#   Min     1Q Median     3Q    Max 
#-4.981 -2.119  0.222  1.072  7.519
