是什么之间的区别"+"在GGPLOT2运营商和"%>%" 在magrittr操作？
我被告知它们是相同的,但是如果我们考虑以下脚本.
library(magrittr)
library(ggplot2)
# 1. This works
ggplot(data = mtcars, aes(x=wt, y = mpg)) + geom_point()
# 2. This works
ggplot(data = mtcars) + aes(x=wt, y = mpg) + geom_point()
# 3. This works
ggplot(data = mtcars) + aes(x=wt, y = mpg) %>% geom_point()
# 4. But this doesn't
ggplot(data = mtcars) %>% aes(x=wt, y = mpg) %>% geom_point()
