尝试应用过滤器并选择时我是否正确?

我试图观察这些年来由于凯恩斯在人均 GDP 中发生的变化。这是我写的代码: 我得到的错误:

ggplot(., aes(y = year, x = new_gdp, color = as.factor(Keynes))) 中的错误:找不到函数“ggplot”

这是我在插入 rlang::last_trace() 时看到的

也许你想要这样的东西:

library(tidyverse)
USGDPpresidents %>%
  select(Year, Keynes, realGDPperCapita) %>%
  filter(!is.na(Year), !is.na(Keynes), !is.na(realGDPperCapita)) %>%
  ggplot(aes(y=Year,x=realGDPperCapita,color= as.factor(Keynes)))+
  geom_point()+
  scale_color_manual("Keynes", values = c("#270181", "coral"))
