R中的自动绘图功能和绘图功能有什么区别

Question

这两个功能有什么区别

plot(AP,xlab="Date", ylab = "Passenger numbers (1000's)",main="Air Passenger numbers from 1949 to 1961")

autoplot(AP) + labs(x ="Date", y = "Passenger numbers (1000's)", title="Air Passengers from 1949 to 1961") 

Answer 1

从图形数据表示的角度来看，graphics::plot和ggplot2::autoplot + ggfortify软件包之间的时间序列绘图没有太大区别。如果您将开始绘制更复杂的图（构面，多图，分组等），则差异将显而易见。至于您的问题，请参见下文：

graphics :: plot ：

data(AirPassengers)
AP <- AirPassengers
plot(AP, xlab="Date", ylab = "Passenger numbers (1000's)", main = "Air Passenger data, base")

ggplot2 :: autoplot ：

library(ggplot2)
library(ggfortify)
data(AirPassengers)
AP <- AirPassengers

autoplot(AP) + 
  labs(x ="Date", y = "Passenger numbers (1000's)", title = "Air Passengers from, ggplot2")
