在 R 中的散点图上绘制新点

Question

如何将变量x得到的点插入到代码1生成的散点图中？

我正在输入两个代码：第一个代码生成散点图。第二个代码是我想插入到这个生成的散点图中的新点。如果可能，将球保留为红色以与第一个球区分开来。

非常感谢！

代码 2

x <- subset(data, select = DR03:DR06)
x<-cbind(data, setNames(data$D1 - x, paste0(names(x), "_PV")))
x<-subset(x,select = DR03_PV:DR06_PV)

Answer 1

我认为y轴限制不够...通过使用graphics::points

library(graphics)

xx <- x %>%
  pivot_longer(everything(), names_pattern = "DR(.+)_PV", values_to = "val") %>%
  mutate(name = as.numeric(name))
graph("2021-04-09",dummy)
points(xx$name, xx$val, col = "red")
