How do you add a line segment to a stripchart in R?-CodePudding

This is likely a very easy question, but I'm not great with R and haven't found a simple answer elsewhere on the internet.

I want to add a line segment connecting the two points in this stripchart, but cannot figure out how to do so.

stripchart(c(0.5, 1.5), pch = " ")

Any help would be much appreciated!

CodePudding user response：

Create a data frame or vectors with the coordinates for the line and plot with lines

df1 <- data.frame(x = c(0.5, 1.5),
                  y = 1)

stripchart(c(0.5, 1.5), pch = " ")
lines(df1$x, df1$y)
