Draw label as a rectangle with edges rather than with rounded corners-CodePudding

Using geom_label() in ggplot2, is it possible to make the rectangle perfectly square rather than with rounded corners?

data(iris)

ggplot(iris, aes(Sepal.Width, Sepal.Length))   geom_point()   
geom_label(x=4, y=7, label = "Test label")

I want to square up the rounded rectangle around Test label.

Thanks.

CodePudding user response：

Yes you can set the label.r parameter to 0.

library(ggplot2)

ggplot(iris, aes(Sepal.Width, Sepal.Length))   geom_point()  
  geom_label(x=4, y=7, label = "Test label",
             label.r = unit(0, "pt"))
