Removing the frame from the Boxplot() function in R

Question

Does someone know how to remove the frame when producing a boxplot with the R boxplot() function?

With the plot() function there is an optinal argument, frame=F, that does the job... but it is not included in the boxplot() function...

Thank you very much!

Answer 1

Use the option frame=F (or frame.plot=F) in the boxplot function :

boxplot(count ~ spray, data = InsectSprays, col = "lightgray",frame=F)

Other parameters that can be used in the boxplot function are (rather inconveniently) listed on the helppage of ?bxp, which is the underlying function of boxplot()

Answer 2

You can do this with bty in par. Using an example from the boxplot help:

par(bty='n')
boxplot(count ~ spray, data = InsectSprays, col = "lightgray")

Answer 3

boxplot() seems to accept the frame argument just fine.

 boxplot(count ~ spray, data = InsectSprays, col = "lightgray")
 #vs    
 boxplot(count ~ spray, data = InsectSprays, col = "lightgray", frame = FALSE)
