How to place boxplot side by side?

Question

Here's part of my data:

I would like to place box plots of "Maintain.Diverse..Functional", "Maintain.Focal.Rare", and "Restore.Habitat.Structure" side by side. I tried this:

boxplot(A$Maintain.Diverse..Functional, ylab="ranking", xlab="Maintain.Diverse..Functional")

But I only get one box plot, I was wondering how to add two other boxplots side by side with the same scale?!

data

structure(list(Maintain.Diverse..Functional = c(1, 1, 1, 2, 1, 
4, 4, 1, 4, 4, 7, 3, 6), Maintain.Focal.Rare = c(2, 3, 3, 4, 
2, 3, 1, 2, 1, 3, 2, 1, 1), Restore.Habitat.Structure = c(3, 
5, 2, 3, 3, 1, 2, 3, 2, 2, 6, NA, 3)), .Names = c("Maintain.Diverse..Functional", 
"Maintain.Focal.Rare", "Restore.Habitat.Structure"), row.names = c(NA, 
-13L), class = "data.frame")

Hi Wendy, can you add the actual data as code please ... you can do this by editing your question with, for example, `dput(yourdata[1:10, 1:3])`, where `yourdata` is the name of the dataframe, and `1:3` gives the first three columns (change if needed). thanks — user20650, Jul 24 '15 at 21:29
Does `boxplot(yourdata[c("Maintain.Diverse..Functional", "Maintain.Focal.Rare", "Restore.Habitat.Structure" )])` do what you want? — user20650, Jul 24 '15 at 21:34

It works when I typed this:

boxplot(yourdata[c("Maintain.Diverse..Functional", "Maintain.Focal.Rare", "Restore.Habitat.Structure" )])

Thank you @user20650 for your answer!

You can create each box plot separately say box1, box2, box3.

With the gridExtra package, you can arrange them like:

grid.arrange(box1, box2, box3, ncol=3)
