How to add stripchart on a boxplot without outliers?

Question

I made a boxplot without outliers.

boxplot(data, names = names(files), las = 2, outline=FALSE)

Now, I am trying to add stripchart on it:

stripchart(data, method = "jitter", add = T, col = "red")

Plot looks something like this:

I understand the reason why plot is like this: because I have not plotted outliers with boxplot. How to add stripchart properly (without outliers)?

Why not considering first filtering those outliers from data? — Eric Lecoutre, Jun 17 '16 at 15:19

It isn't clear what you want the plot to look like, or what the problem is here. — gung - Reinstate Monica, Jun 17 '16 at 15:28

I have solved my problem.

b <- boxplot(data, names = names(files), las = 2, outline=FALSE)
stripchart(data[!data %in% b$out], method = "jitter", add = T, col = "red",
           vertical = T)
