facet_wrap in ggplot2

How to make subplots with facet_wrap in ggplot2 and R.

New to Plotly?

Plotly's R library is free and open source!
Get started by downloading the client and reading the primer.
You can set up Plotly to work in online or offline mode.
We also have a quick-reference cheatsheet (new!) to help you get started!

Version Check

Version 4 of Plotly's R package is now available!
Check out this post for more information on breaking changes and new features available in this version.

Basic Columns

library(reshape2)
library(plotly)

p <- ggplot(tips, aes(x=total_bill, y=tip/total_bill)) + geom_point(shape=1)

# Divide by day, going horizontally and wrapping with 2 columns
p <- p + facet_wrap( ~ day, ncol=2)

p <- ggplotly(p)

Add Unique Curves

## read in data set (tolerance data from the ALDA book)
tolerance <- read.table("https://stats.idre.ucla.edu/wp-content/uploads/2016/02/tolerance1_pp.txt",
    sep = ",", header = TRUE)

## change id and male to factor variables
tolerance <- within(tolerance, {
    id <- factor(id)
    male <- factor(male, levels = 0:1, labels = c("female", "male"))
})


p <- ggplot(data = tolerance, aes(x = time, y = tolerance)) + geom_point() +
    stat_smooth(method = "lm", se = FALSE) + facet_wrap(~id)

p <- ggplotly(p)

df <- diamonds[sample(1:nrow(diamonds), size = 1000), ]

# Create labels
labs <- c("Best","Second best","Third best","Average", "Average","Third Worst","Second Worst","Worst")
levels(df$clarity) <- rev(labs)

p <- ggplot(df, aes(carat, price)) + 
  geom_point() + 
  facet_wrap(~ clarity)
