R Multipanel Plots

Built-in Plotting

# 4 figures arranged in 2 rows and 2 columns
attach(mtcars)
par(mfrow=c(2,2))
plot(wt,mpg, main="Scatterplot of wt vs. mpg")
plot(wt,disp, main="Scatterplot of wt vs disp")
hist(wt, main="Histogram of wt")
boxplot(wt, main="Boxplot of wt")

ggplot2/gridExtra

Have to install gridExtra first.

install.packages("gridExtra")
library(ggplot2)
library(gridExtra)
p1 <- qplot(mpg, wt, data = mtcars, colour = cyl)
p2 <- qplot(mpg, data = mtcars) + ggtitle("title")
p3 <- qplot(mpg, data = mtcars, geom = "dotplot")
p4 <-
  p1 + facet_wrap( ~ carb, nrow = 1) + theme(legend.position = "none") +
  ggtitle("facetted plot")

grid.arrange(p1, p2, p3, p4, nrow = 2)

Plotly

library(plotly)
p1 <- plot_ly(economics, x = ~date, y = ~unemploy) %>%
  add_lines(name = ~"unemploy")
p2 <- plot_ly(economics, x = ~date, y = ~uempmed) %>%
  add_lines(name = ~"uempmed")
subplot(p1, p2)
