In ptl93/AEDA: Automated Exploratory Data Analysis

Description

Arranges ggplot objects into a grid

Usage

multiplot(..., plotlist = NULL, cols = 1, layout = NULL)

Arguments

...	If ggplot objects are not handed over as a list, insert them manually
plotlist	[list()] A list of ggplot objects. Default is plotlist = NULL
cols	[integer(1)] Number of columns for the grid
layout	[matrix()] A matrix specifying the layout. If present, cols is ignored.

Examples

library(ggplot2)
p1 = ggplot(ChickWeight, aes(x = Time, y = weight, colour = Diet, group=Chick)) +
  geom_line() +
  ggtitle("Growth curve for individual chicks")

# Second plot
p2 = ggplot(ChickWeight, aes(x = Time, y = weight, colour = Diet)) +
  geom_point(alpha = 0.3) +
  geom_smooth(alpha = 0.2, size = 1) +
  ggtitle("Fitted growth curve per diet")

# Third plot
p3 = ggplot(subset(ChickWeight, Time == 21), aes(x = weight, colour = Diet)) +
  geom_density() +
  ggtitle("Final weight, by diet")

# Fourth plot
p4 = ggplot(subset(ChickWeight, Time == 21), aes(x = weight, fill = Diet)) +
 geom_histogram(colour = "black", binwidth = 50) +
 facet_grid(Diet ~ .) +
 ggtitle("Final weight, by diet") +
 theme(legend.position="none")
#multiplot the ggplots
multiplot(p1, p2, p3, p4, cols = 2)
