multiplot: Multiple plot function

In gugl58/basicscriptsGG-Package: Includes the basicscripts for GG's analysis

Description

ggplot objects can be passed in ..., or to plotlist (as a list of ggplot objects) - cols: Number of columns in layout - layout: A matrix specifying the layout. If present, 'cols' is ignored.

Usage

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

Arguments

...	See description
plotlist	See description
file	See description
cols	See description
layout	See description

Details

If the layout is something like matrix(c(1,2,3,3), nrow=2, byrow=TRUE), then plot 1 will go in the upper left, 2 will go in the upper right, and 3 will go all the way across the bottom.

Value

multiple plots

Examples

library(ggplot2)

# This example uses the ChickWeight dataset, which comes with ggplot2
# First plot
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=.3) +
	geom_smooth(alpha=.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")        # No legend (redundant in this graph)

	multiplot(p1, p2, p3, p4, cols=2)
