multiPlot: Plotting of multiple objects in a single window

In AFMSAnalytics/utilityScripts: Useful functions for easier R use

Description

The multiPlot() function is meant to make plotting of multiple plot objects easier and more straightforward. Adapted from Winston Chang's "Cookbook for R".

Usage

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

Arguments

plotlist	A vector list of plot objects, e.g. c(plot1, plot2, ..., plot_n).
cols	Number of columns in layout.
layout	A matrix specifying the layout. If present, 'cols' is ignored.
file

Examples

usePackage("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)
