multiplot {bbnet}

Multiplot function

Description

This function allows for the arrangement and display of multiple ggplot2 plots on a single graphics page.

Usage

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

Arguments

...

One or more ggplot2 objects to be plotted.

plotlist

An optional list of ggplot2 objects. This parameter can be used in conjunction with or instead of the direct plot arguments.

file

A path to save the output file.

cols

Specifies the number of columns in the grid layout if layout is not provided. Defaults to 1.

layout

An optional matrix specifying the layout of plots. Overrides cols if provided.

Details

multiplot() can take any number of plot objects as arguments, or if it can take a list of plot objects passed to plotlist.

multiplot() is built under CC0 licence from:

http://www.cookbook-r.com/Graphs/Multiple_graphs_on_one_page_(ggplot2)/

ggplot2 objects can be passed in ..., or to plotlist (as a list of ggplot2 objects)

Details:

• cols: Number of columns in layout.

• layout: A matrix specifying the layout.If present, cols is ignored.

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

plot

Examples

# Load necessary library
library(ggplot2)

# Create example ggplot objects
plot1 <- ggplot(mtcars, aes(x=mpg, y=wt)) + geom_point()
plot2 <- ggplot(mtcars, aes(x=mpg, y=cyl)) + geom_point()
plot3 <- ggplot(mtcars, aes(x=gear, y=wt)) + geom_point()

# Plot all three plots in a single row
multiplot(plot1, plot2, plot3, cols=3)

# Plot using a custom layout
layout_matrix <- matrix(c(1,2,3,3), nrow=2, byrow=TRUE)

multiplot(plotlist=list(plot1, plot2, plot3), layout=layout_matrix)
