![]() Ploting multiple graphs in single one page (or canvas) with classic R command is straightforward and easy. In this post I will show you how to arrange multiple plots in single one page with: Split.Multiple plots in one page Multiple plots in one page # Split screen 2 into one row and two columns, defining screens 6 and 7. Split.screen( figs = c( 1, 3 ), screen = 1 ) # Split screen 1 into one row and three columns, defining screens 3, 4, and 5. # Split the screen into two rows and one column, defining screens 1 and 2. See the code below, which is self explanatory because of comments. Thus we get 3 plots on top row, and 2 on bottom row, as we wished. If we now create 5 plots one by one, plots are placed from screen 3 to 7. We now split bottom screen (screen 2) into 2 columns to get screen 6 and 7: For example, command below splits screen 1 (top screen) into one row and three columns. We can further split the top and bottom screen again. Which splits the screen into 2 rows and 1 column. In this way, different rows can have different number of figures.Īs an example, suppose we want to place three figures along first row and two figures below them on the second row. Each row in turn is split into as many sections as required. This leaves a blank at the position of fifth plot.Īnother way of creating multiple plots on the same screen is by splitting the screen into regions and plotting. Forexample, in a 2x3 matrix of plots, if we want to skip the 5th plot and leave a blank there, call the 4 plots as usual, and during fifth plot, just call the plot.new() function. This can be achived using the call to plot.new() function. While plotting multiple plots using par(), sometimes we want to skip a plot in the matrix and leave a blank space in its location. Multiple curves on the same plot To skip a plot in par() Title("A visual summary of the results", outer=TRUE) # Title is given to the whole of the plot. Using Plot() And Points() Function In Base R: In this approach to create a scatter plot with multiple variables, the user needs to call the plot() function Plot() function: This is a generic function for the plotting of R objects. # Three Box-Whiskers are plotted, for x, y and x vectors # we create a list of vectors and call box plot with it. # The sixth plot is located in row 2, column 3 Pie(x = result, main="Figure-1(E)", col=rainbow(length(result)), # Create a Pie chart with a heading and rainbow colors # The fifth plot is located in row 2, column 2: ![]() # plot.new() skips a position, if needed. Plot( rpois(n=20, lambda=5), type = "h", col="purple", xlab="Poisson deviate : mean=5", Here, geombar () is used to draw the bar plot, geomline () is used to draw the line chart. A plot is generalized using ggplot () function and then all plots are added to the same plot using + sign. This again can be used to combine multiple graphs into one. # We generate 20 poinrs from a Poisson distribution and plot them. ggplot is a library supported by R which visualization easier. # "rnorm(10000)"generate a histogram of 10000 gaussian deviates Although creating multi-panel plots with ggplot2 is easy, understanding the difference between methods and some details about the arguments will help you make more effective plots. Plot(runif(100), runif(100), col="red", pch = 8, xlab="deviate-1", With a single function you can split a single plot into many related plots using facetwrap() or facetgrid(). # "runif(100)" returns 100 uniform random numbers between 0 and 1. # We generate 2 sets of 100 uniform random numbers and create their scatter plot. group) + geompoint() + geomline() + themebw() And heres what the graphs look like: You can also create a separate graph for each value of group: The code below will save all the graphs (one for each value of group) in a list called pl. This is drawn at the location row 1, column 2: Multiple panels: ggplot(dat.m, aes(x, value)) + facetgrid(. ![]() This is drawn at the location row 1, column 1: # To plot along columns, usde "mfcol" instead of mfrow. # outer margin for top is 2 lines of text. # Set the outer margin for bottom, left, and right as 0 and # Set up plotting in two rows and three columns. # This script demonstrates multiple plots in a single figure.
