This function uses the following basic syntax: define plot area as four rows and two columns par (mfrow c (4, 2)) create plots plot (1:5) plot (1:20). Subplot <- function (fun, x, y = NULL, size = c(1, 1), vadj = 0.5, hadj = 0.5, You can use the par () function in R to create multiple plots at once. Only change the first 3 lines of the code, leave the other untouched (you can verify it by diffing this code and entering subplot into the R console). On the other side, if you want a quick solution, add the following code segment to your script (so it is shadowing the original function definition). If you manage to install version 2.8, the problem is solved automatically. A bit of Googling helped, my solution is based on this thread on the R-help list since October, 2010. However, there is a minor flaw in the code of version 2.7: when I wanted to use multiple plots on one layout (e.g., next to each other to use a common legend), it always drew the charts into the first plotting area. Well, the parameterization of the functions is a bit tricky but after a few tries you get used to it. I made a little survey and found that there is a TeachingDemos library in CRAN that fits my needs. Try the free first chapter of this interactive data visualization course, which covers combining plots.I’m in the middle of creating a poster and wanted to compresss the content by transforming some of the charts into subplots of other charts. You can use this to combine several plots in any arrangement into one graph. You have to experiment to get it just right.įig= starts a new plot, so to add to an existing plot use new=TRUE. Again, I chose a value to pull the right hand boxplot closer to the scatterplot. The right hand boxplot goes from 0.65 to 1 on the x axis and 0 to 0.8 on the y axis. I chose 0.55 rather than 0.8 so that the top figure will be pulled closer to the scatter plot. The top boxplot goes from 0 to 0.8 on the x axis and 0.55 to 1 on the y axis. The first fig= sets up the scatterplot going from 0 to 0.8 on the x axis and 0 to 0.8 on the y axis. The format of the fig= parameter is a numerical vector of the form c(x1, x2, y1, y2). To understand this graph, think of the full graph area as going from (0,0) in the lower left corner to (1,1) in the upper right corner. Mtext("Enhanced Scatterplot", side=3, outer=TRUE, line=-3) Plot(mtcars$wt, mtcars$mpg, xlab="Car Weight",īoxplot(mtcars$wt, horizontal=TRUE, axes=FALSE) In the following example, two box plots are added to scatterplot to create an enhanced graph. Creating a figure arrangement with fine control # column 2 is 1/4 the width of the column 1 # One figure in row 1 and two figures in row 2 Absolute widths (in centimetres) are specified with the lcm() function. Relative widths are specified with numeric values. Heights= a vector of values for the heights of rows. Widths= a vector of values for the widths of columns Optionally, you can include widths= and heights= options in the layout( ) function to control the size of each figure more precisely. Mat is a matrix object specifying the location of the N figures to plot. The layout( ) function has the form layout( mat ) where Plot(wt,disp, main="Scatterplot of wt vs disp")Ĭlick to view # 3 figures arranged in 3 rows and 1 column # 4 figures arranged in 2 rows and 2 columns mfcol=c( nrows, ncols ) fills in the matrix by columns. With the par( ) function, you can include the option mfrow=c( nrows, ncols ) to create a matrix of nrows x ncols plots that are filled in by row. R makes it easy to combine multiple plots into one overall graph, using either the
