not using ssh to connect), the graphical user interface makes it easy to save files. If you're actually sitting in front of a Windows or Mac computer (i.e. Remember that when you save plots this way, the plot isn't actually written to the file until you call dev.off.

#INSEER GRAPH R MARKDOWN DRIVER#

When you're happy with the way it looks, call dev.copy, passing it the driver you want to use, the file name to store it in, and any other arguments appropriate to the driver.įor example, to create a png file called myplot.png from a graph that is displayed by R, type > dev.copy(png,'myplot.png') To use this approach, first produce your graph in the usual way. For most plots, things will be fine, but sometimes translating what was on the screen into a different format doesn't look as nice as it should. R also provides the dev.copy command, to copy the contents of the graph window to a file without having to re-enter the commands. If you follow the process in the previous section, you'll first have to make a plot to the screen, then re-enter the commands to save your plot to a file. So if I wanted to save a jpg file called ' rplot.jpg' containing a plot of x and y, I would type the following commands: > jpeg('rplot.jpg') This is very important - without it you'll get a partial plot or nothing at all.

When you're done with your plotting commands, enter the dev.off() command.

You will not actually see the plot - the commands are being saved to a file instead.

Now enter your plotting commands as you normally would.

Consult the help file for your selected driver to learn how.

You may want to make adjustments to the size of the plot before saving it.

You can find the current directory by typing getwd() at the R prompt. Remember that your plot will be stored relative to the current directory.

The only argument that the device drivers need is the name of the file that you will use to save your graph.

In this example, I'll save a plot as a JPG file, so I'll use the jpeg driver.

Choose the format that you want to use.

Windows only best choice with Word easily resizableīest choice with pdflatex easily resizableīest choice with latex and Open Office easily resizableįirst, here's a general method that will work on any computer with R, regardless of operating system or the way that you are connecting. The following table lists some of the available formats, along with guidance as to when they may be useful.

#INSEER GRAPH R MARKDOWN HOW TO#

The first step in deciding how to save plots is to decide on the output format that you want to use. Since R runs on so many different operating systems, and supports so many different graphics formats, it's not surprising that there are a variety of ways of saving your plots, depending on what operating system you are using, what you plan to do with the graph, and whether you're connecting locally or remotely.
