However, this option is not reproducible since it leaves no enduring record. This allows for us to see how the image will look before we save it. One strategy we could take to size our plots is to adjust the Plots pane. Notice that the result of dev.size() and the message we receive when saving the plot with ggsave() give the same dimensions. Ggsave("plot.pdf") # Saving 7 x 5 in image dev.size() # 7 5 ggplot(mtcars, aes(x = wt, y = mpg)) + It will be saved as a pdf file, which you can double click to open in Preview, and then use the File -> Save As menu choice to convert to another format.The default size of the saved image is equal to the size of Plots pane (the “graphics device”) in RStudio, which can be found with dev.size(). On a Mac, click on the graphics window to make sure it's the active one, then go to File -> Save in the menubar, and choose a location to save the file. " If using Word, make sure to save as a metafile. Under Windows, right click inside the graph window, and choose either " Save as metafile. 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. 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. ![]()
