To save the graphs, we can use the traditional approach (using the export option), or ggsave function provided by the ggplot2 package. ggplot2 offers ggsave() To be written. Look at the help file. grid.aarange( ), however, directly plots on a graphics device. Applies only to raster output types. With respect to [ggplot2::ggsave()], this function checks the types and swaps the filename and plot arguments if needed, so it is pipeable ... or "mm"). Embedding fonts in PDFs is also fairly easy. Save a ggplot (or other grid object) with sensible defaults, ggsave() is a convenient function for saving a plot. Instead of using R’s default PDF-writing engine, you can use the Cairo graphics library (which, nowadays, is conveniently packaged with R). Therefore, it is best practice to open your desired graphics device explicitly, using any necessary arguments to control height, width, fonts, etc. It’s also possible to make a ggplot and to save it from the screen using the function ggsave(): # 1.

Formatted, high-resolution ggplot2 figure ggsave is a convenient function for saving the last plot that you displayed. Then all the plots are put into that device. ggsave(filename="gg-higher-res.png", plot=ggplot_example, device="png", path=path, dpi=500) This still looks great! Description. arrangeGrob is in “gridExtra” package. It defaults to saving the last plot that you displayed, using the size of the current graphics device. Ggsave. It also guesses the type of graphics device from the extension. ggsave() is a convenient function for saving a plot. It also guesses the type of graphics device from the extension. The default is to save the last plot created in the format determined by the file extension at size of the current graphics device. Attempt 1: Use vector graphics The discussion above is especially relevant to raster output since they don’t resize gracefully and it is thus very important to get the correct dimensions and resolution when it is rendered. The last step is important, as you can’t open the file until the device is turned off. It also guesses the type of graphics device … To make ggsave() use the Cairo engine when writing a PDF, specify the device: The R ggplot2 package is useful to plot different types of charts and graphs, but it is also essential to save those charts. ggsave() is a convenient function for saving a plot. Finally, the device is turned off with dev.off(). limitsize. You can adjust all these in the ggsave command. dpi. ... and save things via ggsave(). It defaults to saving the last plot that you displayed, using the size of the current graphics device. Cairo has full Unicode support and can handle embedding custom fonts just fine. Plot resolution.
