Save the output (File: Save, or similar) There are several problems with this approach: 1. We can convert R plots into high-quality PNG, JPEG, TIFF bitmap files, high resolution PDF files with embedded fonts, SVG graphics and PostScript files. It is therefore funny that exporting these plots is such an issue in Windows. I eventually found that R can’t figure out the other image parameters when resolution is changes or because the default is too big to print, so they have to be specified directly as such: This creates a TIFF file that is 5,800 KB, 300 ppi, 4 inches by 4 inches. Finally, the PGRAF subroutine plots the observed and predicted values by using the corresponding symbols, as shown in Figure 4.9. plotlist (optional) list of plots to display.
