14.3 Outputting to WMF Vector Files
14.3.1 Problem
You want to create a Windows metafile (WMF) image of your plot.
14.3.2 Solution
WMF files can be created and used in much the same way as PDF files – but they can only be created on Windows:
win.metafile("myplot.wmf", width = 4, height = 4)
plot(...)
dev.off()
# With ggsave()
ggsave("myplot.wmf", width = 8, height = 8, units = "cm")
14.3.3 Discussion
Windows programs such as Microsoft Word and PowerPoint have poor support for importing PDF files, but they natively support WMF. One drawback is that WMF files do not support transparency (alpha).
