Hi all,
I'm producing some pie charts (Yes I know!) and plotting them into a Windows metafile. This is for insertion into a Word document.
The circles come out rather jagged when you zoom in on them, the cause of which I have perhaps narrowed down to the way polygon() works in the metafile device. The polygon coordinates seem to be quantised to the pixels, which is odd for a vector graphics format.
Try this to see what I mean:
win.metafile('test.emf')
par(mfrow=c(2,2))
for(i in 1:4) pie(sample(5,4,repl=TRUE))
dev.off()
Is there a way to get a better quality EMF file of this output? PDF output looks great, but Word doesn't seem to understand inserting a PDF graphics file. Word also did something strange with EPS output.
You should be able to insert the PDF version into Word
with 'Insert Object'. I don't know if it'll improve the
look. Does setting pie(..., edges=1000) help?
