Hi Rich,
Seems to work for me using Powerpoint in MS Office 2011 for Mac.
I used the following code:
postscript(file = "file.eps", height = 4, width = 4,
horizontal = FALSE, onefile = FALSE, paper = "special")
plot(rnorm(20))
dev.off()
Then I used the insert picture from file function in Powerpoint. It created the
PNG preview during import and I can see that on the slide in the application
without issue.
I put the EPS file and the PPTX file up on DropBox if you want to look at them:
EPS File: https://www.dropbox.com/s/d8avze4yv51blso/file.eps
PPTX file: https://www.dropbox.com/s/pm7oejm0g6rc0a5/RPlot.pptx
Regards,
Marc
