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

It is the PNG bitmapped image that you can see when displaying the EPS file in the document, hence the degradation in quality. Some years ago, all you would see is a rectangular box with an "X" across it, as a placeholder for the imported image.
