Hi Dennis Out of curiosity, how did you import the pdf to Power Point? I am running windows so it may be different (and completelly irrelevant to you!) but when I want to place a pdf image in a PPT slide I copy the file to the clipboard and then paste it in Power Point. Then in Power Point you can right click on the image-> show picture toolbar and then use the tool "Set Transparent Color". That will give you a transparent background but you may not get be the best quality, so in general I prefer to save the image as a bmp or some other format and then insert that into Power Point directly using the Insert menu in PPT.
I hope this helps Francisco >From: Jari Oksanen <[EMAIL PROTECTED]> >To: Dennis Fisher <[EMAIL PROTECTED]> >CC: r-help@stat.math.ethz.ch >Subject: Re: [R] "transparent" background for PDF >Date: Fri, 24 Mar 2006 21:11:52 +0200 > > >On 24 Mar 2006, at 20:30, Dennis Fisher wrote: > > > Colleagues > > > > Running R2.2.1 on either a Linux (RedHat 9) or Mac (10.4) platform. > > > > I created a PDF document using pdf("FILENAME.pdf", bg="transparent", > > version="1.4").
