Hi, I really like the nice vector-based pdf graphics I get in R. However, PowerPoint seems to be unable to read them as vector graphics and rasterizes them, making them quite "fuzzy" and ugly. Granted, the problem lies with Microsoft, but in the mean time what is the best workaround? I'd like to do better than producing png from within R (especially that only my iMac has X11, my very old PowerBook does not). I am still able to show vector graphics in pict format in PowerPoint. So it should be possible to extract the vectorized plot from the pdf and save it as pict, still vectorized. However opening the R-produced pdf in Illustrator and saving as pict produces a file quite a bit bigger than the original pdf, suggesting it was saved as raster pict instead of vector pict. It shows up in Powerpoint just as ugly as if it was inserted directly as pdf. This is true with Illustrator CS (aka v11 I think) used either under 10.2.8 or 10.3.7. It is also true when using GraphicConverter 5 and Preview (Jaguar's version, I think it is also true with the Panther version) to go from pdf to pict. I fired up Canvas (old, version 8) and it did manage to save something that was vectorized (i.e. very sharp when viewing at 400% in PowerPoint) but the empty circles I used as symbols were not filled blacks, the dashes of dashed lines had become "wiggly", text orientation was unacceptably changed, etc. etc. So does anyone know of a technique to produce vector graphics that insert nicely in PowerPoint, either directly from R or by converting a pdf produced by R into something else?

After similar struggles I have resorted to PNG for insertion in PowerPoint on the Mac. At, say, 500x600 pixels, PNG works quite nicely even though it isn't a vector format. (I've also used PNG in LaTeX-based presentations for plots that would otherwise take several seconds for Preview to render. The results are better in LaTeX, but ok in PowerPoint). -thomas
Denis - I use the following rather convoluted method with OS 10.3.8, Illustrator CS, and R2.0.1. command-c copies a figure from the quartz window. Open this file in preview and export it as a pdf file (don't know why i do this....). use illustrator, and the command <place> from the file menu to insert it in a new document. Choose <save for microsoft office> from the file menu in illustrator. this produces a png file that plays nicely, cross platform, with Word and PP. variations abound, but the goal is to get something presentable in illustrator and use its save for office option..... I noticed that preview has a png choice from export, but I've not yet played around with its options to see if I can get the same quality that the save for Microsoft Office option produces in Illustrator.

Thank you Andrew and Thomas, I have used png produced by Illustrator in much the way you described and the results were not very good. I'll try again because I don't remember if I was given an option to chose the overall size in pixels. If I can, then I'll increase the count. Alternatively, on my iMac at home where R11 is installed, I'll resort to saving directly in png but increasing the pixel count, as suggested by Thomas. Still, if the information in the pdf produced by R is vector based (it is still perfectly sharp when viewed at 1600% in Acrobat), why can't I find a way to transform such pdf in vector-based pict? That format must be able to handle such plots. After all, I also make plots in KaleidaGraph, and they were very small vector-based pict files. They looked gorgeous in Powerpoint at any zoom setting. I also use Aabel which gives you the option of saving plots as pdf or pict. I chose the later when I need to insert in PowerPoint, and the former for LaTeX. Quality is good either way. Maybe I'll check if there is a "graphics" discussion on Apple's site. If I manage to learn something useful I'll report back.

You can load the pdf file produce by R in the standard Previewer of Mac OS X and export to (almost) whatever format you like including bitmaps stefano

Hi Stefano, Bitmaps is what I'd like to avoid. Preview seems to be using QuickTime for the translation from pdf to pict, and the result is bitmap. Too bad though. Denis Le Jeudi, 10 f?vr 2005, ? 18:05 Europe/Paris, stefano iacus a ?crit :

yes, but as Thomas pointed out png is not that bad even with LaTeX. What kind of vectorial format does PowerPoint support (if any) ? I'm not used to PowerPoint, but for example, with KeyNote (the apple counterpart) you can use pdf graphics directly and you still have an option to export the slides in PowerPoint.

well, if you can afford it: the Power Point look-alike from apple
("Keynote") can usually import _and_ export .ppt files (so you can at
least use what you already have). but if you present your results with a
mac (and with Keynote) your problem is solved, since you can simply drag
adn drop your pdf file into the keynote slides which keeps it as such
(i.e. vector graphics). all in all keynote (if it survives...) seems to
be a much nicer thing than power point.
I am still able to show vector graphics in pict format in PowerPoint. So it should be possible to extract the vectorized plot from the pdf and save it as pict, still vectorized.

AFAICS there is no way to include vector graphics into PP other than WMF (and I didn't even test that on a Mac). OT: Get Apple Keynote - it's far better, pastes such PDFs in vector form flawlessly and it even supports copy/paste of Latex formulas in vector form (via LaTeX Equation Editor)! There are plenty output formats if you really need to present it on a PC, too... Cheers, Simon
Hi All, My guess is the supported vector format is Windows enhanced meta file, which R for Windows will produce. Unfortunately, Microsoft Office is the one thing most of us can't get away from, try as we might. As a result, an argument could be made to have a device for this format on the Mac side if the Windows code could easily be ported. Dan

It is also true when using GraphicConverter 5 and Preview (Jaguar's version, I think it is also true with the Panther version) to go from pdf to pict. I fired up Canvas (old, version 8) and it did manage to save something that was vectorized (i.e. very sharp when viewing at 400% in PowerPoint) but the empty circles I used as symbols were not filled blacks, the dashes of dashed lines had become "wiggly", text orientation was unacceptably changed, etc. etc. So does anyone know of a technique to produce vector graphics that insert nicely in PowerPoint, either directly from R or by converting a pdf produced by R into something else?

I would love to get Keynote, but it is not compatible with my old powerbook. As my employer had put a freeze on computer purchases because of budget constraints (and because buying a Mac where I work is a big struggle, as I'm seen as a thorn in the (chose your soft spot) of the IS guys who'd love to have a 100% Windows universe, but that's another story) it is not an option (yet). Actually in recent versions of PowerPoint wmf usually display properly and very sharp. In a presentation I gave yesterday the only sharp graphs came from wmf maps I produced with Surfer on a Windows machine, what a shame! But I can certify that PowerPoint always allowed vector pict format. For now I'll have to resort on running some R programs a second time and save higher resolutions png than what Preview and Illustrator give me when they translate pdf into png.

AFAICS there is no way to include vector graphics into PP other than WMF (and I didn't even test that on a Mac). OT: Get Apple Keynote - it's far better, pastes such PDFs in vector form flawlessly and it even supports copy/paste of Latex formulas in vector form (via LaTeX Equation Editor)! There are plenty output formats if you really need to present it on a PC, too... Cheers, Simon
Well it would be more logical for Microsoft to support pdf! I've certainly complained loud enough, but I don't count on them doing something for me. Unless pdf becomes important on Windows, I suppose. As for a R-based solution, a pict device would solve my problem just as well as a wmf device. Denis Le 10 f?vr. 2005, ? 19:04, Dan Putler a ?crit :
Hi All, My guess is the supported vector format is Windows enhanced meta file, which R for Windows will produce. Unfortunately, Microsoft Office is the one thing most of us can't get away from, try as we might. As a result, an argument could be made to have a device for this format on the Mac side if the Windows code could easily be ported. Dan On Thu, 2005-02-10 at 09:20, stefano iacus wrote:

yes, but as Thomas pointed out png is not that bad even with LaTeX. What kind of vectorial format does PowerPoint support (if any) ? I'm not used to PowerPoint, but for example, with KeyNote (the apple counterpart) you can use pdf graphics directly and you still have an option to export the slides in PowerPoint.

Thank you Andrew and Thomas, I have used png produced by Illustrator in much the way you described and the results were not very good.

Unfortunately it cannot be easily ported, because creating WMF in Win is trivial - Windows generates it for you (more precisely you draw the same way as if it was screen or printer - actually the same way you get PDF on a Mac ;)). Since it's Windows creating the WMF and not R, you cannot port it unless you implement what Windows does... I was looking into generating WMF from scratch long time ago and at that time there was no (non-commercial) library for writing WMF files. At that point libwmf was strictly read-only and I didn't check whether they added write-support which was planned for the future .. [btw: I'm using WMF here in the sense of both EMF and WMF]. If no one else tackles this and I have a spare minute, I 'll have a look if we can cook anything out of that ... Cheers, Simon

Definitely, but M$ never does anything based on whether it makes sense - they do whatever will tie their users even more to M$ - which is keeping WMF to be the only format they support :).
As for a R-based solution, a pict device would solve my problem just as well as a wmf device.
I suspect that PICT is too legacy a format, but with some luck there may be a way to export Quartz to PICT ... I'll give it a shot (being a Mac user only since OS X I didn't know of vector PICT ...). Cheers, Simon
A search for PDF to WMF gives me, among the others http://www.business-presentations.co.uk/tranpro.htm stefano
