[R] PowerPoint
Dear All, I am looking for the best way to use graphs from R (like xyplot, curve ...) for a presentation with powerpoint. I used to save my plot as pdf and after to copy them as image in powerpoint but the quality is not optimal by so doing. Another completely independent question is the following: when I use main in the xyplot, the main title is very close to my plot, i.e. no ligne separate the main and the plot.

Re: [R] PowerPoint
Bernard, there are some things that affect your graphs in MS Powerpoint like the formats you save and include them. You should consider test the various combinations. You should test the final presentation on the chosen presentation device 'cause there's some resolution variation there too. I use to save a .jpg format since I can control and test some resolution levels and include as image. For your main title, it's better you supply the group with some code in order we can help you more.

Dear Bernard, if you use MS Powerpoint, it seems likely to me that you are using the Windows version of R.

That way you get a vectorized version of the graph, which you can nicely paste into Powerpoint and edit.

Has anybody else on this list had a problem with lattice and win.metafile (or Ctrl-W in the R graphics device)? I will sometimes import wmf files (or Ctrl-V) with lattice graphics into powerpoint and notice some of the border lines are missing. I can re-size the plot to make the lines reappear but have to find just the right size to make it look right. This seems to be a problem with PPT, XLS, and Word. I never have this problem with traditional graphics (e.g. plot.default, etc.). I'm using Windows XP Pro with R-2.3.1 and lattice-0.13.8, though I've also experienced the problem on earlier versions of R and earlier versions of lattice.

Re: [R] PowerPoint
Has anyone tried this with OO.org's Impress or Writer on Windows to see if the same behavior occurs? My recollection from prior experience on Windows (it's been a while) is that a subtle resize takes place when pasting/importing graphics into the aforementioned apps. You can right click on the graphic in the app and then select Original Size or something worded similarly on the graphic object formatting dialog window. Not sure if that is enough to get the lines back or if one has to go slightly larger than the original size to resolve the issue. It also seems to me that there was some behavior on the R Windows graphic device relative to re-sizing the plot region and then doing the metafile copy and paste, but it has been long enough that my memory may not be intact (which my wife would suggest anyway ;-).

That is generally because png files are not compressed, whereas jpg files are. In fact, png uses a combination of pre-filtering and lossless compression (in contrast to lossy compression algortihms use in jpg). Of course, lossy compression can achieve much smaller file sizes for most images. While even a substantial loss of information can go undetected by the observer in the case of photographic images with no sharp edges, line drawings suffer badly. Line drawings usually contain vast percentages of empty space (i.e. white) and thus can be compressed quite effectively by the pre-filteing/lossless compression used by png. Anyway - I totally agree that eps rules and pixel formats should be avoided at all cost for illustrations, plots, etc. ... cu Philipp -- Dr. Philipp PagelTel. +49-8161-71 2131 Dept. of Genome Oriented Bioinformatics Fax. +49-8161-71 2186 Technical University of Munich Science Center Weihenstephan 85350 Freising, Germany and Institute for Bioinformatics / MIPS Tel. +49-89-3187 3675 GSF - National Research Center Fax. +49-89-3187 3585 for Environment and Health Ingolstädter Landstrasse 1 85764 Neuherberg, Germany http://mips.gsf.de/staff/pagel __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Re: [R] PowerPoint - eps not suitable
I think I was just comparing the ones that were discussed but certainly the vector format used on Windows is normally emf or wmf and that is what I would normally use too. On 6/23/06, Michael H.

Mike Just so that it is covered (though this has been noted in other threads), even in this situation, one can still use EPS files embedded in PowerPoint (or Impress) presentations. The scenario is to print out the PowerPoint presentation to a Postscript file (using a PS printer driver). If you have Ghostscript installed, you can then use ps2pdf to convert the PS file to a PDF file. If you have OO.org, there is a Distiller type of printer driver called PDF Converter (configured via the printer admin program) available, which you can use to go directly to a PDF in a single step. This also uses Ghostscript (-sDEVICE=pdfwrite) as an intermediary (though hidden from the user) step. The standard OO.org PDF export mechanism (using the toolbar icon) only exports the bitmapped preview, not the native EPS image. This is what you see as the preview image in these Office type of apps by default. Most PDF file viewers (Acrobat, xpdf, Evince, etc.) have a full screen mode, whereby you can the use the viewer to display the presentation in a landscape orientation to an audience. I have done this frequently (under Linux with OO.org) to facilitate presentations, when for any number of reasons, using LaTeX (ie. Beamer) was not practical. Even when using Beamer, the net result is still the same: creating a PDF file via pdflatex, which is then displayed landscape in a PDF rendering application full screen. This was the typical mode of operation at last week's useR! meeting in Vienna. All that being said, the ultimate test is in the eye of the user. So whatever gives you sufficient quality for your application with minimal hassle is the way to go.

Re: [R] PowerPoint
Hello,
IMHO,
for the printer
1 - The best choice of graphics format is postscript ( PS ) in
Microsoft ( M$ ), since you install the M$ Convert Pack [1]!
Make a preview in PS file with EMF format! use epstool for this
2 - Enhanced MetaFile ( EMF ) in M$ and OpenOffice ( OOo) is not the
same... This can be a problem! See pstoedit page [2]
3 - In OOo, I use the EPS file with the follow procedure:
- save my graphic in PS
- make to use de EPSTOOL for to produce EPS ( ps with tiff
preview
) - preview is a tiff graphic with low quality
*note: emf can be also to included for preview
- I need a PS-printer... in the case of NO-ps-printer, the
tiff
(low quality) will be printed! { :-( }, then, I make a PDF final
report
with ExtendendPDF!
- this procedure also work in the M$-Word
HTH,
Cleber N. Borges {klebyn}

Dear All,
I am looking for the best way to use graphs from R (like xyplot, curve ...)
for a presentation with powerpoint. I used to save my plot as pdf and after
to copy them as image in powerpoint but the quality is not optimal by so
doing.
Another completely independent question is the following: when I use main
in the xyplot, the main title is very close to my plot, i.e. no ligne
separate the main and the plot. I would like my title to be well
distinguished from the plots.
I would be grateful for any improvements...
Many thanks,
Bernard,

[R] PowerPoint graph insertion
Yes: I have Tufte's monograph on my desk. (along with 4 statistics texts) Yes: I am not the biggest fan of PowerPoint. Yes: I am using R to generate charts, plots, trends, etc. I have to summarize them each week. When I consider how to organize this data my first thought is to generate an HTML file with links to the R-generated plots, which HTML file organizes the plots in the required order. However: * Each week we annotate one PowerPoint slide in the weekly presentation with action items -- we don't only use PP as a presentation tool. This is convenient, as then the action items resulting from particular data trends are associated in a single document with the plots of the data trends. * Other (non-R) users insert data into the weekly PP presentation: from other plotting software and images from various sources (microscope, SEM, TEM, etc.), which I cannot easily incorporate into a generated HTML file before-the-fact. * I'm not sure how to create an HTML file which allows one to page forward and backward through it easily, as with PowerPoint (a minor point: and there is probably a way to write HTML to respond to such) So: Can R insert plots into an existing PowerPoint presentation? (actually, I'd copy last week's presentation and then update with new plots) I'll guess that it cannot, as there probably is not a Microsoft supplied interface (ODBC or otherwise) with PowerPoint as there is with Excel. -Leif Kirschenbaum, Ph.D. Sr. Yield Integration Engineer (I'm a physicist) [EMAIL PROTECTED] __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

You can do it in VBA or you can do it in R using the RDCOMClient or rcom packages, either of which provide an interface to Microsoft COM objects, in general (these are not specific to any particular application). I would first do it manually in PP with the macro recorder on so you can see what VBA code is generated by the recorder. Then you can use that as a base for your VBA code or if you like you can translate it to R using either of the above mentioned R packages. __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
