Dear all I have trouble with setting the size for jpegs and pngs. I need to save a dendrogram of 1000 words into a jpeg or png file. On one of my computers, the following works just fine: bb<-agnes(aa, method="ward") jpeg("C:/Temp/test.txt", width=17000, height=2000) plot(bb) dev.off() On my main computer, however, this doesn't work...

Someone inquired on StackOverflow about apparently non-deterministic graphics behaviour in R. I noticed that they were using cex="*" and discovered some potentially weird behavior. On repeated runs of the same code I can get different PNGs. If I set the number of runs high enough, I seem to be able to get R to hang. If I do a single version plotting to an interactive graphics window I can get the point sizes to jump around as I resize the window (someone reported being able to reproduce that behaviour in the Windows GUI as well)....

I have a folder full of pngs and jpgs, and would like to consolidate them into a pdf with appropriate title and labels. Can this be done via R ? _________________________________________________________________ Easily publish your photos to your Spaces with Photo Gallery. [[alternative HTML version deleted]]

Dear list, i just encountered a problem concerning the export of multiple plots. is it possible to merge several PNGs into one PDF document? i know that this could be easily done by pdf(), but the outcome of this is /way/ too huge (> 15 MB, four plots) and to my knowledge there's no way to compress PDFs directly in R. Hence the PNGs that are saved one at a time and afterwards merged by Adobe Acrobat. Since...

I have noticed that xloadimage rpm is not in centos 5.1 I use the command "xview -identity" to get the size of gifs, jpgs, and pngs. xview is part of the xloadimage package. The command "file filename" also reports sizes for gifs and pngs BUT not for jpgs. Is there an alternative command to use to report gif jpg and png sizes? I thought about just getting an older xloadimage package and that works but I want to do...

If I have data: dat<-data.frame(a=rnorm(20),b=rnorm(20),c=rnorm(20),d=rnorm(20),site=rep(letters[5:8],each=5)) And want to plot like this: ctr<-1 for(i in c('a','b','c','d')){ png(file=paste('/tmp/plot_number_',ctr,'.png',sep=''),height=8.5, width=11,units='in',pointsize=9,res=300) print(ggplot(dat[,names(dat) %in%

Hello all, I am using quartz (on OS X obviously) to produce PDFs and PNGs from my plots, for later inclusion in LaTeX. I am typically using something like: plot(0) dev.print(quartz, file="foo.pdf", width=5, height=3) dev.print(quartz, file="foo.png", width=5, height=3, dpi=72) I want the sizes of the PDF and PNG to be *equal* in *inches*, which wor...

Hello, i only got a small problem. i try to create automatic new dataframes, or png?s. the main problem i got is: how can i create automatic a new name for a file (read out by simply "for") - i tried to use "(paste...) but theres an errormessage, about a wrong declination. R told it is as.character, but need as.Real. Should i use another method than "paste"? i tried as

...ng PDF files are slightly smaller, but still too large, and PDF viewers still don't like it. So I gave PNG a try. PNG files are much smaller and PDF viewers have no trouble with them. However, fonts look ugly. The same trick that worked for Cairo PDF has no effect for PNG. When I view the PNGs with a dedicated viewer like 'qiv', even the fonts look good. But not when included in LaTeX; I simply use '\includegraphics{...}' and run the document through 'pdflatex'. I tried both, creating PNG with 'png(...)' and converting from PDF to PNG using 'conver...

I've just been trying to post-process some R-created heatmaps using Inkscape, but I can't get them to display correctly in that software. To reproduce: library(grid) r <- as.raster(matrix(runif(25), 5, 5)) pdf("test.pdf") grid.newpage() grid.raster(r, interpolate = FALSE) dev.off() This figure should be a five by five block of grey squares. This is what I see in the R GUI

Hello, I'm trying to run R from a webserver, which doesn't have an X server, and produce pngs to go on a webpage, is this possible? I'm doing it in gnuplot with gnuplot> set term png gnuplot> set output With $DISPLAY unset, I get the following error from R: > png() Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable...

Dear all, is there a possibility to display pictures (jpegs, pngs, ...) in R? Maybe the following (hypothetical) code makes it clearer what I have in mind: plot(x=0:100, y=0:100, type="n") rect(xleft=25, xright=75, ybottom=30, ytop=95, fill="apicture.png") Thank you, Roland [[alternative HTML version deleted]]

I have successfully installed ADaCGH package, and trying the example in SegmentPlotWrite did produce alot of pngs and html. I tried again the same example this morning (after a long night of installation), ADaCGH crashes at mpiInit() showing the error: Loading required package: Rmpi ELAN_EXCEPTION @ --: 6 (Initialisation error) elan_init: Can't get capability from environment Aborted I suspect the clu...

Hi, I am trying to generate plots on our unix (no X) server to be included in our web-pages -> specifically pngs. Without X, png() obviously doesn't work, so I have been trying to define the graphics print device bitmap as described in the help: > bitmap(file="plot.png", type = "png256", height = 6, width=6,res=72) > pie(c(12,5)) > dev2bitmap(file="plot.png", t...

...le? Can you open a wine-translation mailing list, translation and writing c code are two very different things, and it would be better to have a separate mailing list. ?And I still don't know what to do about images, I've translated the home page and the about page into italian, but all the pngs are still in English, and as I can't edit the images, i think we should find a graphics expert that can do that, finally, most people I know that can translate don't know what CVS is, and probably don't want to learn how to use it, it would be more simple to just have a FTP publishing s...

I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I''ve used GDChart in the distant past but...

Hello. I have made many pngs in the past, but started having trouble with them yesterday. I just downloaded R 2.13.0 this morning, and was able to make some pngs earlier this morning. Now I am trying to remake them, but get the same error message I got yesterday: > u='in' > w=10.5 > h=8 > png('winbug...

...#39;ve searched the list, and I can't find reference to this being implemented: reverse veto files - a list of files *allowed* rather than the current list of files *denied*. Possibly implemented by just allowing a ! in the veto files directive. eg: veto files = /!*.png/!*.gif/ = only allow pngs and gifs to be read or written through that share. (though that's probably not the best syntax) I still think it's a good idea that I would find really valuable. Was this discussed further? Has it been implemented under another directive that I've missed? Has my google-foo let me dow...
