Dear List, I am using the bioconductor package Category to do some gene enrichment analysis, and usually save my KEGGmnplot's using a dev2bitmap command. This has worked just fine, until suddenly earlier today I got this error-message: > dev2bitmap("04610_080721.jpg",type="jpeg", height = 10, width = 10, res = 200) Error in dev2bitmap("04610_CSF080721.jpg", type = "jpeg", height = 10, : sorry,...

Hi, I don't know if I am the first one to report the problem: in 2.8.0 dev2bitmap gained aa support, but "extra" is null if neither taa nor naa is specified. > dev2bitmap("plot.pdf",type="pdfwrite") Error in paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=", type, : object "extra" not found > dev2bitmap("plo...

Dear all, When saving a plot with the dev2bitmap command: name <- c("test.jpeg") dev2bitmap(name,type="jpeg",height=8,width=13,res=400) Everything seems to be ok... After importing this picture in CORELDRAW (for a poster A0) format the resolution and colors are not optimal. How can I save pictures (colors/reso...

Issue: I have a R script that is invoked periodically by another process. In the script, a graphics is generated and I want to get a the image for the graph as a jpeg. Here is a prototypical version of the script (try.R): plot(1) dev2bitmap("try.jpg", type = "jpeg") I am running R-1.0.0 on Solaris 7. The script is invoked as: R --vanilla < try.R A file named try.jpg is created but it contains a blank image, not the plot created from the script. Device inserted after plot(1) tells me that the current device is...

Hy all, I wish to get rid of starting X to get graphics, i tryed dev2bitmap and i've being working around without finding good parameters. By example : Dev2bitmap(file="Rplot001.png", type = "png256",width=600/72,height=486/72) par(mar=c(5,2,1,1),xaxs = "i", yaxs = "i",ps=13) I tryed with res=something inside dev2bitmap...

Hi, I am trying to put some graphics I have generated from R on a webpage using dev2bitmap to create a bitmap, .BMP, file. When I look at my notes from 2 or 3 months ago I was successfully able to put the ACTIVE device plot result into a bitmap file using a command such as: dev2bitmap("InsectSpray.BMP") Job done! Now when I try the same command, I get the following: >...

It would be nice for checking documentation to be able to generate the "see also" cross references (e.g. the list of functions where dev2bitmap is linked as a "see also" reference.) Perhaps this already exists? (BTW, it would be useful to have a "see also" reference to dev2bitmap in the help for postscript and for Devices.)

Hi list, When exporting to PDF a graph with a legend, in the final PDF, the text is going beyond the legend box. > dev2bitmap("test.pdf", type="pdfwrite", h=6, w=6) The legend looks OK on the screen. I noticed that the size of the legend box depends on the size of the screen window, which is not the case for other graphical parts (text of the legend, title, axis text...) Any tip on how to deal with t...

Hi, I've installed several versions of R on a number of Window systems. I get the following error message (which I don't get on linux) > dev2bitmap(file="test.jpeg",type="jpeg") Error in system(paste(gsexe, "-help"), intern = TRUE, invisible = TRUE) : gswin32c.exe not found Any idea how to fix this?

I am having trouble saving graphs. Using the Aqua interface (which is not my preferred interface), I have no problems plotting a graph, adding additional lines, points, references, etc., and then saving it to a file using, for example, the dev2bitmap command. I have found that, running R with Xemacs+ESS under X11 (which I prefer over Aqua), this is not possible. I can either send the graph to a Quartz or X11 window, where I can then manipulate it using my mouse, but not save it (using dev2bitmap or postscript or any other saving command create...

Hi, Without trying to print 1000000 points (see <http:// finzi.psych.upenn.edu/R/Rhelp02a/archive/42105.html>), I often print maps for which I do not want to loose too much of coastline detail, and/or plots with 1000-5000 points (yes, some are on top of each other, but using transparency (i.e. rgb colors with alpha information) this actually comes through as useful information.

...n 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", type = "png256", height = 6, width = 6,res=72) I end up with "plot.png" as a nonzero png file, but it is always blank...

Using R-1.1.1 on RedHatLinux 6.2. I've made some progress, succeeded in outputting bitmap, jpeg, and png files. Yipee. I did them with this command: > dev2bitmap("whatever.bmp",res=300) > dev.print(png, file="myplot.png", width=480, height=480) > dev.print(jpeg, file="myplot.jpg", width=480, height=480) > dev.print(pictex, file="myplot.tex", width=480, height=480) Now here are the things I don't underst...

...option of not centring on the page. Oh, and I do know it is gswin32c on Windows: that is easy to incorporate but I have not tested it. One could attempt to retrieve height and width from the current device, but I don't see that information is presently available from R code. Any comments? dev2bitmap <- function(file, type="png256", height=6, width=6, res=72, pointsize, ...) { rc <- system("gs -help > /dev/null") if(rc != 0) stop("Sorry, gs cannot be found") gs <- system("gs -help", intern=TRUE) st <- g...

...long time ago. R seems to work fine except script-based plot saving as pdf has not worked. I have tried the following, none of which seem to function, xyz <-read.table("time_frac2") x=plot(xyz,main="imp rate", xlab="Time(GMT)",ylab="imp/minute") grid() dev2bitmap("xxx.pdf",type="pdfwrite") save.plot(x,file="xxx.pdf",format="pdf") dev.copy("pdf","auto_pdf.pdf") dev.off() savePlot("./auto_hit_rate.pdf",type="pdf") q() Now apparently R does save the plot in a default file Rplot...

Hi IU would like to modify the dev.off function, so that it automatically compresses the created pdf. I am thinking of doing the following in the modified dev.off: 1) Get the filename of the pdf device 2) close the device by calling the original dev.off() 3) compress the pdf file with a system call of pdftk. My question: how can I get the filename of the pdf from the device before it is closed?

...eally like is R's ability to quickly generate very good looking graphics. However, I've noticed that when I attempt to copy and paste the graphs from the R graphics output window into Word (in Mac OS X), the resulting picture is very jaggy. I'm aware of the various options such as dev2bitmap, but I'd really like to be able to do a quick copy and paste without switching among various applications or creating extraneous files. Thanks. -- Eric Fruits, Ph.D. Senior Economist & Project Manager ECONorthwest - Portland

...graphics windows height:width ratio is the ypinch:xpinch ratio from the call to windows. windows(10,1,xpinch=96,ypinch=192) will produce a window which is higher than wide, which is not what I expected after reading the docs. (This also is true in R 2.4.0 alpha) The alternative solution is to use dev2bitmap. windows(3,2) plot(1:10) dev2bitmap(file="test.bmp",type="bmp256",width=3,height=2,res=100) produces a bitmap of size 300x200 which is exactly what is to be expected. In this bitmap, however, the leftmost part of the image displayed in R's graphics window is cut off. What...
