How to run R to generate graphics (jpeg) files dynamically ?
Hello. I am getting started with R system and I have a question: I'd like to use R system to generate some graphics (jpeg) files dynamically from command line or perl script (like: > Rgui -input_r_file <file>.r -output_jpeg_file <file>.jpeg) 1) How should I invoke R to read the data from external file. 2) How should I invoke R to run statements from external *.r file. 3) How

Ctrl-C with R.exe and Rterm.exe in R v1.9.0
Hi, I'm running R v1.9.0 on WinXP Pro. I noticed that R.exe and Rterm.exe behave differently on Ctrl-C. Starting a Windows Command prompt (cmd.exe) you get from running Rterm.exe: C:\Program Files\R>rw1090\bin\Rterm.exe --vanilla --quiet > ^C > ^C > 1+1 [1] 2 > Sys.sleep(100) # Ctrl-C after a few seconds > ^C > ^C > 1+1 [1] 2 > q() C:\Program Files\R>

install bug with specific JPEG library by exporting CPPFLAGS variable
Hi there, I think I have found a small problem in the "/my/path/R-2.0.1/src/modules/X11/MakeFile" generation. During the configure step, I have specified a specific JPEG library by exporting CPPFLAGS variable. All compilation works well for individual files in the src/modules/X11/ directory, but when linking, the -ljpeg option doesn't work. I obtain the following message (in french

Moving Rterm.exe to another location
Colleagues, I have encountered the following situation in R (2.9.0) with Windows XP. I have an application that calls Rterm.exe. In certain situations, the application terminates but fails to close R. Then, the next time that the application runs, there are replicated copies of R running - this slows the system. One solution would be to kill any open versions of Rterm.exe each time

Rcmd vs. Rterm.exe
Hi r-hackers, What exactly is the difference in call r from a batch between this two ways: Rterm.exe ... Rcmd BATCH ... (I have to install perl first, I know) I haven't found any documentation about the difference (readme, FAQs, ...). I use rterm.exe, but is there a benefit in using rcmd? Can you explain me that or give me a link? Thanks Thomas Thomas Untern?hrer

rterm.exe and graphics windows
I have started using R 1.5.0 on Windows 2000. The refinement of this system in such a short time is astounding, and I thank those who have worked on it and made it available! I have been using rterm.exe to develop R scripts in my preferred editor (not emacs) by sending the command rterm.exe --save < %f where the editor substitutes the filename for %f. This works wonderfully, and the

Rterm.exe, windows event loop running in multiple threads?
For processing events, RGtk2 has moved away from using the old tcl_do hack and now synchronizes on the Windows event loop. In Rgui.exe this works fine (well mostly), but in Rterm.exe, users report the following warning from GLib: "main loop already active in another thread". The most obvious way this could occur is if the Windows event loop were iterating in multiple threads. This does

Rterm.exe stops responding to keyboard input
I've been trying to use Rterm.exe, mainly because of Rgui.exe's lack of support for incremental history searching. But on my system (Win XP, SP3), it (rterm from R-2.8.1) frequently just stops responding to keyboard input. This happens often (enough to make it unusable), and generally after a switch to another window. It doesn't seem to hang exactly, as if I leave it a while (minutes)

Problem with .libPaths & Rterm.exe (under Vista)
Dear list, I?m using R embedded in another program (coded in tcl/tk) under Windows Vista. In this context I don?t launch Rgui.exe but rather Rtem.exe. Now I have a problem finding libraries not specifically installed as administrator (and which are not in the path ?program files? but in Contacts\Documents of the current user). To be precise, the user launching my tcl/tk program can?t find

readJPEG function cannot open jpeg files
I installed jpeg package and tried to use kim<-readJPEG("kim.jpeg") to read in a jpeg file, but R gave me an error: Error in readJPEG("kim.jpeg") : unable to open kim.jpeg I already put "kim.jpeg" in Rstudio's default working directory: "E:\home work\Rstudio". So I don't think it's a problem caused by omitting the file's path. But I

jpeg in batch mode
Hello, I am running some commands in batch on a server that I SSH into; some of the commands call jpeg(). If I continue to stay signed on (with my xwindows working on my machine) then the jpeg() command works (with a single caveat, below). If I leave it and sign off (with a nohup command in front of my BATCH) then jpeg gives me an error like this: Error in X11(paste("jpeg::",

print to .jpeg
Evening folks, I'm trying to print a series of graphs to .jpeg using a variable as the title, but run into the difficultly that I can't find a way to append the file extension to the .jpeg (in this case extensionless!) files. Example: ---- species.name="CussoniaHolstii" dia<-10:100 biomass = -21.4863 + 0.5797 * (dia ^ 2) biomass jpeg(species.name) plot (biomass,

saving graphics in jpeg format
Dear R users, I need to save a graph in jpeg format. After plotting the graph, when the graphics window is active, in the File menu, the Save as / Jpeg / 100% quality correctly saves the graph in jpeg format. But I would like to know, how could I control the resolution (in dpi) of the saved jpeg file? I need to produce a jpeg at 1200 dpi. I have tried also the jpeg function in the package

density and jpeg
Dear R community, I am using densityplot (lattice package) for a large dataset and wish to print it to a jpeg (the pdf is huge). R crashes consistently. Am I doing it wrong or is densityplot incompatible with jpeg?

Failure to produce italics in jpeg
Colleagues, Using R 2.10.1 in OS X (Snow Leopard), I created JPEG documents that were intended to include italicized text. In the JPEG versions, the italics appear in bold-face. The identical code (except for the call to the device) yields italics in PDF. A minimal example is: PDF version: > pdf("plot.pdf") > plot(1,1) > mtext(bquote(italic(P) < .(0.005))) >
