Hi all, Aslak brought up a good point with regards to returning the pid for a popen4() method. As it stands now, it returns the pid of the shell rather than the pid of the process itself. However, my attempts to remove the COMSPEC stuff result in CreateProcess() failing with an error code of 2, i.e. "the system cannot find the file specified" - not too helpful. This is when I tried to run the "ver" command. (A short while later) Hmm...it looks like some of these command line apps are actually dll files...

...ll. The 'shell' command tries to determine which shell the user prefers via the following steps: shell <- Sys.getenv("R_SHELL") if (!nchar(shell)) shell <- Sys.getenv("SHELL") if (!nchar(shell)) shell <- Sys.getenv("COMSPEC") For me, shell evaluates to "c:/cygwin/bin/bash.exe" . The 'shell' command then tries to determine the proper flag to use: if (missing(flag) && any(!is.na(match(c("bash", "tcsh"), shell)))) flag <- "-c" For anyone who is...

All, I've encountered the same problem as others who have posted under the same subject. I've had R-1.8.1 installed and running since it was released. Yesterday morning when I tried to start Rgui.exe I got the subject error message. Since I live at the whim of the network administrators I can only assume it was a recent MS critical update. I tried installing R-1.9.0 but no joy. I

...ince discovered that when GSAK tries to execute BABEL.BAT (GSAK is a delphi program which uses something similar to VBs ShellExecute to run batch files), wine looks for cmd.exe to run and fails to find it. I tried to correct this by linking cmd.exe to wcmd.exe to execute, because I figured setting COMSPEC wouldn't be enough as GSAK is looking for cmd.exe not wcmd.exe, with the following results: wine: could not load L"C:\\windows\\cmd.exe": Module not found I then tried a few other .exe files in the windows directory under wcmd, such as winhlp32.exe, and I produced similar results....

Dear all, I seem to be unable to check a source package since I upgraded R to 2.3.0 (Ubuntu Linux 5.1). I get this: * checking package dependencies ... ERROR > tools:::.check_package_depends("/home/adi/Work/QCAGUI") I have even tried with R-patched, same result. My Renviron does specify the path to the installed packages (and all depending packages are installed):

Can somebody confirm some unexpected behavior? This is under Windows, with R 2.11.0 and 2.11.1. 1. Create a trivial test file (I called it test.R) containing: cat("Success.\n") 2. Load R (Gui or Term) and run: shell("\"C:\\path\\to\\Rscript.exe\" \"C:\\path\\to\\test.R\"") In my case, I get various error messages. If the path\\to\\Rscript.exe has spaces

I installed R project 1.9.0 on Windows XP. The installation went well. Then, I rebooted. Next, I clicked the icon under Programs in the Start menu and received this error, "Fatal Error: Invalid HOMEDRIVE". I clicked OK to the error message. The program does not start. I went to a DOS prompt and did "echo %HOMEDRIVE%" and it returned "C:". This letter is a valid

Hi, I was wondering if anyone is aware of an R interface to ImageMagick (www.imagemagick.org)? Since R does not support a lot of image processing functions, having such an interface could be very useful. Alternatively, ImageMagick has a couple of different interfaces (including to C and C++). I was wondering if one can use these to call ImageMagick functions from R. I am posting a similar

...but I cannot figure out how to specify the other registers... Also, I need to find a way to be able to: unhook int 13h and int 15h and put them back to the BIOS vectors, and yes, I know some DOSses rehook int 13 - but it can be done.. I need to be able to boot a CD, load the ElTorito driver, put comspec to the CD, and remove the image from memory.... I was going to write a small dos program to do that - but I don't know how to detect that MEMLINUX is present... -Maurice
