I am considering a package with a namespace (Rgraphviz from Bioc). I essentially want to have some error handling for loading the dll, something like wrapping it into tryCatch or similar (reason: see below). Right now I am loading the dynamic libraries by useDynLib in my NAMESPACE file. When I look at the code from loadNamespace, I have the impression that what I want is impossible

I'm writing a package that interfaces to the FAME database, via a library of compiled C routines accessible through a Linux .so file. My .onLoad() function loads the .so like this: dyn.load("/opt/fame/timeiq/lib/linux_x86/libjchli.so", local = F) and after that I also load my own fame.so via library.dynam("fame", package = "fame") The code in fame.so uses

Hello, I am a student and I working with R. I want to ask you how to solve this integral which is shown in image attach with this letter. And how to draw this function z = 4 ? x2 ? y2 , width intervals x = ?1, y = ?1. Thank You. Yours sincerely, Jolanta

Hi R-People: I use 2 machines: a machine with a Windows XP operating system, and another with a Linux Ubuntu OS. I transport my code between these 2 machines. However, pathnames to data files always need to be "adjusted" to account for the OS that I'm working on. Here is my question: How do I write code to detect whether I'm using the XP or the Linux machine? If I knew

Dear All, I wonder whether anyone has an experience with FAME package written by Jeff Hallman. All my attempts to send him the following problem report did not succeed (the mail system says that my e-mail could not be delivered), so I turn for help to this list. I tried to use your FAME package written for R, but somehow I cannot get it working. I am using Windows XP and the newest R

My fame package has a function that checks to see if a FAME SERVER process is already running. On Linux, I can do this in one of two ways: pid <- Sys.getpid() user <- Sys.info()["user"] cmd <- paste("pgrep -fU", user, "-P", pid, "'FAME SERVER'") fameRunning <- as.logical(length(system(cmd, intern = T))) or I can use cmd

My fame package has to link to the libchli.so that comes with FAME. However, FAME is now supplying both 32 and 64 bit versions of the library. The 32-bit version is $FAME/hli/libchli.so while the 64-bit version is $FAME/hli/64/libchli.so. To set the right flags, it seems that I need to know, from within configure.ac, whether the R installation is 32 bit or 64 bit. Is there a way to detect this?

One hassle I could do without is the necessity of writing C wrapper functions like this: void fameInit(int *status){ cfmini(status); return; } when I want to call a library function (cfmini, in this case) that takes an int argument. The .C interface only lets me pass a pointer to an int, rather than the int itself. Is there any chanch that .C could be enhanced to allow passing arguments by

Hello list member: I've recently had a problem in that I'm unable to quit an R Session. I noticed this after the update to 2.8.0, but I believe I also noticed it on another machine, in the previous version. It occurs on both linux and Mac platforms. It only occurs when I start R in some particular workspaces that have alot of objects in them; it does not occur if I start R in an

I have found several instances where rsync refuses to copy a new file. I am using it to sync changes from a staging web server to production servers, and there are certain files that it just plain won't copy. The file is totally new. No such name has ever existed on the target server(, or on the source server until now). In this instance, I added 3 completely new files to the same

Hello, helpeRs, I've been trying, unsuccessfully, to change a dataframe from long to wide format using reshape (the original). I would appreciate it if someone could demonstrate the correct syntax. The script below will create a toy example. The new wide data should have a column name for each unique entry in the "fame" column. Under each column should be either the

I am trying to move our network from windows NT-2k to Samba /Linux. So far everything is great but there is one main obstacle; when I apply permissions to a Samba share via my W2K workstation, the permissions instantly disappear. This happens regardless of the owner / creator of file or the user / group permission I attempt to add. I have run 2.2.7, 2.2.8, and now 3.0 beta3. All three behave

Does anyone have information or know how I can find out what option this rpm was built with? ie with winbind on... I still seem to be having odd winbind / samba / acl problems (cannot get perms. modified via a Win2k station to stick). Regards, Matt Twigg

We have upgraded from Samba 2.2.7a to 2.2.8a. We have samba running our our two UNIX file servers, one is Solaris 8 and the other RedHat Linux 7.3. Samba was compiled as follows: configure --prefix=/opt/samba --with-acl-support --with-quotas Right now it doesn't looks like changing file/folder permissions are working from W2K. When we right click on a file/folder and go to the

Hello, We as an organization are going to use SFTP for our data transfer. Our requirement is to SFTP the file from IBM Mainframe (z/390) to Unix or Windows. Currently we are using FTP, which converts the character set from EBCIDIC to ASCII and also take care of CR and LF aspect. My question is, do the same feature is available in SFTP, where it smartly understand the source and destination

Can anyone please advise me what is involved in up grading a project from version 1.2.6 to current (2.3.5). The project is pretty much vanilla code and does not use plugins. Are there scripts that can do the job (or pull out incompatibilities). Any websites or blogs that point the way or should I just bite the bullet and rewrite? Reason for wanting to upgrade is that I now do want to add features
