Dear useRs, Do you know, by any chance, if it is possible to write a string in the header/footer of a pdf file created during a plot session? To make sure that I know what R script generated a certain chart, I would like to add the path to the working directory into the header/footer of the corresponding pdf file. Thank you.

Dear useRs: Please provide me with your thoughts on an issue related to the design of a production level system. For example, let?s suppose that I need to run the same R script for a finite sequence of items (e.g., in the energy industry, I may need to asses the profitability of all gas stations in the state of Florida). For each of the items, the R script accesses some remote databases, gets

Dear useRs, I would like to query an Access database through R based on a date attribute but, unfortunately, I fail to do so. For example, the table test_table of the test.mdb looks like: ID cd market competitor dd price 1 1 2007-11-20 atl-bos delta 2007-11-20 210 2 2 2007-11-20 atl-bos delta 2007-11-21 190 3 3 2007-11-20 atl-bos delta 2007-11-22

It seems that Access needs that you surround the dates with a # symbol. You probably need something like. res <- sqlQuery(channel, "select * from test_table where market = 'atl-bos' and competitor = 'delta' and dd = #2007-11-20#") Hope this helps, Stefano -----Messaggio originale----- Da: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org]Per

Dear UseRs: I intend to write a package to handle the basic operations a revenue management analyst has to deal with on a regular basis (e.g., demand untruncation, capacity allocation, pricing decisions, etc.). Following the directions posted by Peter Rossi (Making R Packages under Windows: A Tutorial, January 2006) I was able to build an interim package that currently consists of one simple

Dear R users: Is there a way to append selectively to components of a list (if possible, loops are to be avoided)? To illustrate the point, in the example below, I would like to append 99 to vector b of the list l. > l <- list(a=c(1), b=c(2,3), c=c(4,5,6)) > l $a [1] 1 $b [1] 2 3 $c [1] 4 5 6 As you may expect, the result should look like: > l $a [1] 1 $b [1] 2 3 99 $c [1] 4 5

I'm loading a program from CD-ROM .. the splash screen comes up, but then a dialog box comes up with "Failed to initialize ..." btw, I'm running wine under the 2.2.16 linux kernel and the partition I'm running this program from is a win2k ntfs partition (the program is not limited to win2k however.. just what i have) Here are some of the errors (randomly selected) that

Hi; We've recently upgraded from Samba 1.7 to Samba 2.2.8 and we're using Samba to allow our users to connect to their Unix home directories from their PC's. Under 1.7 users were able to connect by mapping a drive from windows explorer and entering their unix username and password. Now, when we do this we get a "Incorrect password or Unknown username" error message.

I am trying a "netstat | grep netbios" and receive nothing back. I tried "netstat | grep 139" and nothing as well. I have the correct netbios ports in /etc/services. Does anyone know to make this show up with a netstat or have those services running? I believe this may be my problem with the mapping of samba shares to the client. Any help would be appreciated, Dan

Hi! I'm trying to install centos 5.1 as a http installation from a centos mirror. i've done it before with Fedora, figured I could do it with Centos, too, but every time I try it, it goes all the way thru Anaconda to the point of entering the root password, then I get an error about not being able to find the repodata. I note that the section in the "upstream" manuals about

I was trying to patch Xen 3.2 from the mercurial repository with the MSI patches by Yunhong Jiang given at the bottom of this page : http://lists.xensource.com/archives/html/xen-devel/2007-11/msg00157.html The tree seems to have significantly changed, especially the hvm_irq_dpci_mapping structure in irq.h header file. Are there any updated patches, or can I get a version of Xen from somewhere

Hi Folks, I want to calculate latency in transferring a buffer from domU kernel to dom0 kernel and vice versa. for that I need a time ''flavour'' (cycle counter time?) which reads the same in dom0 and domU. Could someone please let me know if cycle counter time is the right time to use? if not then which one (system time or wall clock time)? Also could someone please tell me how to

Hi all, Can anybody tell me how to generate a mov instruction in llvm. I found out there is a MemMove Inst but I dont think that is what I want. I want to bypass a load instruction. So i need to generate a mov instruction which will help me remove the redundant load. Thanks -- Abhinav Karhu MS Computer Science Georgia Institute of Technology

How is it possible to set for a file that a user can read,write but not delete it ? I'm using a xfs filesystem and samba3.0.4 with ACL's support included. -- Xavier mailto: x.poirier@free.fr

Hello, I am new to Xen and I have class project to develop in Virtualization course. One of these projects in about nVidia CUDA Virtualization. As far as I understand from the architecuture of Xen, for virtualizing CUDA on Xen, I will have to prepare a back-end (for Dom 0) and front-end (for Dom U) drivers for CUDA. Is this right? Also, from where can we get the source code of latest nVidia

Dear Members, I am trying to fit a variogram model using fit.variogram function from the gstat package. The figure showing my experimental variogram can be seen here: https://i.stack.imgur.com/UZXw4.png My code line for this operation is: > c2.vgm.fit<-fit.variogram(c2.vgm.exp,vgm(nugget=0, psill=400,model="Exp",range =40000),fit.method = 7) The system throws following error

I'm running samba 3.0.13 on a debian box, sharing out NFS filesystems from a solaris box. I know, bad idea.. file locking, etc... non-issues at the moment. I've discovered that if I make a share from a local filesystem, the PC's mounting the share see their quota (hard limit, not soft which is another matter) as their capacity and their appropriate free space... this is good.

Hi friends I just started using wine on my Linux-machine. Mostly because I want to switch finally from Windows to Linux on my computer at work. There is just one single application I want to "take with me" and that is "GraphPad Prism" (http://www.graphpad.com/prism/Prism.htm). So I installed wine0.9.20 on my Mandriva2007. Then I used wine to install Prism in its most recent
