Hi. I searched the list and didn't found nothing similar to this. I simplified my example like below: #I need calculate correlation (for example) between 2 columns classified by a third one at a data.frame, like below: #number of rows nr = 10 #the third column is to enforce that I need correlation on two variables only dataf =

Hi, all. I didn't find something similar to this problem in past list. I have a data frame (named restr) where some columns are factors, like you can see: > table(restr[,"p1"]) 0 1 2 3 4 5 0 26 1 0 1 0 > table(restr[,"p2"]) 0 1 2 3 4 5 6 0 13 11 1 2 1 0 When I use apply, the factor structure is missed: >

Hi, all. I searched a lot at mailing list, installed EBImage and gtk packages, but I couldn't make this simple work: How to add a image file (jpg or bmp ou gif) to an existing plot window (not plot over the image), like the code below (pseudo function add.image): plot(1:10,1:10,main="test") image = read.X("myimage.jpg") add.image(image, x.left=2, y.bottom=4,

Hi, all. I'd like to know if exists a manner to get the first index where a condition is attained in a vector. For example, There is a better solution than first.index <- table(subject[corretor==27])[1] (give me the subject for the first time that corretor is 27)?

I have a 2 node cluster of HP DL380G4s. These machines are attached via scsi to an external HP disk enclosure. They run 32bit RH AS 4.0 and OCFS 1.2.4, the latest release. They were upgraded from 1.2.3 only a few days after 1.2.4 was released. I had reported on the mailing list that my developers were happy, and things seemed faster. However, twice in that time, the cluster has gone down due

Hi, Does OCFS require NAS hardware to run or does normal PC hard disk work? Thanks, Pete -------------- next part -------------- An HTML attachment was scrubbed... URL: http://oss.oracle.com/pipermail/ocfs2-users/attachments/20081219/1bc9110b/attachment.html

Ok fellows, This is my last try. Please, anybody tell me if something is missing on this list! I need to setup on a Linux + Samba (PDC) to restrict just one login per ID (not allow two logins with same id).So: 1 - edit /etc/pam.d/samba -> chaging session line with session required /lib/security/pam_limits.so 2 - in /etc/security/limits.conf: * - maxlogins 1 3 - in smb.conf:

Hi, all. Suppose I have an object with names (like a data.frame) and I want to walk in a loop with your names. How can I do this? The idea is like this: my.data<-data.frame(matrix(runif(6),ncol=2)) names(my.data) [1] "X1" "X2" for(i in names(my.data)){ my.variable <- cat(paste("my.data$", i, "\n", sep="")) print(mean(my.variable)) } #it

Hi, I have a particular situation that syslinux could access a i2c bus to get some data from specific device that my hardware has. Based on these data, syslinux should or not to boot. It's feasible to create some i2c infraestructure to syslinux access i2c bus? It could be used to something more than only my needs? I digged in gpxe code and it has code to provide some i2c functionality.

Why not use linux as bootloader? Booting a (rather small) linux kernel with I?C support and either shutting down or kexecing another linux kernel (plus

Hi all. I'm working with a short plot (3x3 inches), but the results (via postscript command) are not nice. The lwd command don't affect the lines (that are very large) and the margins don't change using oma, mai, mar, ... Below I put an example. Moreover, save the graphics via postscript command isn't working well (see the attached ps). Thanks by the help, Cezar Freitas.

Hi All, I'm trying to build klibc against my own kernel source tree. The build goes fine, the problem is to install it. As usr/klibc/README asks, I've create a symlink called linux pointing to my kernel tree: lrwxrwxrwx 1 root root 25 Jul 2 16:18 linux -> /usr/src/linux-2.6.22-rc6 anderson-herzer:/usr/local/src/klibc-1.5# export LANG=C anderson-herzer:/usr/local/src/klibc-1.5#

Dear all, I intend to do some statistics with my raster table, like correlations or regression analysis. For that, I need that each pixel be in one line, that is, there is no count > 1. So, all columns should have the same number of lines, when I compare (combine) rasters. I'd like to know if there is a way to create lines and copy the values of the lines, when count is > 1. So, even

I've been using OCFS2 on a 3 way Centos 5.2 Xen cluster for a while now using it to share the VM disk images. In this way I can have live and transparent VM migration. I'd been having intermittent (every 2-3 weeks) incidents where a server would self fence. After configuring netconsole I managed to see that the fencing was due to a heartbeat threshold timeout so I have now increased

Hi, I have some files in mp3 in my Asterisk but when I play it the volume is lo= wer than wav files. Both the files (wav and mp3) are encoded with the same = amplitude. In anothers players the audio volume of these files are equal. Can I fix this diference between volume of mp3 and wav file?
