Hi, all. I began to migrate my R codes from Windows to Linux and surprised me with an old question. I simplified the problem and made a little test to compare times at same computer and the Linux time is worse (not so little) than Windows time: 28 vs 53 seconds. I make an example (below) to facilitate all to see the difference. I also build from source (it's my first time) a version of R to

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'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)?

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'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. 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

Hello. I am still a newbie in R. Excuse me if I am asking something obvious. My efforts to get an answer through browsing the mailing archives failed. I want to perform an augmented Dickey-Fuller test and to obtain AIC and BIC and to be able to impose some linear restrictions on the ADF regression so as to decide the correct order of autoregression. However I could find no obvious way to impose

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, 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.

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

Hello everybody, I?m using Red Hat 7.3 with Samba setup as a PDC, and I?m having a doubt. I am studying the directive "obey pam restrictions" because I would like to limit the number of logins with the same id. The documentation provided by SWAT tells me that encrypted passwords (like used by Windows98SE) will NOT follow these restrictions. Anybody could tell me if this information is

Hi folks, Maybe that is not the best place to ask, but I 'd like some of you could help me... I'm using jri to run R commands under Java, by its examples I can eval expressions, returning single values or vectors to my Java variables. But, I would like to know how to assign the values of a Java vector (like: double x[] = {1.7 , 2.8 , 3.4}; ) to a R variable, so I can eval a function
