Hi to all, So I'm also a new user. I downloaded the program last week and I think it's great. Thanks to those who have developed R. I have a special interest in GLM as a tool to describe fisheries and its variables and I'm just begging to study it. As I could understand there's two types of GLM sun of squares: in "type I" the factors are added in sequence and

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)?

Two questions: 1. inverse.gaussian is up there as one of the glm families, but do people ever use it? There is no inverse.gaussian in the R distribution family, and when I checked McCullagh & Nelder, it only appeared twice in the book (according to subject index), once in the table on p. 30 and once on p. 38 in a passing sentence. Is there a good reference on this distribution? 2. When I

Reposting from virt-tools mailing list: Hi! I'm facing a problem that could be triggered by some lacking of support from libvirt on Open vSwitch (or could be my mistake). I have interests in researching on virtual networks and SDN. To keep things simple, I've decided to use libvirt/virt-tools to manage VM's since my focus is on the network, instead of using a full feature system

Hi, I'm having difficulties in the manipulation of the function table. Necessary to have access its elements and I am not obtaining. For example, if I have a data.frame with name "df" and make: t < - data.frame(table(df)) and later trying to make a comparison of the type t[1,1 ] < 0.1, generates an error of the type: [1] NA Warning message: "<" not meaningful for

I'm using the parameters "mfrow" and "mfg" to display some graphics(plots) at the same time. Although, because of the parameter "mfg", the parameter "bg" don´t change the background color. What can I do to solve this? Here is the code I'm using... ... i <- 1 for(j in 1:4){ for(k in 1:2){ limiares <-

I have just upgraded from Red Hat Linux 5.2 to version 6.0 (with GNOME) on an intel box. I have also upgraded to the latest R version (0.64.1-2 rpm) and have also installed the corresponding GNOME rpm. However, I am not able to start R: [cribari at edgeworth install]$ R /usr/lib/R/bin/R.binary: error in loading shared libraries: /usr/lib/R/bin/R.binary: undefined symbol: __setfpucw [cribari at

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

There exists a plot 3d functions (or similar) in R?

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

When I try to install the R RPM under Mandrake Linux 7.1 (intel), I get the following error: [root at edgeworth programs]# rpm -ivh R-base-1.1.1-1.i386.rpm error: failed dependencies: libreadline.so.3 is needed by R-base-1.1.1-1 [root at edgeworth programs]# I do have realine installed: [root at edgeworth programs]# rpm -qa | grep readline readline-4.1-4mdk and

Hi, I'm using the library cluster to cluster a set of figures (method CLARA). Somebody that it work with clustering would know informs what I make to evaluate the clustering?

Hi! I have a matrix defined on geographical positions (through) row and column names. I need to change a number of elements in this matrix using the information of a data.frame containing geographical positions and a number of variables. Changing the value of one specific element is easy, but changing on a number of selected positions seems more difficult. When I use the geographical

Hello, I'm applying an arithmetical function the color (R,G,B) of each pixel of a figure and it's very slow. This is common? Other thing, are there some library to make modification in figures, eg, to alter size? If not, somebody knows some software that makes this, or either, to resize figures automatically, therefore I go to need to apply to a bank. Tks, Francisco.

Hi, I have a financial (zoo) time series with prices and volumes (although I can get the coredata as a matrix). Due to the data-source some indices have multiple observations. I want to aggregate these according to a weighted average. 11:00:01 34 1000 11:00:01 35 500 11:00:01 35 1000 11:00:02 34 500 11:00:02 35 500 should become 11:00:01 34.6 2500 11:00:02 34.5 1000 I currently do this

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. 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 =
