Hello all, I create the following matrix: m <- matrix(1:20, nrow = 10, ncol = 2) which looks like: [,1] [,2] [1,] 1 11 [2,] 2 12 [3,] 3 13 [4,] 4 14 [5,] 5 15 [6,] 6 16 [7,] 7 17 [8,] 8 18 [9,] 9 19 [10,] 10 20 Then, I want to remove randomly 2 rows among the ones where m[,1]<8 and m[,2]>12 I suppose the

Hello, I'm running a PB G4 with Mac OS 10.4.1. I have downloaded the latest version R-2.1.0a.dmg. It appears that R does not work. It launches itself, but the window never gets ready, there is written "Loading R..." and a small progress wheel keeps turning indefinitely. Could someone help or suggest something? THANKS !!

Hi, I'm unable to find a way to smooth data for a persp() graph. Example, suppose that I have data x,y,z like this: x <- 1:10 y <- 1:10 k <- 20 z <- outer(x, y, "*") + matrix( k*runif(100, -1, 1), 10, 10) persp(x, y, z, theta = 35, phi = 25) The graph is not very nice. Is there a way to smooth the z data so that at the end the graph would look more like something

Estimada comunidad tengo un problema del que no encuentro datos que me ayuden mucho en la web. Estoy haciendo calculos por grupos con data,table. Tengo un archivo (zp.res) con tres columnas que clasifican los datos (sol, con, dia) y una columna de datos numericos (media), de la siguiente forma: sol con dia media 1: con 0 1 -22.6 2: con 0 1 -36.6 3: con 0 1 -35.6 y

Hey folks, I'm new to the R Project so I'm facing a great problem. I've read a file into R: >myVal I V L F C M A G T W S Y P H Q D N E K R 1 4,5 4,2 3,8 2,8 2,5 1,9 1,8 -0,4 -0,7 -0,9 -0,8 -1,3 -1,6 -3,2 -3,5 -3,5 -3,5 -3,5 -3,9 -4,5 > mode(myVal) [1] list Now I want to multiplicate each of this values with this one:

Hello, This code builds a simple example of 2 wireframes : require(lattice) x <- c(1:10) y <- c(1:10) g <- expand.grid(x = 1:10, y = 1:10, gr = 1:2) g$z <- c(as.vector(outer(x,y,"*")), rep(50,100)) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows = FALSE)) However, the intersection between the wireframes is not properly drawn. Is there a way to fix this

Hi list, I'm running R CMD check for a package and I would like to save the .tex file that generates later the pdf documentation. I have only seen it appearing and disappearing quickly in a tmp folder but I have not been able to save it. I could not find any option to the check command to save it. Any idea how I can save this tex file? Thanks Guillaume

Dear List, This is just a programming problem which i cannot seem to figure out. I am trying to get a set of power from a test (say, kolmogorov smirnov) out of a distribution (say, G-K distribution) as follows. I am trying to reduce to pain of writing the whole set of data points (p# below) using "for" loop. However, I seem to have some problem in it as the output "M" does not

Hello, I've got an Asterisk server with a TDM400P with 2 FXO modules and 2 FXS modules. This server is connected to 2 PSTN lines and 2 analog phones. In my Zaptel configuration, I've defined 2 groups : one for the 2 FXO's and one for the 2 FXS. The asterisk server is just used to add a little IVR and Voicemail service. Eveything works fine, but sometimes the conversation is

For my problem I have #Constraints b11<-0 b21<-0 b12<-0 b22<-0 n1>=0 n2>=0 n1<=1 n1<=1 n1+n2=1 In order to use spg I set Amat<-matrix(rbind(c(rep(0,10)),c(rep(0,10)),c(rep(0,2),1,rep(0,7)), c(rep(0,3),1,rep(0,6)),c(rep(0,10)),c(rep(0,10)), c(rep(0,6),1,rep(0,3)),c(rep(0,7),1,rep(0,2)), c(rep(0,8),1,rep(0,1)),c(rep(0,9),1,rep(0,0)),

Hi, I have a matrix not unlike this: foo <- matrix(,5,5) foo[5,1] <- 1 foo[1:3,2] <- 1 foo[3:4,3] <- 1 foo[4:5,4] <- 1 foo[2:4,5] <- 1 foo [,1] [,2] [,3] [,4] [,5] [1,] NA 1 NA NA NA [2,] NA 1 NA NA 1 [3,] NA 1 1 NA 1 [4,] NA NA 1 1 1 [5,] 1 NA NA 1 NA I want to get a vector that is the column numbers as sorted

Hi, I am trying to write a simulation of the movements of four animals between six patches. The movement between patches is based on a first-order Markov chain so that the next patch they visit depends on the patch they were in before. I have written code that allows me to simulate the movement of one animal but when I add more there seems to be a problem and all chains come back as N/A. I can

Hi, I am trying to combine a long list but I can't work out how to do it, for example: abun<-list(rep(0,5),rep(0,7),rep(0,4),rep(0,10)) nb<-c(5,5,1,8) fill.abun <- function(x, y) { set <- sample(1:length(x), size = y) x[set] <- rlnorm(length(set)) return(x) } abun <- mapply(fill.abun, abun, nb) abun ## I want all the data in one

Hi, I apologize for the long message but the problem I encountered can't be stated in a few lines. I am having some problems with the function constrOptim. My goal is to maximize the likelihood of product of K multinomials, each with four catagories under linear constraints on the parameter values. I have found that the function does not work for many data configurations. #The likelihood

I would like to randomly shuffle a distance object, such as the one created by ade4{dist.binary} below. My first attempt, using sample(jc.dist) creates a shuffled vector, losing the lower triangular structure of the distance object. How can I Ishuffle the lower triangular part of a distance matrix without losing the structure? Thanks. --Dale x1 <- c(rep(0,4),1) x2 <- c(rep(0,2),rep(1,3))

Hello Samba team ! I'am in a very delicate situation. After an upgrade to debian Stretch my DRS stopped working. I have three DCs (fichdc, fichds01, fichds02), all Debian Stretch, all with the same problem. Everything seems to be fine except DRS. -> File shares works -> DNS (with bind9 DLZ) works -> "kinit administrator" works -> "kinit -k FICHDC$" works ->
