Hello I have 4 1000*1000 matrix A,B,C,D. I want to use the corresponding element of the 4 matrices. Using the "for loop" as follow: E<-o for (i in 1:1000) {for (j in 1:1000) { E<-fisher.test(matrix(c(A[i][j],B[i][j],C[i][j],D[i][j]),2))#call fisher.test for every element } } It is so time-consuming Need vectorization Yours sincerely ZhaoXing Department of

Hi, I am working with R version 2.1.0, and I seem to have run into what looks like a bug. I get the same error message when I run R on Windows as well as when I run it on Linux. When I call anova to do a LR test from inside a function, I get an error. The same call works outside of a function. It appears to not find the right environment when called from inside a function. I have provided

A general question that I have been pursuing for some time but have set aside. When finishing some analysis, I can have multiple matrices that have specific column names. Ideally, I would like to combine these separate matrices for a final output as a csv file. A generic example: Matrix 1 var1A var1B var1C x x x x x

Hey all, I can't for the life of me figure out what I'm missing here. I'm trying to change the color of the line in a time series type plot. I can change the point colors and symbols no problem, but for some reason the colors do not get passed to the lines, regardless of if I do type="b" or type="l". The sample code I'm using is below. Any help would be

hi Using a ts or tprs basis, I expected gcv to decrease when increasing the basis dimension, as I thought this would minimise gcv over a larger subspace. But gcv increased. Here's an example. thanks for any comments. greg #simulate some data set.seed(0) x1<-runif(500) x2<-rnorm(500) x3<-rpois(500,3) d<-runif(500) linp<--1+x1+0.5*x2+0.3*exp(-2*d)*sin(10*d)*x3

Buen Día Jorge, Es algo parecido a lo que necesito, pero no debo tener en cuenta la suma de la columna sino por ejemplo: Tengo el elemento [1,2] en la matriz A que contiene el número 5 y por otra parte tengo la columna [,2] de la Matriz B con valores por ejemplo (1,2,3,4,5,6,7,8,9,10,11,12). El resultado debería ser un vector que en la posición uno debe indicar que existen 7 valores mayores a 5

Hello, I am new to R and need some help with the legend. How can I add a legend for two variables (in two columns) each having multiple values to be explained in the legend. For example: Var 1 Var 2 <symbol> - Higher <symbol> - Higher <symbol> - Avg <symbol> - Avg <symbol> - Lower <symbol> - Lower I know we

Hi R, I have a matrix, > x1=matrix(NA,6,6,dimnames=list(letters[1:6],LETTERS[1:6])) > x1 A B C D E F a NA NA NA NA NA NA b NA NA NA NA NA NA c NA NA NA NA NA NA d NA NA NA NA NA NA e NA NA NA NA NA NA f NA NA NA NA NA NA > x2=matrix(rpois(9,1),3,3,dimnames=list(c("b","a","f"),c("D","E","F"))) > x2

Buen día amigos, Antes que nada, reitero mis agradecimientos por sus respuestas tan precisas y oportunas, sigo en mi trabajo de grado y tengo dificultad con un proceso: Tengo dos matrices A y B, A es de dimensión 5x4 y B es de dimensión 274x3. Requiero de un proceso en el que tome el primer elemento de la Matriz A columna 2 y lo compare con todos los elementos de la Matriz B columna 1 y me diga

Dear List, The following code produces a list, which is what I what: set.seed(123) tmpf <- function() { x <- rpois(rpois(1,4),2) } n <- 3 m <- replicate(n,tmpf()) m [[1]] [1] 3 2 4 [[2]] [1] 0 2 4 2 2 5 2 [[3]] [1] 2 0 4 1 0 Now I need something that would to extract iteratively (or as many times as the size of 'n') the values that are greater than 2 in each component of

Hi all, I have configured HTB classes on my public interface. I have split the bandwidth among two subclasses say 1:2 and 1:3. Lets say if I configure the rate limit of say 1:2 as 250kbps with a ceil setting of 1000kbps, I presume it means that the class can have bandwidth upto 1000kbps, provided the bandwidth is unused, if not it is assured a bandwidth of 250kbps. Is my understanding

m1 <- matrix(rnorm(40), ncol=4) m2 <- matrix(rnorm(40), ncol=4) I would like to subtract first column of m1 from all columns of m2, subtract 2nd of m1 from all columns of m2, and so on. Obviously, I am not using the appropriate function outer(m1, m1, "-"), since the first column isn't all 0s. _________________________________________________________________
