Hi All, I am new in R and trying to simulate random normal 2D field with mean trend say north-south. My domain is 10x10 grid and I am trying to use mvnorm but do not know how to specify the domain and the mean field. I would appreciate any help.

Dear r-help, I have a matrix, suppose, 10x10, and I need the matrix 5x5, having in each cell a mean value of the cells from the initial matrix. Please, point me to a function in R, which can help me doing that. Digging the documentation and mail archives didn't give me a result. Thank you. --- Best regards, Vladimir...

Dear all, I'm a bit confused about the output from functions that generates random values, e.g. rpois. I'm using 0.65.1 on Digital UNIX alphaev6. If I say > rpois(10,5) output is not unexpectedly: [1] 4 6 5 7 6 5 2 2 5 3 but I figured that if I go: > rpois(10,1:10) I would get a 10x10 matrix as output, with random values for each of the vector elements in the row vectors, but I'm getting [1] 3 4 3 4 6 9 10 6 11 9 so, that is obviously not the case... :-) BTW, what am I getting...? So, I went on to thinking that > outer(10, 1:10, rpois) would do the trick, but...

Dear all, I am finding difficulty in the following, I would like to create an empty matrix e.g. 10x10 of 0s and sequentially fill this matrix with randomly placed a 1s until it is saturated. Producing 100 matrices of sequentially increasing density., This process needs to be randomized 1000 times., I assume i should run this along the following lines, 1) Create 1000 matrices all zeros, 2) add a...

Hello I would appreciate your help on the followig. I want to generate random binary matrices but I need to discard those with all-1 rows. That is, for a 10x10 matrix with five 1's [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] 0 0 0 0 0 0 0 0 0 1 [2,] 0 0 0 0 0 0 1 0 0 0 [3,] 0 0 0 0 0 0 1 0 0 0 [4,] 0 0 0 0 0 0 0 0...

Hi all, I am playing around with latin squares, and wrote a recursive function that searches for valid combinations. Apart from the fact that there are very many, I run into troubles beginning with size 10x10 because the recursion depth becomes too large (max of 10x9-1=89 in this case). Why is this a problem? Isn't there enough space allocated to the stack? Can this be increased? The memory demand shouldn't be terrible, with only minimal local variables (only set and the function params r,c,...

hi I have a matrix (10x10) and I have to perform t tests on each row by considering first 5 elements as data set A and next 5 as data set B. This part is easy, However after one t test on each row, I have to randomly permute each column to get new values for each row and then perform another t.test. I can permute the column...

Hi Could somebody please explain the following to me: If x is a 10x10 matrix, typing x[3] prints all 10 values of column 3, although the length of the vector =1. Why? x[,3] and x[[3]] both give all 10 values of column 3, length=10. What is the difference between these two, actually?

...uce a 30x30 lattice grid. The 30 variables naturally fall into three groups of ten and I would like to add thicker axis lines around these to highlight this. However, I can only do this separately, so far, and I don't know how to superimpose the grid with the thicker lines (separating the 10x10 groups) onto the overall grid of all 30x30 plots. I enclose a reproducible example: ##### require(lattice) temp.df <- sapply(1:30, function(i) rnorm(20, 0,1)) splom(~temp.df, aspect="fill", varnames=paste("coord", 1:30, sep=""), xlab="", pscales=0, va...

This is my syntax: for(i in 1:length(s)) for(j in 1:length(d)) m<-d[[j]][j]/s[[i]] #m is the matrix of dimensions set to X(e.g. 10X10) However, it seems I only get one result when i get m, which is the last value of d/j, which is m[1]=0.04 in this case. I am sure Im doing something wrong here, but can't quite find the solution. Thanks. Mark

...a 1,000x1,000 box is too much to handle. I have been running the following function for over 24 hours straight on a decent computer and it has not stopped yet: clust <- rMatClust(1, 50, 5, win=owin(c(0,1000),c(0,1000))) Clearly, I need to rethink my strategy. Could I generate the points in a 10x10 box with a radius of .5 and then multiply out the resulting point coordinates by 100? Is there another package that might meet my needs better than spatstat for easy cluster generation? Any suggestions are appreciated. All the best, Jason Simms -- Jason L.

Buenas, Quiero ver si he paralelizado correctamente el proceso. Tengo dos dataframes, A y B y quiero calcular la distancia euclídea de todas las filas de A sobre todas las filas de B. Para ello he hecho lo siguiente #cargo las librerias library(foreach) library(doParallel) #establezco el numero de clusters, en mi caso 4, ya que el procesador tiene 4 nucleos cl<-makeCluster(4)

Dear R-devel: I could use some advice about matrix calculations and steps that might make for faster computation of generalized inverses. It appears in some projects there is a bottleneck at the use of svd in calculation of generalized inverses. Here's some Rprof output I need to understand. > summaryRprof("Amelia.out") $by.self self.time self.pct

I have used smooth.ppp in spatstat to create a smoothed surface plot based on randomly selected depths across a lake (as marks). I wonder if based on the smoothed surface plot if I can calculate the average depth for each 10x10 grid square across the lake. I can't see any obvious way of doing this and would appreciate some pointers. Many thanks, Graham [[alternative HTML version deleted]]
