I would use replicate() to do an operation with random numbers repeatedly: ``` mysim <- replicate(10, { two.mat <- matrix(rnorm(4), 2, 2) four.mat <- matrix(rnorm(16), 4, 4) list(two.mat = two.mat, four.mat = four.mat) }) ``` which should give you a matrix-list. You can slice this matrix-list just like normal, then cbind it in one step: ``` two.mat <-

Hi, I'm working in R 2.11.1 x64 on Windows x86_64-pc-mingw32. I'm experiencing a strange problem in R that I'm not even sure how to begin to fix. I've got a huge (forty-pages printed) simulation written in R that I'd like to run multiple times. When I open up R and run it on its own, it works fine. At the beginning of the program, there's a variable X that I set to 1,

Dear All,   Here's my problem. I have two lists:   > v [[1]] [1] "five" [[2]] [1] "four" [[3]] [1] "three" [[4]] [1] "two" [[5]] [1] "one" [[6]] [1] "six" [[7]] [1] "five"  "four"  "three" "two"   "one"   "six"  [[8]] [1] "four"  "three"

Dear Contributors, I am trying to perform a simulation over sample data, but I need to reproduce the same simulation over 4 groups of data. My ability with for loop is null, in particular related to dimensions as I always get, no matter what I try, "number of items to replace is not a multiple of replacement length" This is what I intend to do: replicate this operation for four

I have four large two-dimensional matrices of which I want to create contour plots. Something like filled.contour(<matrix>) contourplot(<matrix>) works but only gives me one plot at a time. If I combine the four matrices into one three-dimensional matrix, which I'll name "seven", there should be a way of doing something like this contourplot(seven[,,k] for k in 1 to 4)

I have four Polycom 330 phones connected to an asterisk system. There are other VoIP phones connected too. All of the extensions are four digits beginning with 11. From any of the phones, except the Polycom, picking up the handset to call extension 1103 for example works fine. With the Polycom 330, as I press the second 1 of 1103 it stops taking input and gives me an error. I tried

Hi, I have to do a four point logistics for a dataset. All I have is the absorbance value for different proteins and need to get the four Point values. I have no idea where to start. Any suggestions would be much helpful.

Hello, I have a list of four files. Each file is a list of gene models, and each gene model has attributes in file columns. The sample_week-over-sample_week fold change value foreach i in file is in column 5. The gene model ID is in column 1. To make it more complicated, each gene i may not be found in all four files. I've written R scripts to try to 1) write a function to iterate over each

Hello, Using the svyplot () function, I have plotted four graphs that are saved in four different .png files. I am looking for examples how to redraw the same four graphs within grid viewports so that they stay together on a page. The goal is to create one .png file that will include all four graphs (2 rows, 2 columns). Any help would be appreciated. Thanks, Pradip Pradip K. Muhuri,

List, I've seen this problem in the list archives before, but the only problems I can easily find are using Samba 4 as the DC. In my case, I'm trying to add a Debian Wheezy member server (running the 4.0.9 packages from enterprise samba) into an existing AD domain where the DC's are running Windows Server 2003 R2.

Dear R-users I have four simple linear models, which are all in the form of a*X+b The estimated parameter vectors are a <- c(1,2,3,4) b <- c(4,3,2,1) My goal is to draw a plot where x-axis is X (range from -100 to 100) and y-axis is the sum of all four linear models X <- seq(-100,100, length=10000) plot(X, sum of the four linear functions) I started with a function for summing

I have a Xerox Phaser 3250 printer It worked perfectly under Centos 6 when I told cups that it was a Xerox Phaser 3150. It works under Centos 7, too. I can print pdf files from evince and whatnot with no problems, and printing one, two or three copies of a document from libreoffice works as well. However, if I tell libreoffice to print four copies of a document ("number of copies"

Hi. Please excuse me asking this again. But it really puzzles me. We're installing asterisk at a branch office at NJ (HQ is at Petach-Tikva) It'll need to support 5 POTS lines, 11 analog extensions and four VOIP phones. I wanted to go with a T1 card from digium and a channel bank, but we have a dead line. It has to be up and running by January 1st. I don't have the time to start
