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 <- do.call("cbind", mysim["two.mat", ]) four.mat <- do.c...

...rogram, there's a variable X that I set to 1, 5, 10, 20, depending on how sensitive I want the simulation to be to a certain parameter. When I just run one instance of R, the X variable stays the same throughout the program. I have a quad-core machine, so I'd like to take advantage of all four processors. If I open up four sessions and set X to 1, 5, 10, and 20 in those different sessions, then run all four simulations all the way through (about eighteen hours of processing time) at the same time, the variable X ends up being 20 at the end of all four sessions. It's as if R mixed u...

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" "two"   &quot...

...oduce 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 times, where the index for the four groups is in the part of the code: datiPc[[1]][,2]. I have to replicate the following code 4 times, where the changing part is in the data from which I pick the sample, the data that are stored in datiPc[[1]][,2]. If I had to use data for the four samples, I...

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", th...

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,...

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.

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...

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....

I want to place four plots on a page, and I would like to have all four plots share a common title.

I mentioned this on the list last week, and I''ve had some really brilliant feedback off-list as a result. I''d now like to think that ''Four Days on Rails'' is ready for general release (v1.4). It''s available from http://rails.homelinux.org, along with the code for the application described in the document. I''d like to thank the Rails developers for a really cool framework, and I hope ''Four Days on...

I want to trim down a phone number to the last four digits before saving it to the db. How would I do this? For example, 800-555-1212 which could also be 8005551212, i want to save just 1212 (last four digits) only. -- Posted via http://www.ruby-forum.com/.

...ked 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" =4) then I get garbage printed on the printer; many many pages containing one or two lines of garbage characters. If I run the spadmin program and tell it to print a test page, it prints fine. Two test pages, fine. Three, also fine. Four test pa...

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 shopping at ebay, where you don't know what you'll get, and you need to install, under time pressure something...
