Hi, Try this: #mat1 is the data res<-do.call(cbind,lapply(seq_len(nrow(mat1)),function(i) {new1<-do.call(rbind,lapply(seq_len(nrow(mat1[-i,])),function(j) {x1<-rbind(mat1[i,],mat1[j,]); x2<-(abs(x1[1,1]-x1[2,1])*abs(x1[1,5]-x1[2,5]))+(abs(x1[1,2]-x1[2,2])*abs(x1[1,6]-x1[2,6]))+(abs(x1[1,3]-x1[2,3])*abs(x1[1,7]-x1[2,7]))+(abs(x1[1,4]-x1[2,4])*abs(x1[1,8]-x1[2,8]))}));new1}))

Dear R helpers,   I am working on the scenario analysis pertaining to various interest rates. In this connection I need to form the various combinations as under :   Suppose I have two sets A = (a, b, c) and B = (x,y,z)   Then I can easily form the cominations as (ax, ay, az, bx, by, bz, cx, cy, cz)   However, if I have say 5 variables, then total no of possible combinations will be 3^5 = 243.

Hello Everyone,   This is my first attempt to do something in R. As a precursor to a Willingness to Pay analysis, I want to conduct a Mixed Conditional Logit analysis but am unsure how to proceed because of some nesting within my data.   Below is some data and code that illustrate what I’m trying to do. The data are based on responses to a conjoint survey obtained during pilot testing. In the

http://r.789695.n4.nabble.com/file/n3612530/PSC.r PSC.r Hi all, I just wrote a program in R by editing it in Microsoft Word and then pasting into the text editor of R. The above is the file. And below is what the console complains.... Why doesn't it recognise 'r'?? I have to mention that at least when I typed this first several lines into the console, the first error didn't

virt-v2v moves guests, it doesn't clone them. Therefore we should try to preserve the VM Generation ID (genid) as much as possible. This has the ability to read the genid from VMware VMX files and libvirt XML (but note RHBZ#1598348). It can also write the genid to libvirt (‘-o libvirt’, ‘-o local’) and QEMU (‘-o qemu’). We are missing support currently for all OVF-based formats (hence ‘-i

Dear R-helpers, I am a beginner using R. This is the first question in this list. My question, Is there possible to make combinations with two part column? If I have a number 1,2,3,4,5,6,7,8. I need the result something like below: 1,2,3,4,5 6,7,8 1,2,3,4,7 5,6,8 2,3,4,5,6 1,7,8 1,2,3,6,7 4,5,8 1,2,3,4,8 5,6,7 3,4,6,7,8 1,2,5 .... I would be very happy if anyone could

Does genid exist in oVirt ? If yes, is it already preserved or should it be a new patch ? On Thu, Jul 5, 2018 at 3:44 PM Richard W.M.

Hello all, I found a weird result of the GLM function that seems to be a bug. The code: a=c(rep(1,8),rep(2,8)) b=c(rep(0,8),rep(3,8)) cbind(a,b) model=glm(b~a, family=poisson) summary(model) generates a dataset with two groups. One group consists entirely of zeros, the other of 3's (as happened in a dataset I’m analyzing right now). Since they are count data, one should apply a

Hi! Is there any easy/fast way to combine vectors with restrictions? Example: a=c(1,2,3), b=c(4,5,6), c=c(7,8,9) I want all combinations of this 3 vectors with length=2. Like this: 1,4 1,5 1,6 1,7 1,8 1,9 2,4 2,5 2,6 2,7 ... and so on. Thanks in advance. [[alternative HTML version deleted]]

Hi all, I'm using regular analog phones with * and an ATA186, and I plan to move to cordless phones. But cordless phones usually have no way to flash hook cause there is no hook :-) I seem to recall there is a way to simulate a flash hook using dtmf tones in *, but I can't find which combination to use. More generally, where can I find all those magic cominations to put people on hold,

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:

Dear all, I have a matrix with data and I want to substract from every value the previous element. Let's assume that my vector(matrix) is c<-(1,2,3,4,5) I want to get remove_previous c<-(0,1,2,3,4). How I can do that efficiently in R? I would like to thank you in advance for your help B.R Alex [[alternative HTML version deleted]]

Hi, I have models such as: class Team < ActiveRecord::Base has_many :games end class Game< ActiveRecord::Base belongs_to :team end So there are many (well, 0 to 6) games for each team. Team game has a "score". I would like to get a list of the teams, sorted by the highest scoring game - sort of a ranking based on highest score. I''ve tried several cominations of

Hello everyone The following two commands plot.default(seq(1,5),seq(2,6)) plot(seq(1,5),seq(2,6)) plot nothing. One day ago this would create a simple plot diagram but unfortunately right now no plot appears. ?plot returns Help on topic 'plot' was found in the following packages: Plot a Raster* object (in package raster in library

Guys I am having some serious issues with my call queue and Management is breathing down my neck pretty bad, and I am running out of ideas. I have a single queue for my tech support department. I originally was using the AgentCallbackLogin for them and it tested out great on our testing weekends, but it hasn't worked out since. It would only let one of them take calls at a time, no matter

Hello I would like to calculate a weighted line integral. The integral is calculated by the cells that this lines trasverses (the small cells belong to matrix (m*n) that represent the value that a specific area has. I need to calculate the weights by finding out how much the line touches or impinges inside a cell. The weight is less if a line just touches one of the four edges of a square

I am making some changes to the dial plan at the request of the company president and have run into some problems. I have a couple of layers of menu's and I am not sure how to handle them.
