Dear R users, I want a help to write an algorithm for swapping rows and columns in a matrix thanks in advance [[alternative HTML version deleted]]

Dear R users, I have this program aa<-array(rep(0,27),dim=c(3,3,3)) a<-matrix(rep(1,9),ncol=3) n<-0 for (i in 1:3) {            a[i,]<-a[i,]*(-1)       n<-n+1       aa[,,n]<-a[i,] } but i real want to multiply each row  with -1 according to for loop and after that to put it in the array.  I will give an example for what excaclty want -1 -1 -1  1  1  1  1  1  1 -1 -1 -1 -1

Dear R users, i have this problem with matrices i want to check between two matrices if they are isomorphic i will give an example for what excactly i want   1 -1  1                                 -1  1   1 -1   1  -1                                1  -1  -1   1  1   -1                                1   1  -1 this two matrices are isomorphic beacause if i change the first 2 columns the matrices

Dear R users, i want to put the results of a list to a for loop. i will give an example m1<-matrix(rep(1,15),ncol=5)   ind.sgn <- lapply(1:ncol(m1), combn, x = ncol(m1))  ind.sgn [[1]]      [,1] [,2] [,3] [,4] [,5] [1,]    1    2    3    4    5 [[2]]      [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,]    1    1    1    1    2    2    2    3    3     4 [2,]    2    3    4    5   

Dear R users, I have this problem with memory i guess  AA<-array(rep(0,96096000),dim=c(16,5,3003,400)) Error: cannot allocate vector of size 733.2 Mb can anyone help me,  Thanks in advance... [[alternative HTML version deleted]]

Dear R users, I have a Hadamard matrix 16x15 and i want to put 16x5 submatrices in an array put i have an error. > A1<-matrix(c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, + 1,0,1,0,1,0,1,0,1,0,1,0,1,0,1, + 0,1,1,0,0,1,1,0,0,1,1,0,0,1,1, + 1,1,0,0,1,1,0,0,1,1,0,0,1,1,0, + 0,0,0,1,1,1,1,0,0,0,0,1,1,1,1, + 1,0,1,1,0,1,0,0,1,0,1,1,0,1,0, + 0,1,1,1,1,0,0,0,0,1,1,1,1,0,0, + 1,1,0,1,0,0,1,0,1,1,0,1,0,0,1, +

Dear R users, I want to check matrices when i change the order of the rows or/and the order of the columns or/and the combination of them i will give an example what i want  1  -1  1  1      1  1   1  1 -1  -1 -1 -1    -1 -1  -1  -1   1  1    1  1     1 -1    1   1 these 2 matrices are identical because i change the first row and make it third   1  -1  1  1      -1  1   1  1 -1  -1 -1

Dear R users, I have the "any" function of R  any(ind.c, ind.r, ind.sgn) all are logical factors  it works fine when any of three is true but when they are combined it doesnt work. i tried this any(ind.c, ind.r, ind.sgn,((ind.c==TRUE) & (ind.r==TRUE)), ((ind.c==TRUE) & (ind.sgn==TRUE)),((ind.r==TRUE) & (ind.sgn==TRUE)),  ((ind.c==TRUE) & (ind.r==TRUE) &

Hello I've stumbled upon a problem for inversion of a matrix with large values, and I haven't found a solution yet... I wondered if someone could give a hand. (It is about automatic optimisation of a calibration process, which involves the inverse of the information matrix) code: ********************* > macht=0.8698965 > coeff=1.106836*10^(-8) >

Dear UseRs,Extremely sorry for a basic question. I have a matrix of 19 rows and 365 columns. what i want to do is the following...First i want to leave out column number 1 and want to calculate the row wise mean of the remaining columns, which will obviously give me 365 values in one column, and then subtracting these values from the column i left out i.e. col=1 then i want to leave out column 2

hi guys, I am having an unusual behaviour in puppet with AIX (client node) while copying ssh key from puppet-server to client. here is what i am trying to do; $username = "xyz" $group = "system" $home = "/home" $sshDir = ".ssh" $pub_key = "id_rsa.pub.xyz" 1. creating all users virtually in one go 2. realize them all and copy each of

Dear R-Helpers, I have the following code: data = read.csv("test.csv",header=T,na.strings="-",row.names=1) myData=as.matrix(data) ##myData is a 102x19 matrix myList = alply(myData, 2,function(x){matrix(x,ncol=6,byrow=T)}) ##myList is a list containing 19 matrices with the following names > names(myList) [1] "*ES" "*ET" "*ER"

Hello all, I am developing a basic application using RFacebook. The tutorial Im following is from http://www.liverail.net/articles/2007/6/29/tutorial-on-developing-a-facebook-platform-application-with-ruby-on-rails After I develop the facebook app, and start the server and send a request to http://127.0.0.1:3000/socialrecipe, it takes me to the facebook login page (as expected, so no issues up

I have an application where I have a function to calculate results for a 2-way table or matrix, which returns a matrix with one less row and column. To keep this short, the function below captures the structure: fun2way <- function(f){ if (!length(dim(f)) ==2) stop("only for 2-way arrays") R <- dim(f)[1] C <- dim(f)[2] f[1:(R-1), 1:(C-1)] } Now, I want to

I was using Puppet 0.24.8 and now upgrade the puppet server and client both to 0.25.4 (on 1 machine i.e. server and client), but i am facing some problems. While testing, some of the configs which were/are running fine on older version generates error here; for instance, i have defined the FileSource path in ''/etc/puppet/fileserver.conf'' [myFileSrc] path

Hello all, I have developed a RESTFul webservice in RoR.

Hi all well im using two interfaces.. e.g: eth0:202.188.9.2 is WAN and eth1;192.168.1.1 is LAN.. when im in LAN let say from 192.168.1.9 i cant open WAN IP address e.g: 202.188.9.2 .. why? how to set this?... i only can open 192.168.1.1 .. if possible i want to have both accessable.. thanks rgds amir

hi all, I need to generate ssh authorize keys for a list of users hosted on different servers.the users are active and each one has its public key (id_rsa.pub) hosted in 1 server. now what i need to do is to generate the authorize keys from each of their public key. the key is easily generating if public key hosted on the Node but my problem is that all public keys are hosted in 1 machine with a

Dear R-Helpers, I wonder whether there is a function which cuts a multiple dimensional array along a chosen dimension and then store each piece (still an array of one dimension less) into a list. For example, arr <- array(seq(1*2*3*4),dim=c(1,2,3,4)) # I made a point to set the length of the first dimension be 1to test whether I worry about drop=F option. brkArrIntoListAlong <-

Hello, What is the best way to turn a matrix into a list removing NaN's? I'm new to R... Start: > mt = matrix(c(1,4,NaN,5,3,6),2,3) > mt [,1] [,2] [,3] [1,] 1 NaN 3 [2,] 4 5 6 Desired result: > lst [[1]] [1] 1 3 [[2]] [1] 4 5 6 Thanks! Ben [[alternative HTML version deleted]]
