Hello everyone! Is anybody can help me to solve this silly question that unfortunately I haven't found the right way to address it. Supose I have a matrix X[n,n] dimension I would like to calculate the product of the vectors Y=X[1,n]*X[n,1] Then I would like to run the following operation H=if(Y>0) {H[,1]=1} The problem is that the condition "if" works only for the

Dear all, My name is Guillermo I'm trying to write a short program to find all the possible combination in fitting an ARIMA Model. My script is the following: n=rnorm(100)+5 Aux.M=matrix(NA,nrow=100,ncol=2) L=1 for(i in 0:2) {for(j in 0:2) {for(k in 0:2) Aux.M[L,2]=arima(n,order=c(i,j,k),include.mean=TRUE)$aic x1=paste("AR=",i,sep=" ")

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm doing some basic operations on large sparse matrices, for example getting a row. it takes close to 30 seconds on a 3Ghz machine, and shots the memory usage up to the sky. I suspect there are dense intermediary steps (which, if true would defeat the purpose of trying to use sparse representaitons). As much as I try understanding the

The bulk is on my forums - the final post for today is: Results to date: A. It looks like I am going to need a newer compiler for C - xlc/xlC V11 apparently does not understand this code: "/data/prj/cran/R-3.2.3/src/main/memory.c", line 2149.31: 1506-046 (S) Syntax error. I will have to check if R-devel has different code before asking for assistence. +2139 #ifdef

Dear all, Is there anybody who can help me to avoid scientific number in the summary of an lm model? Here there is an example of a usual output of the lm model. Thank you!

Using the Matrix package, how can I create a row-oriented sparse Matrix from scratch populated with some data? By default a column-oriented one is created and I'm aware of the note that the package is optimized for column-oriented ones, but I'm only interested in using it for holding my sparse row-oriented data and doing basic subsetting by rows (even using drop=FALSE). Here is what I

Hi all, I am wondering if this is a bug in the Matrix package or if it something that I am just getting wrong...here is an example: > m = matrix(0,4,4) > dimnames(m) = list(letters[1:4], letters[5:8]) > r = c("a","b","a","d") > m[r,2] = 1 > m e f g h a 0 1 0 0 b 0 1 0 0 c 0 0 0 0 d 0 1 0 0 > M = Matrix(0,4,4) > dimnames(M) =

Dear all, We are trying to install a new Samba server to replace the old one and support Windows 7 clients. But it doesn't work ! When we try to register a machine into th domain, it seems to be accepted by the client but we find these messages in samba logs : > rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(555) > _netr_ServerAuthenticate2: netlogon_creds_server_check

Hello, I am working with a sparse matrix that is approx. 13,900 by 14,100. My goal is to select a row out of the matrix and create a new matrix with that row repeated 13,900 times without having to do any looping. Example: Starting Matrix: exampleMatrix 3 x 4 sparse Matrix of class "dgCMatrix" [1,] 1 . . . [2,] . 1 . 0.5 [3,] . . 1 .. New Matrix:.. newExampleMatrix 3 x 4 sparse

I am getting the following problem with make check-all on the June 24 rc.

Hello again, I may have a common problem to solve but it seems it is harder than I thought... I have 2 internet providers (each one having a different gateway). Behind the router there are around 100 clients that are SNAT-ed. I want some clients to be SNAT-ed to the first provider, while the others to the second one. The following lines should work: iptables -t nat -A POSTROUTING -s

Fine with me as long as eliminating the inconveniences associated with it can be put on the roadmap. The alias instability and the fact that the user has no way to know if s/he should do ?`foo,numeric-method` or ?`foo,numeric,ANY-method` to find the method has been a long-standing problem. H.

Dear Samba Member, i've decide to write to the samba lists in the hope of Your help. Specifically i have at the moment really a problem between Samba 3 (version 3.2.3-3) and Windwos 2008 Enterprise Terminalserver, namilly User, that logon on Samba PDC, could be authenticated, but don't get policy from Samba Netlogon. With both other Terminalserver (Windows Server 2003) works policy

Hello, sorry for the long email, it's a little hard to explain this issue. The gist of it is that the Ubuntu version of parted allowed me to do something which perhaps should not be allowed i.e. creating partitions on a 2.7TB drive when the partition table is not *gpt* but *msdos*. I am trying to configure 2 identical servers, both are Dell Poweredge 2970 machines with 6 disks in them
