Hello everyone, Could you please help me find out if R supports matrixes inside matrixes? This is what I would like to do I have an area map of humidity per km. I would like at every cell to keep also information about the height of this area, the current temperature etc. Is something like that supported? I would like to thank you in advance for your help Best Regards Alex

Hi people The script of netlogon is not loaded with login (exactly configured and its respctivas folders and archives they exist and they are with permission 777, view smb.conf) scripts is being loaded manually.Anybody know why?

Hi, I have a function which does a certain task with two vectors, f1 <- function(a,b){body} I also have a list of matrixes (all with the same dim's), and for each column of each matrix in the list I want to use "f1", in such way that it gives the vector "a" in the first argument of "f1". The second argument of the function "b" also comes form a

Hello people, I am in need for testing Marginal Homogeneity for sparse (more then 2X2) matrixes. After searching, what I found by now is that for more then 2 by 2 matrixes, one turns to "stuart maxwell tests" that are available in two packages: irr - see: stuart.maxwell.mh coin - see: mh_test But I couldn't find in the documentation how valid the results are for sparse matrixes,

Hello! I've a problem with the combn function and a set of vector. I would like to make a simple combination where, instead of scalars, i would like to combine vector, in order to form matrixes. In other words, i have nineteen 6-items vectors (for example coef1-coef19), that i would like to combine in n!/k!(n-k)! 6x6 matrixes. I tried with a code like this mma <-

Dear all I have two 10*10 matrixes and I would like to compare theirs contents. By the word content I mean to check visually (not with any mathematical formulation) how similar are the contents. I also know edit that prints my matrix in the scree but still one edit blocks the prompt to launch a second edit() screen. What is the best way to compare these two matrices? I would like to thank you

Dear all, I would like to multiply two matrixes with the different dimension column by column. Let make an example: If I have two matrixes "X" and "Y"as follow: X<- matrix(1:12, nrow=4, ncol=3, dimnames=list(c("A","B","C","D"), c("stage1","stage2","stage3"))) Y<- matrix(1:28, nrow=4, ncol=7,

Hola! I am working on a problem where data points are (square) matrices. Is there a way to make a "vector" of matrices, such that it can be stored in a data.frame? Can that be done with S3? or do I have to learn S4 objects & methods? Kjetil

I have a small idea as to what's going on now; at least, why exporting the class resolves this particular issue. Firstly, when an S4 class is not exported, the associated '.__C__<class>' object is not made part of the package environment. For example, I see: > getAnywhere(".__C__SubMatrix") A single object matching '.__C__SubMatrix' was found It

In a package I've been developing for manipulating genetic data I discovered a problem when indexing into character arrays using NA's: Create a character matrix and a numeric matrix > cmat <- matrix( letters[1:4], ncol=2, nrow=2) > nmat <- matrix( 1:4, ncol=2, nrow=2) Create an index vector containing an NA value > indvec <- c(1,2,NA) Indexing works fine for both

Hi R experts, I have a data recoding problem I cant get my head around - I am not that great at the subsetting syntax. I have a dataset of longitudinal toxicity data (for multistate modelling) for which I want to also want to do a simple Kaplan-Meier curve of the time to first toxic event. The data for 2 cases presently looks like this (one with an event, the other without), with id representing

Hi! We are trying to move from an old machine running SAMBA 2.2.1a to a new machine running RH8 and SAMBA 2.2.5. We tar'ed all shares and moved them over and we then copied /etc/passwd , /etc/group, smbpasswd , secrets.tdb , smb.conf to the new machine. A clip of the global section of smb.conf looks like this: [global] domain master = yes logon path = \\%N\profiles\%u encrypt passwords =

Hi, (sorry for the wall of text; the issue here appears to be rather complicated) I'm seeing a somewhat strange case where checking whether an S4 object inherits from a parent class defined from another package with 'inherits' fails if that object is materialized through a call to 'load'. That's a mouthful, so I've put together a relatively small reproducible example

I tried to post this a few times last week and it seems to have got stuck somehow so I'm trying from a different email in the hope that works. If somehow this has appeared on the list 20 tiems and I never saw any of them I apologize ;-) I'm basically an R-newbie. But I am VERY computer literate. But this has me stumped... All the examples for using the rmeta package to create a

Hello best helpers, I am a new user and I have been struggling for hours. So finally I decide to ask you: If I have a matrix P, and P.2 = P%*%P, and P.3=P.2%*%P is there a function to calculate the power of a matrix?? if not how can i do: for (i in 1:10) {P.i=P^i} after this I need to sum them up and my problem is to combine P and i to P.i can anyone help me please??? Thanks and have a nice

I tried to use gpuCor function in the gputools package of R to calcuate the pairwise correlations of a matrix of 40,000 columns. Becuase there would be memory issues if I use the whole matrix at a time, I splitted the matrix into submatrix of 10,000 columns and then calculate the pairwise correlation of different submatrices. There are altogether 4 submatrices, so I need to calculate the pearson

Hi Martin, John, Thanks for the responses! I've tidied up some of the notes from this mailing list thread and posted them on the bug tracker. John, in this case, I think namespaces are relevant because for non-exported S4 classes, the class information is made available through the '.__C__<package>' symbol in the package's namespace, but not the package environment that
