Hi all, I have a huge matrix of TRUE/FALSE table like following, and I want to count the number of TRUEs in each row. Instead of looping through each row and do length(Z[Z==TRUE]), I am wondering if there is an easier way of doing this. [,1] [,2] [,3] [1,]TRUE FALSE FALSE [2,]FALSE TRUE TRUE Thank you in advance.

Hi all, I have a list of numbers, e.g., X = c(60593.23, 71631.17, 75320.1), and want to round them so the output is Y = c(60000, 80000, 80000). I tried Y<-round(X,-4), but it gives me Y = c(60000, 70000, 80000). Do anybody know how to round up a number to 10^4? Thank you in advance. Wendy -- View this message in context:

Hi all, I have a matrix, for example [,1] [,2] [1,] 1 3 [2,] 4 6 I want to replicate the matrix twice and add an extra column at the end, which is [,1] [,2] [,3] [,4] [,5] [,6] [,7] [1,] 1 3 1 3 1 3 2 [2,] 4 6 4 6 4 6 5 I found 'rep' only works for vector. Does anyone know how to replicate a matrix, and append the matrix?

Dear all, I am really new to R, and I have problem here. I searched around, but did not get a solution. I have a numetrix matrix (20 by 25) saved in .csv. I read it as >sx<-read.csv("sx.csv",header=F) Then I try to convert it to numeric using >sx<-as.numeric(sx) Error: (list) object cannot be coerced to type 'double' The class of sx is "data.frame". I

anyone who can help me understand- one of my developers reimported openssh snapshot from 0722 into cvs. he sent me the following email about an error he believes is in the snapshot i'm not a cvs-knowledgeable person, so i'm not all that clear on this, but should *.in files be in .cvsignore? i tried checking a later snapshot, but 0722 seems to be the latest one. .cvsignore is dated jun

I have a glm regression (quasi-poisson) of log(mu) on x but I have varying degrees of confidence in the x values, and can attach a numerical weighting to each. Can anyone help me with suggestions of how to analysise this. Is there an R package that would help? Wendy [[alternative HTML version deleted]]

Hi, I have a vector and a matrix. For example, A = [ 12 3 4]; B = [ 4 13 10 2 4 8]; I am comparing A to each column of B using A>B[,ii], so the expected result is C = [ 1 0 0 1 0 0]; I am looking for a way to do this quickly instead of going through the for loop, but haven't had any luck yet? Any advice is appreciated. Thank you very much. Wendy

I now how to expand a LVM by creating a new drive as described here: http://lists.centos.org/pipermail/centos/2007-February/032664.html, the steps are: # pvcreate /dev/sda3 # vgextend VolGroup00 /dev/sda3 Now, I want to know how to expand a LVM without create /dev/sda3? Suppose I have 2 GB free (unpartitioned) and LVM use /dev/sda2 (8 GB). How to make /dev/sda2 become 10 GB? Then resize LVM

Hi all, I have a vector, e.g., A = c(10, 20, 30, 40). This 4 numbers have 4! = 24 different combination. I want to generate a matrix with one combination in one row, so the output would be B = 10 20 30 40 10 40 20 30 ... Does anyone know how to do this easily in R? Thank you very much.

RPMsg uses dma_alloc_coherent() to allocate memory to shared with the remote. In this case, as there is no pages setup in the dma_alloc_coherent(), we cannot get the physical address back from the virtual address, and thus, we can set the sg_dma_addr to store the DMA address and mark it already DMA mapped. When virtio vring sees the sg_dma_addr is ready set, do not call dma_map_page(). The issue

Dear all, I want to let R automatically download available files from a website in certain folders. Since the files I need, if exist, are in a certain directory, I used download.file() function with a predesigned directory. However, some of the folders do not have the file I want. When this occurs, my program returns error and terminates. So I wonder if there is any way that I can check if a
