Hi All, I have a 1000x1000000 matrix. The calculation I would like to do is actually very simple: for each row, calculate the frequency of a given pattern. For example, a toy dataset is as follows. Col1 Col2 Col3 Col4 01 02 02 00 => Freq of ?02? is 0.5 02 02 02 01 => Freq of ?02? is 0.75 00 02 01 01 ? My code is quite simple as the following to find the pattern ?02?.

Dear R-Helpers, I have a matrix where the first column is known. The second column is the result of multiplying this first column with a constant "const". The third column is the result of multiplying the second column with "const"..... So far, I did it like this (as a simplified example): nr.of.columns <- 4 myconstant <- 27.5 mymatrix <- matrix(numeric(0), nrow=5,

Hello, How do I do the following more concisely? Bout[is.na(Bout$bd.n), 'bd.n'] <- 0 Bout[is.na(Bout$ht.n), 'ht.n'] <- 0 Bout[is.na(Bout$dbh.n), 'dbh.n'] <- 0 Would the form of such a command be different between numeric, character and factor columns? . . . between data.frames and matrices? Thanx, DaveT. ************************************* Silviculture

Hi, is there a R function that order a matrix according to some criteria based on the rows(or cols) of that matrix? For example, let's say that my matrix S is composed by n rows S_1, S_2,.., S_n and that I compute some real value g_i=g(S_i) for each row. Then I want to order this set of g_i (from smaller to bigger) and order the correspondent row to the new position. Is it possible (apart

I have a matrix with 2 columns and I want to do fishers exact test for these with the totals for each row being 100 say. The data has the form: 23 12 32 21 12 2 and these represents the tables: 23 12 77 88 32 21 78 79 12 2 88 98 How do I use apply to speed up aclculation of the fisher.exact test? -- Thanks, Jim.

Hello, I am using dovecot with mdbox+sis and I notice an ever increasing disk space usage since I converted mailboxes from Maildir to mdboxes. I have checked with a user and while it actually uses only 65K, his mdbox files on disk are more than 6G. The backup of his mailbox is just 64K. Any suggestions ? Below are some relevant commands: [root at mail ~]# doveadm quota get -u test Quota

Yes I have done it, it is the third command I have run, without any change. a.

I have a 5 column matrix like 12 10 8 6 3 10 9 8 7 5 14 NA 4 NA NA NA 15 NA 10 NA 5 ... I want to select the position of the first entry for each row <=5 for example, for the first row, I want to select the last element and return its position as 5; for th e third row, I want to select the third element and return its position as 3; similarly for the 4th row, I want to select the fifth

Shot in the dark here...haven't tried it myself so no promises. There's probably a much better way to do this but sometimes a little "brute force" helps. Theoretical steps: 1. Stop all mail processes - both SMTP and IMAP. 2. Use "doveadm sync" to backup the user mailbox, e.g., doveadm backup -u user mdbox:/tmp/usermail 3. Verify /tmp/usermail looks reasonable

I'm using Asterisk on a open server (no firewall or NAT) and trying to communicate with a Grandstream BudgeTone 102 SIP phone which is behind NAT. The BudgeTone is at firmware level 1.0.4.30 and Asterisk is from CVS about a week ago. My problem is that I'm only getting half-duplex communication -- I can hear voice from the Asterisk server but the server does not understand any voice from

I am trying to write an efficient function that will do the following: Given an nxm matrix, 10 rows (observations) by 10 columns (samples) for each row, test of all values in the row are greater than a value k If all values are greater than k, then set all values to NA (or something), Return an nxm matrix with the modified rows. If I do this with a matrix of 20,000 rows, I will be waiting until

Question: I created an array with 164 columns and 70 rows. I would like every column to have unit value 1 and the rows 0.1, 0.2, 0.3 up to 7. How can I define that? Thanks for your help!

Hi, I want to write a matrix (n*m) in a file (Text file) such that the file will be as Result file (below). I use the below command but it write all numbers in one column, > write(paste(matrixname),file="test.txt",append=TRUE) how can I do this? Result file: 5 5 -1 -1 -1 -1 8 8 2 7 6 5 6 6 8 2 7 5 Matrix: [,1] [,2] [,3] [,4] [,5]

My last sentence still aplies to the bitrate. We usually use 80kbps, but sometimes we have used 64kbps (e.g. when sourcing from a cellular network). With music you can get the difference, but with voice there's no need to use more bitrate unless you want more quality in the audio itself. -- Xabier Oneca_,,_ El 27/02/2013 15:19, "Jos?

Having problems with the write.table function. I can write a tab delimited file just fine, but for each line in my matrix its inputs a carriage return when i dont want it to. For example my matrix might be: ID V1 V2 V3 FARY1004 1 2 3 FARY2067 2 3 1 FARY4587 2 2 2 And I want the written File to be: FARY1004 1 2 3FARY2067 2 3 1FARY4587 2 2 2 TIA -- View this

Hello, I upgraded from Samba 3.0.2 to 3.0.4 on my Redhat Enterprise system and am now seeing something very strange with POSIX ACL?s. We have several shared directories setup with per-directory group permissions (In other words each directory has its own group in active directory). This way if we want to give a user access to a directory we just add them to the group. After upgrading too 3.0.4

Dear All, I have a file (a matrix) on which I have to compute the correlations. The function "cov" compute the correlations between the columns of a matrix, but I want to compute the correlations between the raws. Can somebody say to me how I can carry out that?
