Attempting to write a vector to a csv file without column headers does not work as documented. The col.names=false feature on the write.table command does however work and it can thus be coerced

Hi, Here i have a matrix like this, OLDMatrix <- X1 X2 X3 ----- ------ ------ 22 24 23 25 27 27 10 13 15 the thing is, im running two function(SUM,COUNT) to get output in another matrix called NEWMatrix NEWMatrix <- c("SUM",colSums(OLDMatrix )) NEWMatrix <- c("COUNT",colSums(!is.na(OLDMatrix

Hello, I am sure I am not the only person with this problem. I have a list with n elements, each consisting of a single column matrix with different row lengths. Each row has a name ranging from A to E. Here is an example: alph[[1]] A 1 B 2 C 3 D 4 alph[[2]] A 1 C 3 D 4 alph[[3]] A 1 D 4 E 5 I would like to create a matrix from the elements in the list with n columns such that the row names

This will start off sounding very easy, but I think it will be very complicated. Let's say that I have a matrix, which shows the number of apples that each person in a group has. OriginalMatrix<-matrix(c(2,3,5,4,6),nrow=5,ncol=1,byrow=T,dimnames=list(c("Bob","Frank","Joe","Jim","David"),c("Apples"))) Apples Bob 2

Dear R-users I need to convert a matrix with three columns in a new array with multiple columns. For example, oldmatrix 1 4 5 1 54 52 1 9 43 2 32 5 2 54 6 2 76 6 3 54 54 3 543 7 3 54 6 newmatrix 5 5 54 52 6 7 43 6 6 if the first column have a new value then add a column to the new matrix and the new[i,j] <- old[,3][i] I write this code, but my initial matrix is very

Dear all, i am stuck with a syntax problem. i have a matrix which has about 500 rows and 6 columns. now i want to kick some data out. i want create a new matrix which is basically the old one except for all entries which have a 4 in the 5 column AND a 1 in the 6th column. i tried the following but couldn´t get a new matrix, just some wierd errors:

Hi all, I need to replace missing values in a matrix by 10 % of the lowest available value in the matrix. I've got a function I've used earlier to replace negative values by the lowest value, in a data frame, but I'm not sure how to modify it... nonNeg = as.data.frame(apply(orig.df, 2, function(col) # Change negative values to a small value, close to zero { min.val =

Hi together I'm pretty new to R, so excuse me if it is a basic question. I have a big dataset (extract of it found in the attachment) of returns from firms. I'd like to compute the Pearson correlation of each firm with the "Market" and the corresponding p-Value. So I thought of making a list of 'cor.test's and then extract the needed values with a for loop. What I did so

Hi when I fit a glm by glm.fit(x,y,family = binomial()) and then try to use the object for prediction of newdata by: predict.glm(object, newdata) I get the error: Error in terms.default(object) : no terms component I know I can use glm() and a formula, but for my case I prefer glm.fit(x,y)... thanks for a hint christoph $platform [1] "i686-pc-linux-gnu" $arch [1]

Dear all, given I have data in a data.frame which indicate the number of people in a specific year at a specific age: n <- 10 mydf <- data.frame(yr=sample(1:10, size=n, replace=FALSE), age=sample(1:12, size=n, replace=FALSE), no=sample(1:10, size=n, replace=FALSE)) Now I would like to make a matrix with (in this simple example) 10 columns (for the

Hi all~ I have a bit of stupid question. And I promise, I have struggled through this and it sort of pains me to post this question... I have the following vector which is are the estimated parameter values output from "optim". $Rates [1] 0.006280048 0.330934659 I want to match the order in the vector by the number in the following matrix: $Index.matrix ALPHA 1 1 BETA 2

This post is NOT a question, but an answer. For readers please disregard all earlier posts by myself about this question. I'm posting for two reasons. First to say thanks, especially to Dimitris, for suggesting the use of errorest in the ipred library. Second, so that the solution to this problem is in the archives in case it gets asked again. If one wants to run a k-fold cross-validation

Hello, We would like to continue a Perl AGI after a Dial() it has done completes following caller hangup. We would like to do this in the same AGI, and not using a new AGI from the 'h' extension. It works fine when the called party hangs up and the 'g' option is used, but not for caller hangup. Is this possible? If not a confirmation that this is the case would be very helpful.

Hello, I have a peculiar problem which I am hoping I can get help on. I am using the write.csv command to write a matrix structure to a file, which I later read in excel. The command works quite well for most strings and numerical values in the matrix structure. However, I have found that when a field in the matrix contains a string of long length, when the matrix is finally written the file

Hi, We're using Asterisk 13.17.0 with PJSIP 2.8 bundled. I've found an issue when Asterisk tries to make a SIP call out using auth, but has the wrong credentials and keeps getting returned a SIP 407, in this example to an OpenSIPs server requiring user auth. Basically this happens: 1. Asterisk sends plain INVITE to OpenSIPs 2. OpenSIPs responds with SIP 407 auth required with a

Hi Is it possible to rsync a RedHat Linux 7.1 machine across a 56K dialup to a Win2000 machine? Thanks Wadeegh

Hi, if we were to use shred to delete a file on a gluster volume, will the correct blocks be overwritten on the bricks? (still using Gluster 3.6.3 as have been too cautious to upgrade a mission critical live system). Cheers, Kingsley.

Is my understanding correct that the body() function currently can't return a function's body intact, in order, and as characters ready for editing? My testing and reading of body()'s help indicate that it can not. Here's what I'm seeing. Consider pasting 1+ and a function containing x^2 together to get 1+x^2 As you can see below, body() reports three

Hello, I'm looking forward to mining some new data six ways from Sunday with a great looking R application named "rattle". May I please have the benefit of this list's informed thoughts on how to debug an installation error?
