similar to: cor() btwn columns in two matrices - no complete element pairs

Hi everyone, I'm experiencing difficulty getting the results I want when I use a nested for loop. I have a data set to which I perform some calculations, and then try to apply a regression over a rolling window. The code runs, but the regression results I am getting (intercept and slope) are simply the same, repeated again and again in the results matrix. The regression does not seem to be

I have a method I would like multiple controllers to share. Where does it belong? I have it in a file in lib for the moment. It seems it should be here or in controller/application.rb. Thanks in advance. -- Posted via http://www.ruby-forum.com/.

There is no function called 'maxCol' in 2.7.0, so should 'maxCol' be purged from maxCol.Rd and 'max.col' be promoted from an alias (and the file renamed)? from today's R-devel: /usr/local/src/R-devel> head ./src/library/base/man/maxCol.Rd % File src/library/base/man/maxCol.Rd % Part of the R package, http://www.R-project.org % Copyright 1995-2007 R Core

Hi everyone, I want to perform an operation on a matrx that outputs the product of successive pairs of rows. For example: calculating the product between rows 1 & 2; 3 & 4; 5 & 6...etc. Does anyone know of any readily available functions that can do this?

Hi everyone, I have a matrix that has a combination of zeros and NAs. When I perform certain calculations on the matrix, the zeros generate "Inf" values. Is there a way to either convert the zeros in the matrix to NAs, or only perform the calculations if not zero (i.e. like using something similar to an !all(is.na() construct)?

Hi everyone, I'm trying to create an "if" conditional statement with two conditions, whereby the statement is true when condition 1 AND condition 2 are met: code structure: if ?AND? (a[x,y] <condition1>, a[x,y] <condition2>) I've trawled through the help files, but I cannot find an example of the syntax for incorporating an AND in a conditional IF statement.

Hi everyone, I have some data in a matrix, and I want to shift it down by one row. The matrix in question has a date column. Does anyone know of a way to shift the data by one row, whilst preserving the date column in the matrix - i.e. shift the data and leave the date column in the current location?

Hi, I have been using IPsec to communicate between a laptop that tracks -stable and a Linksys BEFVP41 router. I only use it infrequently, but it's been working great. My setup is as described in http://grapeape.alerce.com/linksys-ipsec/article.html (which I am planning to submit to the handbook when it's done). I'm no longer able to make an ipsec connection, and I can't put my

Hi everyone, I posted something similar to this in reply to another post, but there seems to be a problem getting it onto the board, so I'm starting a new post. I am trying to use conditional formatting to select non-zero and non-NaN values from a matrix and pass them into another matrix. The problem is that I keep encountering an error message indicating the ":missing value where

Dear List, I'd really appreciate tip's or code demonstrating how i can achieve some common axis labels integrated into a multiple plot. In my example (below), i'm trying to achieve: -a single "Results 1 (Int)" centered & btwn row 1 and row 2; -a single "Results 2 (Int)" centered & btwn row 2 and row 3; and, -a single "Results 3 (Int)" centered

Hi everyone, Is there a way to vary the increment size in a for loop? For e.g. when incrementing in steps greater than unity.

Hi everyone, I'm having trouble applying the Cor() function to two matrices, both of which contain NAs. I am doing the following: a<-cor(m1, m2, use="complete.obs") ... and I get the following error message: Error in cor(m1, m2, use = "complete.obs") : no complete element pairs Does anyone know how I can apply a correlation, ignoring any NAs?

Hi everyone, I want to extract data from a data set according to dates specified in a vector. I have created a blank matrix with row names (dates) that I want to extract from the full data set. I have then performed a merge to try to o/p rows corresponding to common dates to a results matrix, but the operation did not fill the results matrix. Coulc anyone offer any advice to assist with this

Hi, I'm a complete newbie to Asterisk and have been reading through documentation and sites for the last couple of hours trying to understand what to do to start my learning curve with Asterisk, and am very confused. For starters, what is the difference btwn the 1.2 and 1.4 branches of Asterisk? I can't seem to find a document that describes the changes. Secondly, what is the best

Hello my friends, here is a code I wrote with no loops on matrix that is taking too long (2 seconds and I call him 720 times --> 12 minutes): mat1 and mat2 are both matrix with 103 columns and 164 rows. sequence <- matrix(seq(1 : ncol(mat1))) returns <- apply(sequence, 1, function, mat1= mat1, mat2 = mat2, day = 1) function<- function(mat1, mat2, colNb, day){

Dear List, I often have to merge two or more data frames containing unique row names but with some columns (names) common to the two data frames and some columns not common. This toy example will explain the kind of setup I am talking about: mat1 <- as.data.frame(matrix(rnorm(20), nrow = 5)) mat2 <- as.data.frame(matrix(rnorm(20), nrow = 4)) rownames(mat1) <- paste("site",

Hello, I have a matrix mat1 of dim [1,8] and mat2 of dim[30,8], I want to replace the first row of mat2 with mat1, this is what I do: mat2[1,]<-mat1 but it transforms mat2 in a list I don't understand, I want it to stay a matrix... ----- Anna Lippel -- View this message in context: http://n4.nabble.com/Simple-question-on-replace-a-matrix-row-tp1427857p1427857.html Sent from the R help

I guess this has a simple solution: I have matrix 'mat1' which has row and column names, e.g.: A B C row1 0 0 0 row2 0 0 0 .... rown 0 0 0 I have a another matrix 'mat2', essentially a subset of 'mat1' where the rownames are all in 'mat1' e.g.: B row3 5 row8 6 row54 7 I want to insert the values of matrix mat2 for column B (in reality it could be some or

Hi, I'm getting a bunch of errors since I upgraded to 1.0.0. I understand now that some of them are bug related to release 1.0.0. I'm about to upgrade to 1.0.1. Does anyone know if there are changes in the config file btwn these to versions? Also, what is the best way to do the upgrade? Can I just run ./configure : make : make install : killlall -HUP dovetcot? Best Regards -
