modify rectangle color from image
Hi, I need some suggestion on how I could modify the color on some rectangle that I have created using "image". In other words, I have a 5x5 matrix, say, m. m <- matrix(rnorm(25), nrow=5) I create a grid of rectangles by: image(m) Now I want to change the color of rectangle (3,3) to blue. I don't know how this could be done, and searching the web has given me no hint. Thanks for your help. -- saurav

how to resample (or resize) matrix?
Dear r-help, I have a matrix, suppose, 10x10, and I need the matrix 5x5, having in each cell a mean value of the cells from the initial matrix. Please, point me to a function in R, which can help me doing that. Digging the documentation and mail archives didn't give me a result. Thank you. --- Best regards, Vladimir mailto:wl at eimb....

evaluating string variables
Hello!!! I have a folder (C:/R/) with matrix files, named by number, i.e. 0.mat, 1.mat,...,1250.mat. In this case, they are 5x5 simetric matrices. I would like to compute a property for each matrix and put calculated values into a data frame for posterior ploting and printing. Below there is an example for 7 matrices (0.mat..6.mat) #define data frame L <- data.frame(frame=numeric(7), L=numeric(7)) f0<-1/(5*(5-1)) # f...

using "cochran.test()" as a "mcnemar.test()" ?
Hello all I wish to perform a mcnemar.test() for a 5X5 matrix. Wikipedia tells me (http://en.wikipedia.org/wiki/Cochran_test) I should turn to cochran.test. The only place I found it was in the "outliers" package, but the command cochran.test() acts differently then mcnemar.test() , and doesn't take a table as input. Any ideas on how to...

Extracting data from a list of matrices
Hi, Apologies in advance for the basic nature of my question. I am still very much a rookie when it comes to R. Having googled it, checked Nabble and trial/error to the best of my ability, I have yet to find an easy solution. I am currently working with a list of 5x5 matrices, and want to extract a list consisting of the first number of each matrix. In other words I want to go from: [[1]] [,1] [,2] [,3] [,4] [,5] [1,] a X X X X [2,] X...

Create an AR(1) covariance matrix
...ovariance matrix (AR(1)) for a longitudinal mixed-model simulation. I can do this using nested "for" loops but I'm trying to improve my R coding proficiency and am curious how it might be done in a more elegant manner. To be clear, if there are 5 time points then the AR(1) matrix is 5x5 where the diagonal is a constant variance (sigma^2) and the covariances depend on the number of "steps" between trials. So, the first off-diagonal of the matrix is sigma*rho, the second off-diagonal is sigma*rho^2, the third off-diagonal is sigma*rho^3, and so forth. Any suggestions for...

R extract vertices for polygon
...P) the coordinates of the vertices of the different groups (i.e. 3, 7, 1 . . .) to plot the polygons to delineate the area in which each group "wins" and colour it diferentially. I can make a simple point plot, but I would like to add polygons with full colored area. The example is with a 5x5 matrix, but I'm working with 500 x 500 matrix, so hand work is difficult, Any suggestion will be welcomed.

diag() when input is a numeric scalar
...why when passing a single numeric value that contains any decimals to diag() that the value is silently coerced to a integer for constructing an identify matrix. To me, an input like diag(5.435) seems fairly ambiguous and is more than likely a programming mistake, since it's not obvious that a 5x5 identity matrix should be created. I've seen some code where other writers have been burned on this as well, especially when trying extract diagonal elements but forget about the scalar case. A warning or message would help track this problem down really quickly to force the author to use diag(...

But post-namespace I get: >A <- as(5,"matrix.diag.csr") Error in as(5, "matrix.diag.csr") : No method or default for coercing "numeric" to "matrix.diag.csr" so apparently using exportClass(matrix.diag.csr) isn'...
