With this example set.seed(123) A <- matrix(runif(40), nrow = 8) y <- 1:nrow(A) A.laqr <- qr(A, LAPACK=TRUE) both qr.qy(A.laqr,y) and qr.qty(A.laqr,y) give the respective error messages Error in qr.qy(A.laqr, y) : 'b' must be a numeric matrix Error in qr.qty(A.laqr, y) : 'b' must be a numeric matrix However when Lapack is not used as in A.liqr <- qr(A, LAPACK=FALSE) qr.qy(A.liqr,y) and qr....

...an adjustment to the standard errors to study the four regressors that I am interested in. I want to calculate standardized residuals and need the diagonal elements of the hat matrix. I tried to adjust function hat() in the "stats" package for use with sparse matrices. But the method qr.qy does not seem to have a function available for the following signature: signature(qr = "sparseQR", y = "dgCMatrix") - although it indicates that it understands this signature. Following is a minimal example (in my application dd2 is too large for my memory): library(Matrix)...

Hi there, I have a large amino acid csv file like this: input.txt: P,LV,Q,Z P,VL,Q,Z P,ML,QL,Z There is a problem with this file, since LV and VL are in fact the same thing. How do I order each element according to alphabetical order so that the desired output would look like: output.txt: P,LV,Q,Z P,LV,Q,Z P,LM,LQ,Z -- View this message in context:

Hi, I've got two suggestions how to speed up median() about 50%. For all iterative methods calling median() in the loops this has a major impact. The second suggestion will apply to other methods too. This is what the functions look like today: > median function (x, na.rm = FALSE) { if (is.factor(x) || mode(x) != "numeric") stop("need numeric data")

Hello, I have a question about IMAP : I want read a IMAP mailbox in my application. I have found 2 pages about this : http://wiki.rubyonrails.org/rails/pages/HowToReceiveEmailsWithActionMailer/versions/203 http://www.codefetch.com/search?qy=login&lang=ruby But, Rails don''t want use ''net/imap''. So I can''t =( Thank you for your help pmt -- Posted via http://www.ruby-forum.com/.

Good evening list, I'm looking for an R implementation of the "Shuffled Complex Evolution??? (SCE-UA) algorithm after Duan et al. (1993). Does anybody know if there is an extension/ package existing that contains it? Thanks very much for your help! Cheers, Simon Duan QY, Gupta KV, Sorooshian S (1993) Shuffled Complex Evolution Approach for Effective and Efficient Global Minimization. In Jour. of optimization theorie and applications. Vol 76, 3, 501-521

When I use the function cancor of mva package, I found that it doesn't work when one of the matrix has only one column, or both have only one column. The function in Splus 5 with the same name works under those situations. The version of R I am using is 0.63.2 (released on Jan., 1999) on Solaris.

Along with the decomposition the code returns arrays with all first-order partial derivatives of the values/vector wrt the parameters.

Hi. I know that R computes sums of squares based on the diagonal of t(Q) %*% y %*% t(y) %*% Q, where Q comes from the QR-decomposition of the model matrix. Does anyone know where I can find a proof for this result? All Best and Happy New Year, Ethan [[alternative HTML version deleted]]
