Dear R-list members, Just wondering if there is any way to compute the duplication matrix in R. I tried to search for it but only found functions "xpnd" and "vech". Basically for a symmetric n by n matrix A, the duplication matrix D_n is a matrix of dimension n^2 by n(n+1)/2 such that D_n vech(A)= c(A), where c(A) just vectorizes A. The duplication matrix is defined on page

Let say i have a square matrix and applied the 'vech' operator to stack the lower triangular elements into a vector: > Mat <- matrix(1:25, 5) > Mat ? ? ?[,1] [,2] [,3] [,4] [,5] [1,] ? ?1 ? ?6 ? 11 ? 16 ? 21 [2,] ? ?2 ? ?7 ? 12 ? 17 ? 22 [3,] ? ?3 ? ?8 ? 13 ? 18 ? 23 [4,] ? ?4 ? ?9 ? 14 ? 19 ? 24 [5,] ? ?5 ? 10 ? 15 ? 20 ? 25 > Mat[lower.tri(Mat)] ?[1] ?2 ?3 ?4 ?5 ?8 ?9 10 14

just to add to ted's explanation in case it helps to fix the email server problem: below are the two Recipients and one of the two is always contained in the repeated emails that I'm receiving. Also, of course i don't mean to claim that the names contained in below are doing anything to cause the problem . VEC Operator is just an example. There are 3 or 4 others that repeat

Hi all, I wanted to run the hclust (or any other clustering algorithm) on a distance matrix. I have formed the distance matrix as: distmat: a b c d e a 0.00 0.96 1.60 1.60 1.68 b 0.96 0.00 0.96 1.80 2.64 c 1.60 0.96 0.00 0.84 1.80 d 1.60 1.80 0.84 0.00 0.96 e 1.68 2.64 1.80 0.96 0.00

Fellow open video enthusiasts, Chris Blizzard just suggested that with all the Xiph developers attending the OpenVideoConference, we should all get together and discuss the next things to attack for Ogg Theora/Vorbis in Firefox. I think that's a great idea. Assuming that everyone stays for the hackfest on Sunday, we picked 10am on Sunday for a thorough discussion and planning session (1-2

Can anyone please tell whether there is any R function to act as "VEC" and "VECH" operator on Matrix? Yes of course, I can write a user-defined-function for that or else, I can put dim(mat) <- NULL. However I am looking for some R function. Your help will be highly appreciated. Regards, -- View this message in context:

Hi, I'm trying to build samba 4.1.4 on an AIX 5.2.0.0. I'm using GCC v3.3.2 and python 2.7.6 I've configured the build with this command (disabling ACL because of missing headers on my system concerning nfs4 acl): $) LDFLAGS=-lpthread ./configure -C --prefix=/i/infext/samba-4.1.4 --without-acl-support And then I have run the build procedure but it fails on linking libtalloc.so

Dear R-devel, I have tested the code below on R v3.3.2 and v3.3.3 on Mac and Windows. x <- c("2017-01-01 05:00:02", "2017-01-02 03 :M:00") # note the ? :M? in 2nd value as.POSIXct(x) # [1] "2017-01-01 GMT" "2017-01-02 GMT? The time info is lost on the first index as well. And it happens *silently*. On the other hand, if I do: lapply(x, as.POSIXct) #?[[1]]
