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

Dear members of samba team I have a problem about samba realizing the function of printing when studying the source of samba-2.2.8. I want to know if the samba can realize printing a big file. For example, the memory of my printing server is limited to 20M, but I want to print a file beyond 20M, how does the samba do? Can samba realize the big file pinting function by cutting the file into a

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 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

Salutations: I have been trying to translate a S-PLUS/ArcInfo (GIS software) application that I wrote on a SGI (IRIX) platform to public domain R and GrassGIS on a Linux platform. I am almost on the verge of abandoning it as I find R to be rather unstable, slow and frustrating. I enclose a section of my code for R experts to examine hoping that they'll point out that all the above three are

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, You don't give the time zone but this is probably due to the clock jumping by one hour when switching to summer time. In UK this happens at 1am and on that day there is no such thing as 01:05, etc., see eg https://www.timeanddate.com/time/change/uk/london In your time zone this probably happens at 2am.

Hi, I''m starting a new application, and want it to be tested out the wazoo. Do people duplicate tests in both unit and functional tests? Say I have a Product model. I write tests that make sure that it acts appropriately (tests the validations and so forth). Is it good practice to also write the functional tests for the same sort of tests (i.e. make sure that the validations are

Hi Folks, I have an internal HDD running under RH7.3. I would like to purchse a second HDD(usb external) of same geometry, and use it as a bootable snapshot of the first internal HDD. I wish to make a whole disk bootable backup regularly via this method. Is this feasible ? How should I approach this ? Any advice and/or documentations are greatly appreciated. Thanks in advance. karhong. --

Hello all, I''ve installed the SearchGenerator from here (http://wiki.rubyonrails.org/rails/pages/SearchGenerator) and have it up and running perfectly when I only have one field in the make_searchable list. When I add a second field to the make_searchable list I get some strange behavior, my results list now displays each result twice. Has anyone else encountered this issue and if

Dear All, I have a very slow deduplication going on on an external usb disk. I'm using it for backups - I rsync the relevent files to the disk and then take a snapshot. I then deduplicate with bedup dedup <disk-mount-point> What I am finding is that it is reporting a deduplication between the data on the disk and its snapshot e.g.: Deduplicated: -

Hello, Just kicking the tyres with PuppetDB (1.1.0) on a test setup with 100-odd nodes running only once an hour by default. Looking at the dashboard the catalog duplication is showing 0.0% which seems a little odd to me. Any way to track down why this is and how to correct it as presumably this is not desired behaviour.

With my qcow2 patch to blktap I contributed a bit to the mess, so here an attempt to clean up and remove at least some of the code duplication in the functions dealing with aio operations. This patch is mostly just moving code. Apart from renaming to get common names and such things, only very few changes are needed as big parts of the code were completely identical and obviously created by
