similar to: Splitting 3D matrix from for loop to generate/save 2D matrices

Yes, you're right. In fact, it's just an adaptation of a matlab command and the author advises using N^4 replications that's why it's the default in the function. The bistochastic matrix is not my subject of interest, but I need it to perform some random tranformation of a vector of incomes. Florent Bresson ----- Message d'origine ---- De : Richard M.

Thanks, I tried someting like this, but computation takes times for large matrices btransf <- function(y,X=length(y)^4) { N <- length(y) bm <- matrix(rep(1/N,N^2),N,N) for(j in 1:X){ coord <- sample(1:N,4,replace=T) d <- runif(1,0,min(bm[coord[1],coord[2]],bm[coord[3],coord[4]]))

I wrote some functions for multiway CANDECOMP, i.e. for least squares fitting of a_{i_1\cdots i_m}\approx\sum_{s=1}^p x^1_{i_1s}x^1_{i_1s}\cdots x^m_{i_ms} with arrays of arbitrary dimension. Reminded me of the good old APL days. I could not find this in the archives, but if it's already there, I would appreciate if someone let me know.

Dear R helpers. I am new to plotting time data using R. wonder how to convert character time info into date in R. I searched over the web but did not find answer. the input character string is something like 03_1993 or 03-1993, so the precision is at month level. I tried the following but failed. #R code below. strptime(c("03_1993"),"%m_%Y")

Hi R Devel, I just ran into a corner case with 'strptime'. Recall that the "%OS" conversion accepts fractional seconds: > strptime("17_35_14.01234.mp3","%H_%M_%OS.mp3")$sec [1] 14.01234 Unfortunately for my application it seems to be "greedy", in that it tries to parse a decimal point which might belong to the rest of the format: >

Hello, Philipp Becker and me, Vaidas Gasiunas, are developers at SAP and part of a team developing a C-like domain-specific language for the SAP HANA in-memory database. We use LLVM as a backend to translate our language to native code, primarily on x86-64 platforms. Our programs are created dynamically, compiled and optimized in a running database. As a result of that we have special

I'm having trouble to install RGtk2 (from source) on Mac OS 10.4.11 (R 2.9.0). The GTK libraries (2.12.11) were installed into /sw/lib via fink. Even if I set the GTK_LIBS to that path, the installation program doesn't seem to find it (see below). libglade is there too but not found. If I install the package from binaries, it fails on load. Would anybody know how to make it work?

Dear expeRts, I struggle with the following problem using snow clusters for parallel computing: I would like to specify l'Ecuyer's random number generator. Base R creates a .Random.seed of length 7, the first value indicating the kind fo random number generator. I would thus like to use the components 2 to 7 as the seed for l'Ecuyer's random number generator. By doing so, I

Dear LLVM community, I would like to know whether it has already been discussed to provide pre-built snapshots of Clang/LLVM trunk available for download. This used to be available through llvm.org/apt, but since this is down I don't know of any alternative but to build it from source. My use case is to test the Boost.Hana library against Clang trunk on Travis, where building from source is

Hi all I'm a master's student from India. I'm very much interested in compilers and infrastructure toolchains. I have been following llvm for past few months, I like the scope of LLVM project and community behind it. I'm hoping to participate in Google Summer of Code 2019 at LLVM. I have intermediate knowledge of modern c++, boost libraries (proto, hana) and basic knowledge

Hi Everyone, I am trying a very simple task to append the Timestamp with a variable name so something like a_2012_09_27_00_12_30 <- rnorm(1,2,1). Tried some commands but it doesn't work out well. Hope someone has some answer on it. Session Info R version 2.15.1 (2012-06-22) Platform: i386-apple-darwin9.8.0/i386 (32-bit) locale: [1]

Hi, when saving a file to this share the permissions (0777) are being ignored under OS X 10.11.5. All files will get these permissions: 0755. I don't know why?

Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

Hello, I try to get per-mailbox-ACLs on dovecot. So, I've modded dovecot.conf: protocol imap { mail_plugins = acl } and plugin { acl = vfile } When I telnet to dovecot an try the command "capability" there is nothing about acl. I need acl for "open-xchange" so I can share Mailboxes over the webinterface. Do I have to create the acl-file manually or does dovecot

I've got another edition of my simulation replication framework. I'm attaching 2 R files and pasting in the readme. I would especially like to know if I'm doing anything that breaks .Random.seed or other things that R's parallel uses in the environment. In case you don't want to wrestle with attachments, the same files are online in our SVN
