Hi all. This has been bugging me for quite some time and I haven't found a solution yet. I was wondering if anyone has any experience with similar scenarios or/and can tell me how this process can be optimized. We use rsync to synchronize JAR libraries on our remote server. The catch here is, that the libraries must go in multiple locations (and not all the locations have all the

I'm often wanting to develop functions whilst manipulating data. But I don't want to end up with a .RData full of functions and data. It might be that I have functions that are re-usable but not worth sticking in a package. So I've tried to come up with a paradigm for function development that more closely follows the way Matlab and Python do it (partly inspired by a confused Matlab

Hi Ahmad, If the Makefile contains only this command, then it is not worth spending time on GoldPlugin. If you are building a large project, then it will be simpler to use GoldPlugin. The steps you are using seem right. You can possibly combine the last two steps (3&4) using only 1 clang command. clang -g -O2 -o .libs/mergedexe .libs/mergedbc.bc -pthread -Wl,--export-dynamic

Hi All, I am migrating a build system of an existing project from 'Object files' based executable generation to 'LLVM Bitcode' files based exe generation and applying OPT pass to LLVM Bitcode. I found out the following 4 step procedure. Please let me know if this is the right procedure or is there any other easy way of doing it. I need to modify 'Makefile' accordingly. I

Greetings, I have a nagging problem with contrasts and I can't seem to resolve it. A factor exists with four levels (lib1, lib2, con1, con2) and when I check the contrasts or set the contrasts to any of the prespecified ones, I do not get the exact contrasts necessary to test the theoretically relevant ones. I need orthogonal contrasts that look just like this matrix: con1 con2

Hi there, When I compile my code with -fdata-sections and -ffunction-sections, I still see some unused string in my shared library (Android). Actually, the strings appear together inside a .rodata.str1.1 section instead of getting their own section. It seems that the C-string literal are considered differently than other constant and the -fdata-sections is not respected in

Hi folks, My system is Windows98 + R1.9.0. The path for my system is c:\perl\bin; c:\mingw\bin; c:\rtools; c:\windows; c:\windows\command; c:\rw1090\bin. I created three files followed the examples in “Writing R extensions” in the directory c:\temp: // X.hh class X { public: X (); ~X (); }; class Y { public: Y (); ~Y (); }; // X.cc #include <iostream> #include "X.hh" static

In the "Writing R Extensions" manual appears this example, to get access to C++ function using the R commands: R> dyn.load(paste("X", .Platform$dynlib.ext, sep = "")) constructor Y R> .C("X_main") constructor X destructor X list() That gives me access to the function "X_main", but how to get access to methods and properties

Hello. I'm playing with libgfapi network disks, over IB and all is working fine, but not disk locking (and true rdma transport). I use virtlockd, and with fuse mount, locking works as expected. But when i converted disk definitions to libgfapi, locks are not created (but qemu starts and works fine). I used direct and indirect locking - same result : qemu working fine, no locks. my

Dear R colleagues, is there an easier way to write R packages for the own use - without RTools and TeX? With R versions < 2.10.0 it was very easy to write a package. Under the path with the package name you wrote a description file and built some directories like "help", "html" and "R" with the special files in a "hand-operated" way. In the next step

Hello, I need to subset my data to only look at the parts that have "holes" in it. I already have a formula to get rid of inconsistencies, but now I need to look only at the problem data to reconfigure it. In my data set where there are multiple "cycles" per "patient," and I want to highlight the patients who have a variable was not measured every cycle. Here's a

I've got a tough to track down problem that seems to be samba related. I've got a directory structure like this: topdir/ lib1/src lib1/include lib2/src lib2/include etc. Each src directory has a makefile in it. VPATH is set to ../include. I'm running cygwin bash and make. In some directories, make can't find files in ../include. In other directories, make finds

Hi, We are rebasing our audio compression subsystem using OPUS rather than SPEEX. The platform is Android but this piece is written in C code: we need to support armv5/armv7/x86 architectures.... and we use the released opus-1.1beta package from here<http://downloads.xiph.org/releases/opus/opus-1.1-beta.tar.gz>. A lot of our OPUS build system + code to drive the audio compression has been

I am trying to get a dll compiled for use with dyn.load. I use R.1.7.1 under Windows. I have tried the following trivial example based on the "Writing R extensions" manual. rtest.h -------- class X { public: X (); ~X (); void Give7(double*); }; class Y { public: Y (); ~Y (); }; rtest.cpp --------- #include <iostream.h> #include "rtest.h" static Y y;

R has long supported user defined binary (infix) functions, defined with `%fun%`. A one line change [1] to R's grammar allows users to define unary (prefix) functions in the same manner. `%chr%` <- function(x) as.character(x) `%identical%` <- function(x, y) identical(x, y) %chr% 100 #> [1] "100" %chr% 100 %identical% "100" #> [1] TRUE

Hi folks I am using the lmer function (in the lme4 library) to analyse some data where individuals are clustered into sets (using the SetID variable) with a single fixed effect (cc - 0 or 1). The lmer model and output is shown below. Whilst the fixed effects are consistent with stata (using xtmixed, see below), the std dev of the random effect for SetID is very very small (3.5803e-05)compared to

Gabe, The unary functions have the same precedence as normal SPECIALS (although the new unary forms take precedence over binary SPECIALS). So they are lower precedence than unary + and -. Yes, both of your examples are valid with this patch, here are the results and quoted forms to see the precedence. `%chr%` <- function(x) as.character(x) `%identical%` <- function(x, y)

Hi, apparently I sent my question about using R and C++ to the wrong list, ironically seeing as that list was called Rcpp. Anyway, I was directed to post my question here. To summarize my current question, I have found two commands that I want to be able to put into a package. The commands are 'R CMD SHLIB X.cc X_main.cc' and
