problems linking c++ code
I've been trying to learn about dynamically loading subroutines in R. Ultimately I would like to use this approach to implement some simulations. For the moment though, I've run into a problem compiling c++ code and loading it into R. The 'C/C++' and 'R'code below works fine when compiled and linked with gcc, but gives an error when the library is compiled and linked with

how to get this kind of binomial distribution simulation number?
hai, I want to perform a simulation like this仯伜 Suppose that I have one population ,it's size is 500, is composed of x,y and z. The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I wan to simulate a new same size population based ratio of x, y and z, how can I get and assess the number of x, y and z. ? luan Key Laboratory for Sustainable Utilization of Marine Fisheries

Using LAPACK in C-code to be loaded in R - getting-started-help
I want to speed up computations (involving matrices) by writing some C-code to be loaded. In the C-code, I need to invert matrices etc. As I've understood the "writing R extensions" doc, I can use use #include <R_ext/Linpack.h> in my .c-file and get access to linpack's facilities within my C-code. Is that correct? If so, can anyone point me to examples on how this is

R for Windows crash on new laptop - corrected script
I realized that the script I included in my original post (see below) was written for an older version of rmetasim and will not work with the current version. The only change that need be made to get my script to run with the latest release of rmetasim is to change the command 'simulate.landscape()' to 'sim.landscape()'. My apologies to anyone who tried to use my script and

R for Windows crash on new laptop
I'm trying to use a contributed package (rmetasim) to generate simulated genetic datasets. My scripts work fine when I run them on a Sun workstation running Solaris 7 and when I run them on a ~4 year old laptop PC that I have. However, when I run them on my new laptop (Dell Latitude D410 purchased in August 2005), the simulation will run for a short (variable) period of time, then R

[LLVMdev] stack alignment (again)
Hola LLVMers, I was curious about the state of stack alignment on x86. I noticed there are a few bugs outstanding on the issue. I recently added some code which had the effect of throwing an extra function parameter on our stack at runtime, a 4 byte pointer. Esp is now not 16-byte aligned, so instructions like unpcklps xmm1, dword ptr [eps] cause grief. My AllocaInstr instructions are
