I'm testing some different formulations of pairwise interaction point processes in Spatstat (version 1.11-6) using R 2.5.0 on a Windows platform and I wish to simulate them using the Metropolis-Hastings algorithm implemented with Spatstat. Spatstat utilizes Fortran77 code with the preprocessor RatFor to do the Metropolis-Hastings MCMC, but the Makefile is more complicated than any I have worked with. Any suggestions on how I could get started working with the Fortran code in conjunction with RatF...

Hello all, could you tell where is an example of metropolis hasting? Thank you! Tania Sent from my iPod

For those who may be interested, the Highly Available Storage (HAST) project has recently been committed to HEAD in FreeBSD. Obviously, it is still early release and potentially not suitable for a production environment, but may be of interest to those like myself who are on the lookout for a flexible and available network storage option for Xen. More info here: http://wiki.freebsd.org/HAST

Hello, I'm trying to integrate HAST to NAS4Free (FreeBSD 9.1-RC3). Now I have created version 9.1.0.1.531. http://sourceforge.net/projects/nas4free/files/NAS4Free-9.1.0.1/9.1.0.1.531/ Basic CARP + HAST + iSCSI target setup can be done, but very frequently I get hastctl hang when called: /sbin/hastctl status /sbin/hastctl dump Is it better for this method not to call from a script? or

Hi, Do any body know which packages of R I need to go for the below topics? 1. Monte Carlo Markov chain (MCMC) 2. Gibbs Sampling 3. Metropolis Hastings Thanks in advance... Shubha [[alternative HTML version deleted]]

IANACE (I Am Not A Configury Expert :-), but I've been asked to reconfigure LLVM and LLVM-GCC to build with LLVM-GCC (perhaps more accurately, LLVM-G++). The patches to do this are short. In the LLVM tree, this suffices; it looks for LLVM-GCC first, and if that fails, falls back to GCC: Index: llvm.test/autoconf/configure.ac

Hi - I tried to get Daemontools and Unicorn working together a while back - there are issues on USR2 restart because of the pid change - I''m hoping someone in the community will have some understanding of this issue I documented my experience and eventual defeat here : http://log.robotarmyma.de/post/2053448029/daemontools-ubuntu-rvm-bundler-unicorn-install Any help would be received

Currently, to get LLVM to build "Apple-style," it's necessary to copy two files (utils/buildit/GNUmakefile and utils/buildit/build_llvm) into the top-level directory. This is generally a PITA inside of Apple. (I'll spare you the gory details. :-) I'd like to fix this for Apple, and I want to avoid compromising anybody else's build system. I've never used
