I see some code in R to attach finalizers to external pointer references (Register[C]Finalizer). Anyone have an example of how to code the finalizer? R_RegisterCFinalizer accepts a C function, but I can't see how to get it to operate on the pointer, since the pointer is not passed to the function when its called. RegisterFinalizer takes an R closure, but how is it called from R (tried

Thanks Arpith for this pointer but it did not contain what I was looking for. However, I solved my issue by finding that the BitCastInst used when outlining OpenMP parallel region offers a method for retrieving the original value within the bitcast via stripPointerCasts(). So what I did to retrieve omp_outlined..45 is: //bitcast is the third argument of __kmpc_fork_call Value *vcall =

Thanks for your reply. Yes, I was about to recurse over the use list of the argument in the called function. I did not want to pursue that because with this solution, I am going to implement the interprocedural part myself and was wondering if that was not already done. I was not also 100% sure that this will work for any type of arguments. If, based on your response, this is my only solution

Hello, I have been using the USE class to access the use-def chains of different values. However, what I have noticed is that the set of users of a particular value is limited for the appearance of that variable in the current function. How can I get the interprocedural use of a particular value? For example, if a variable *a* is used as an argument in a function call *foo*, the USE analysis

Hi, A question. When I run gelman.diag and gelman.plot with mcmc lists obtained from MCMCregress, the results are following. > post.R <- MCMCregress(Size~Age+Status, data = data, burnin = 5000, mcmc = 100000, + thin = 10, verbose = FALSE, beta.start = NA, sigma2.start = NA, + b0 = 0, B0 = 0, nu = 0.001, delta = 0.001) > post1.R <- MCMCregress(Size~Age+Status, data

Hi Everyone, I posted a similar question about a week ago, but haven't gotten any replies -- I'm afraid that's because my previous question was too vague. Let me try again with a more specific question, and I hope someone can help. NOTE, I know I should be using the newer lme4 package, I just haven't had a chance to update my version of R yet, so the question below relates

I am using a Gentoo Linux machine and trying to mount a remote file system via samba. The following DOES WORK: mount -t smbfs -o username="SMB-SRV\stonyy",password=abc123 //smbsrv/proj /mnt/proj However, I don't really want my username and password visible to the world (yes, I changed the password and everything but the backslash in the username for this posting). So I tried

I'm revisiting the R/S DBI package and was wondering if there is any plan to implement package name spaces in R/S. I've taken to the habit of prepending a few characters to function names in packages to avoid collisions, e.g., dbConnect(). An alternative would be DBI::connect() (s/::/preferred/) which in some ways I find more pleasing. Not having thought about it in detail, it seems pretty

2012/8/25 Iaroslav Markov <ymarkov at cs.stonybrook.edu>: > Can't you do it by performing some analysis on CFG? You can traverse that structure with BFS. And after that for all the BB you have visited more than once, you try to find a parent that has a branch instruction as a terminator. Additionally you ensure that there are no BB with branches as terminators on your way. If such

...surements during 3 months. The measurements were: - Rainfall and runoff events throughout 3monts (runoff being dependant on the rainfall, a coefficient (%) has been made per rainfall event and per 3 months) - Soil texture (3 different textures were differentiated) - Slope (3 classes of slopes) - Stoniness (one time measurement) - Random roughness (throughout 3 months) - Land use (crop land or grazing land) - Vegetation cover (throughout 3 months) - Vegetation height (throughout 3 months, only measured on cropland) - Antecedent moisture content (throughout 3 months) Now I would like to investigate t...

Hi all, I have successfully made and installed both gdal, and proj.4, but still cannot get rgdal to be installed in R. I think i'm very close. I do not have root access, if that matters, i've installed everything locally. I'm using debian on a beowulf cluster. I call: install.packages("rgdal", .libPaths()[1], configure.args =

Hi, I am first year PhD student at Stony Brook University. For one of my projects I am trying to JIT compile and run a C program containing inline assembly using MCJIT but I am not able to. I have cloned and build LLVM-3.1. Below are more details. Arch : x86 OS : Linux ubuntu 2.6.35-22-generic Sample program : test_inline_asm.c ------------------- #include <stdio.h> int main(){ int

Hi, I am using the LLVM JIT infrastructure (MCJIT). I wanted to see if there are any performance gains as the compiler can detect the target CPU at runtime. But, I didn't see any improvement (I compile with -no-mmx and -no-sse). I then tried an experiment, where I compiled the program with clang-3.3, with and without specifying the target cpu as "corei7". I was shocked to see that

Hello, The third argument of the OpenMP runtime call __kmpc_fork_call is the outlined function resulting from omp parallel directive; this is of type kmpc_micro. I can get this argument as an LLVM value by using (callInst->getArgOperand...), but once I get this value, i am stuck in knowing its class type. An example of this value can be: void (i32*, i32*, ...)* bitcast (void (i32*, i32*,

The latest version of `MCMCvis` is now available on CRAN. `MCMCvis` is an R package used to visualize, manipulate, and summarize MCMC output. MCMC output may be derived from Bayesian model output fit with JAGS, Stan, or other MCMC samplers. Improvements since the last CRAN release (0.8.1) include: * ability to calculate and plot prior posterior overlap * ability to return number of effective
