similar to: Parrot

I'm curious if any of the core R developers have considered the possibility of hosting R (v2?) on the parrot common runtime environment. Perl6 will generate byte-code for parrot, as will some future version of python. I can imagine both drawbacks and advantages. Some advantages would be fast byte-code execution and freely mixing perl, python and R modules. Anyone looked into this? Tim

I saw the latest parrot release notice on LWN this week and randomly wondered the Perl6 native call interface was like compared to the horrific mess that is Perl5 XS. The answer is that it is a thing of beauty ! Here is the libguestfs hello world example in Perl6 $ dd if=/dev/zero of=guest.img bs=1M count=100 $ mke2fs guest.img $ cat guestfs.p6 use NativeCall; say "Defining stubs";

Hi there, perl6 offers with the NativeCall package a great tool to implement other languages into perl scripts. This has already been done with python, C(++) and perl5. For my use cases - lots of data munging and statistical analyses (climatology/meteorology) - it would be perfect to parse data and call/run models from perl6 and then to do plotting and analyses in R. I saw R does have some

Hi, I have a Parrot Asteroid car media receiver that uses an Android based operating system to function. Is there anything the development crew can do to make the Asteroid stream FLAC audio? the system does have an installer for 3rd party .APK files Best regards, Rob. -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I don't know if this question ought to go here, or rather on R-devel, so please bear with me. I'm interfacing to R via RPy (rpy.sf.net) and an embedded Python interpreter. This is really quite convenient. I use this approach to calculate the correlation coefficient of 1 independent dataset (vector) with 4 dependent vectors. It'd be nice if that could be done in 4 parallel

First off, I like the look of this project. I am considering retargeting my language from .NET & Parrot to LLVM. Its either this, or add a Java backend. I'm probably going to scrap the Parrot support, but it will still leave me with 2 backends. The only reason I am considering LLVM is as a compiler / code generator, not as a VM. Immediately I have several questions regarding

Hi Lang, Thanks a lot for taking time to look into this. I will test the fix soon and let you know the results.

Hi everyone thanks for the replies. The issue was NOT a font problem; I deliberately chose ll1 and l11 as examples of easily confused variable names (evidently these were too easily confused ;-). The code snippet was written as intended, and increment() contained a deliberate, highlighted, bug. I was asking for guidance on avoiding/finding this sort of coding error. That was why I wrote

Hi Arnaud, Apologies for the delayed reply. Thank you for the excellent test case - it exposed a subtle bug in the colorability heuristic. This has been fixed in r153958. In case you are curious, the bug was as follows: the PBQP solver applies applies a simplification step to each matrix. When all elements of a matrix row or column are equal, the value for those elements is "pushed

Hi Lang, The assert is not triggered any longer on my testcases :) I however still get my wrong allocation in some non trivial cases : the pairing constraint is not fulfilled. I have tried to modify the 'ensure pairable' pass (the pass undoing some of the coalescer's work) to always insert register copies for instructions with the pairable constraint, instead of being smart and

Hi Lang, I have reduced the testcase as much as possible. The log of the run and the dumped graphes are attached.

Hi I recently found a bug that was isomorphic to the following: ll1 <- 2 increment <- function(x) { l11 <- 1 return(x+ll1) #bug here } Of course, R is obeying the scoping rules just fine, but I'm evidently not setting the do.what.I.mean.not.what.I.say variable correctly. Now, how do I avoid making this type of error? ... and what is the best tool for tracking it down? --

Hello everybody, i already searched the archieves, but i still don't know what is wrong in my implementation, mybe anybody coud give me some advice ll1<-function(rho,theta,beta1,beta2,beta3,beta4,t,Szenariosw5,Testfaellew5,X1,X2) { n<-length(t) t<-cumsum(t) tn<-t[length(t)] Szenn<-Szenariosw5[length(Szenariosw5)]

Hi Arnaud, Thanks for attaching those files. I'll take a look at them. Commit r153483 adds an option to the PBQP allocator, "-pbqp-dump-graphs", to dump the PBQP graph for each round of each function in a compilation unit. The generated files are named "<module id>.<function>.<round>.pbqpgraph", and contain a simple text representation of the PBQP graph.

This is my first post to this list so I suppose a quick intro is in order. I've been using SPLUS 2000 and R1.6.2 for just a couple of days, and love S already. I'm reading MASS and also John Fox's book - both have been very useful. My background in stat software was mainly SPSS (which I've never much liked - thanks heavens I've found S!), and Perl is my tool of choice for

Would you be able to share the PBQP graphs? I can share the pbqp graph if you send

I've been tossing around some ideas about high-level backends. Say, have LLVM emit Perl code. Sounds whacky but isn't. It's good for the first bootstrapping phase in environments where you don't have a C compiler, where you don't have a cross-compiled binary for download, but you can execute Perl. It also makes a great inspect-the-sources-with-an-editor stage for aspiring
