registering Fortran routines in R packages
Thanks for your email. I try to change the name in lowercase but it conflicts with a C implementation also named halton. So I rename the C function halton2() and sobol2() while the Fortran function are HALTON() and SOBOL() (I also try lower case in the Fortran code). Unfortunately, it does not help since I get init.c:97:25: error: use of undeclared identifier 'halton_'; did you mean

registering Fortran routines in R packages
Dear list, I?m trying to register Fortran routines in randtoolbox (in srt/init.c file), see https://r-forge.r-project.org/scm/viewvc.php/pkg/randtoolbox/src/init.c?view=markup&root=rmetrics. Reading https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Registering-native-routines and looking at what is done in stats package, I first thought that the following code will do the job:

[R-SIG-Mac] rnorm.halton
Hi all, I need to transform classic 32bit Fortran code to 64bit Fortran code, see the discussion [R-SIG-Mac] rnorm.halton. But I'm clearly a beginner in Fortran... Does someone already do this for his package? From here, http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=linux&db=bks&fname=/SGI_Developer/Porting_Guide/ch03.html , I identify the following changes

registering Fortran routines in R packages
Have you tried using tools:::package_native_routine_registration_skeleton()? If you don't like its output, you can easily edit its results and still avoid most pitfalls.

CDF of Sample Quantile
I need to calculate the probability that a sample quantile will exceed a threshold given the size of the iid sample and the parameters describing the distribution of each observation (normal, in my case). I can compute the probability with brute force simulation: simulate a size N sample, apply R's quantile() function on it, compare it to the threshold, replicate this MANY times, and count the

quasi-random sequences
Dear list useRs, I have to generate a random set of coordinates (x,y) in [-1 ; 1]^2 for say, N points. At each of these points is drawn a circle (later on, an ellipse) of random size, as in: > N <- 100 > > positions <- matrix(rnorm(2 * N, mean = 0 , sd= 0.5), nrow=N) > sizes<-rnorm(N, mean = 0 , sd= 1) > plot(positions,type="p",cex=sizes) My problem is to

About Qusi-Monte carlo program
Dear Listers; Does anybody has experience in doing simulation via Qusi-Monte carlo in R or S-plus, if so, could you like to send a small copy of your program to me, I appreciate and thanks in advance!! Frankly speaking, I am struggling to write this kind of program, while I could not figure out, painful!!!!! Best regards, Tony --------------------------------- [[alternative HTML

Cauchy's theorem
In complex analysis, Cauchy's integral theorem states (loosely speaking) that the path integral of any entire differentiable function, around any closed curve, is zero. I would like to see this numerically, using R (and indeed I would like to use the residue theorem as well). Has anyone coded up path integration? -- Robin Hankin Uncertainty Analyst Southampton Oceanography Centre

Mixed conditional logit model
dear all, i wonder whether it is possible to estimate a mixed (random parameters) logit model in R. my dataset only includes conditional explanatory (RHS) variables. i've already searched the R-help archives and found slightly comparable questions but no satisfying answers. an old fashoined conditional logit does not work due to the violation of the iia property. a short description of

Low-discrepancy sequences
Is there any way to _test_ if a given sequence is a low-discrepancy sequence? Or, equivalently, is there any way to measure the "discrepancy" of a sequence? WTIW, ... http://en.wikipedia.org/wiki/Low-discrepancy_sequence ... doesn't look like something implementation-friendly :-) Alberto Monteiro PS: low discrepany sequences are easily generated in R by the functions

Friday VOIP Users Conference 12:30 PM EDT
This Friday at 12:30 PM EDT We hope to hear more about Astricon and the 1.6 version. A UK legal professional, John Halton of Cripps Harries Hall LLP, joins us to discuss how the law is coming to terms with VOIP. We also expect a visit from Arick of IPKall about what's cooking with them. Most of all, we expect you, the community to share in this experience! For more info see:

Mixed Logit model mlogit error
I am new to R but I have managed to use mlogit to run multivariate logit models successfully. My data violates the Independence of Irrelevant Alternatives assumption and now I would like to run a mixed logit model. It is a "wide" data set with 9 independent (individual) variables and three choices (variable Y). The database is in a cvs file called CAU. This is the code I have run

SSH Client Hangs after logging in to SSHD
I'm not a ssh expert and I don't know if the log is good or bad, but I too am running OpenSHH under OpenServer. I find that after I connect, the return key has no effect unless I first type: stty sane <Ctrl>j If you've hit <ENTER> before that you must first press <Ctrl>j a couple of times to clean out the buffer. After I type the above command, everything

van der waerden test
Hello, I need some help in performing a Van_der_Waerden normal scores test in R. I have two arrays of scores(final on therapy scores from drug and placebo) and want to use the normal scores procdeure to test for significance.

Der Unbenkante Kreig - Mouse Issues
I'm trying to run this game (http://1916.dadiugames.dk/) on Wine 1.2.2, and it works correctly except mouse control. The mouse won't stick to the window and give input, although I've done the MouseWarpOverride fix. Since it's not actually giving out errors I can't really say much about this-- is there a fix that I'm overlooking?

Sangoma Wanpipe 2.3.4-3 compilation fails un der FC2 with Zaptel 1.0.9.2
Thanks for replying. It's there, /usr/src/zaptel and it's valid. The script checks for its existence before compiling. The only thing that's unusual about this zaptel is that it is patched to support KB2 echo can. Gavin: Thanks, already cc'd Sangoma support. Hope they are working today! -----Original Message----- From: Eric "ManxPower" Wieling

The file name end with . (dot) will be renamed at destination fol der
Hi, If the source file name ends with . (dot) the name of the destination file will be cut the dot off. For example: There are "NormalFile" and "NormalFile." under /Apps/TestFolder . I try to rsync this folder. The file "NormalFile." after being copied to destination folder then renamed to "NormalFile", but "NormalFile" is already exist, so
