Dear R Users, There exists a non-central hypergeometric distribution function in the (MCMCpack) package, and a hypergeometric distribution function in the (stats) package. Is there a function for sampling from an extended hypergeometric distribution? Thanks, Narcyz This message is intended for the addressee named and may con...{{dropped}}

Hello fellow R users, Below are two cases using the "mle" operation from the stats4 package. In CASE 1 the code runs fine, in CASE 2 errors occur: CASE 1 x, alpha_current, s, and n are vectors of the same length. ll_beta<-function(b0=0,b1=0) -sum(s*b0+s*b1*x+s*alpha_current-n*log(1+exp(b0+b1*x+alpha_current))) fit_beta<-mle(ll_beta) CASE 2 The error message is as follows

Hi all, i've to encode voice from a voicemodem. I choose speex 1.0.5 for its quality in voice encoding. I've tried to implement an encoder but unsuccesfully. Here's my code: /* ============ SPEEX stream ENCODER ============================================ */ int SPEEX_EncodePCM(struct _IDA_ClientSocket *IDA,char *buffer,unsigned char *PCM,int num_samples) { /* buffer point to the

The replay gain code has dos line endings in CVS, which causes problems for the Sun compiler, among others. Attached is a patch for the lazy, but it's probably easier to fix locally and commit. -r

Estimados usurios-R: Tengo una lista de alumnos. Hay alguna forma de sacar una tabla de frecuencias por la asistencia a clases mensual. Es decir cuantos días concurrió cada alumno en el mes. Supongamos que la lista está conformada por ocho alumnos, el curso duró 4 días y quiero saber cuantos días concurrió cada uno al curso poniendolo en la columna mes. Quisiera obtener un cuadro así: Alumnos

I just remembered an anomalous result that I stumbled upon whilst tweaking the command-line options to llvm-gcc. Specifically, the -msse3 flag does a great job improving the performance of floating point intensive code on the SciMark2 benchmark but it also degrades the performance of the int-intensive Monte Carlo part of the test: $ llvm-gcc -Wall -lm -O3 *.c -o scimark2 $ ./scimark2 Using

Hi, i'm following encoder example in the manual.pdf of speex documentation. Here's my portion of code: int SPEEX_EncodePCM(struct _IDA_ClientSocket *IDA,char *buffer,unsigned char *PCM,int num_samples) { int ret,c,d=0,nbBytes,ttBytes=0; float PCM_F[160]; char cBits[200]; #ifndef DISABLESPEEX speex_bits_reset(&IDA->speex_bits); for(c=0;c<num_samples;c++) {

the man page for relational operators (see, e.g., ?'<') says: " Binary operators which allow the comparison of values in atomic vectors. Arguments: x, y: atomic vectors, symbols, calls, or other objects for which methods have been written. " it is somewhat surprizing that the following works: '<'(1) # logical(0) '<'() #

Assume we have a function like: foo <- function(x, y) how is it possible to define a binary indexing operator, denoted by $, so that x$y functions the same as foo(x, y)

Dear R-help, After making a typo (reminiscent of FORTRAN 77, I guess) I found the following: > identical(all.equal(2^(-10:10), 2**(-10:10)), TRUE) [1] TRUE I have tried to find the documentation about the ** operator but I was unsuccesful this way: > sessionInfo() Version 2.3.1 (2006-06-01) powerpc-apple-darwin8.6.0 attached base packages: [1] "methods" "stats"

I cannot find any R function or operator that performs a binary AND operation, as performed by Fortran built-in function "iand". Ideally either R operator "&" or "&&" should do that. But some tests proved they do not: > A<- 1 > B <- 2 > A [1] 1 > B [1] 2 > as.numeric(A&B) [1] 1 > as.numeric(A&&B) [1] 1 The binary

Submitted for perusal, comment, improvements, and/or critique. The presentation is in 3 sections: motivation, code, and comment. Motivation: As a new-comer to R from matrix oriented Gauss and Mata, I miss the tools for using a vector (and operator) to ‘sweep’ across a matrix. Here is how these work. If M is I rows by J columns, then one entry corresponding to

Hi, I work with data sets with lots of missing values. We often need to conduct logical tests on numeric vectors containing missing values. I've searched around for material and conversations on this topic, but I'm having a hard time finding anything. Has anyone written a package that deals with this sort of thing? All I want are a group of functions like the ones I've posted

I'm using resample.c from speex in my project, and was testing it by processing the same waveform twice, with a reset() call in the middle, as follows: short *input_data = read_waveform_as_linear(infileName, &rate, &num_samples, &num_channels); SpeexResamplerState *state = speex_resampler_init_frac(num_channels, in_rate, out_rate, in_rate, out_rate, quality, &error);
