R vs octave development strategy (and success)
Hi All, if memory serves me well I recall some paper comparing the relative success in getting mainstream acceptance (as mainstream as statistics can be) of both R and Octave. I remember vaguely that the fact the development strategies (core team vs one main developer) played a major role in the relative success of the two programs. I tried to find this paper, but my goggle skills are failing

How to deploy statistical models built in R in real-time?
.... We have recently published an article about PMML on The R Journal. It basically describes the PMML language and the package itself. If you are interested in finding out more about PMML and how to benefit from this standard, please check the link below. http://journal.r-project.org/2009-1/RJournal_2009-1_Guazzelli+et+al.pdf We have also wrote a paper about open standards and cloud computing for the SIGKDD Explorations newsletter. In this paper, we describe the ADAPA Scoring Engine which executes PMML models and is available as a service on the Amazon Cloud. ADAPA can be used to deploy R mo...

New to R
I'm relatively new to R, and not particularly adept yet, but I was wondering if there was a simply way to simulate missing data that are MAR, MNAR and MCAR. I've got a good work-around for the MCAR data, but it's sort of hard to work with. Josh [[alternative HTML version deleted]]

stats, pics etc on CRAN
Does anyone have some nice ways of showing what's on CRAN? A time-series of the number of packages? A clustered graph of packages by keyword? I'm just after a more impressive way of saying "there's 2600 packages on CRAN" than saying that. Counts of lines of R and C/Fortran code would be interesting... The CRANtastic tag cloud is quite handy... Anything else? Barry

[R-pkgs] New package "list" for analyzing list survey experiments
I know nothing about your package, but "list" is a terrible name for it, as "list" is also the name of a data type in R. -- Jeff

Ejecutar modelo SVM entrenado en R en un ordenador sin R
Hola a todos, el motivo de esta consulta es saber si existe alguna forma de implementar/ejecutar modelos entrenados en R fuera de R. Es decir, por ejemplo un SVM el cual yo lo entreno en R pero quiero que una vez entrenado pueda usarse en un ordenador distinto donde no necesariamente tenga que tener instalado R.   Es decir, sería algo así como pasarlo a librerías C o similar.   Un saludo a todos y

package to fit mixtures of student-t distributions
Hello! I am new to R (before used python exclusively and would actually call the R solution for this issue inside a python notebook, hope that doesn?t disqualify me right of the batch). Right now I am looking for a piece of software to fit a 1D data sample to a mixture of t-distributions. I searched quite a while already and it seems to be that this is a somehwat obscure endeavor as most

usar multiples procesadores en R
Hola a tod en s, estoy realizando unas operaciones con muchos datos con el paquete "vegan", concretamente la función "metaMDS" y me gustaría saber si puedo usar más de un procesador a la vez para acelerar los cálculos.

Heteroscedasticity and mgcv.
I have a two part question one about statistical theory and the other about implementations in R. Thank you for all help in advance. (1) Am I correct in understanding that Heteroscedasticity is a problem for Generalized Additive Models as it is for standard linear models? I am asking particularly about the GAMs as implemented in the mgcv package. Based upon my online search it seems that some
