Non repetitive permutations/combinations of elements
...mns. e.g. 1s and -1s for 3 columns can be done uniquely in 2^3 ways. -1 -1 -1 -1 -1 1 -1 1 -1 -1 1 1 1 -1 -1 1 -1 1 1 1 -1 1 1 1 and for 4 columns in 2^4 ways and so on. I finally used the function combn([0 1],3) that I found at the following link http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=7147&objectType=FILE written by Jos van der Geest in Matlab which generated the above. How can I do this is R? I have looked at permn and combn in the combinat library and permutations and combinations in the gtools library and I am still confused as to how to get it to...

File Exchange?
Hi, I've been using R for a number of years, and must say I really like it. This past summer, however, I started using MatLab for a course at school and found the file exchange it has ( http://www.mathworks.com/matlabcentral/fileexchange/loadCategory.do) to be extremely useful. I know that R has packages that people share, and that there's also RForge for more advanced tools... But is there anywhere where people share R scripts? For example, if I make a function that does one specific task, but I don't want to make a form...

r code exchange site?
Does there exist a site where snippets of r code examples can be deposited, such as the one that exists for matlab? http://www.mathworks.com/matlabcentral/fileexchange/ ps I also noted from the main r site http://www.r-project.org/ when you click on the nabble link under the search link, I end up here http://e-nvf.vvvay.net/-td13672.html#a13819 which I don't think is anything to do with R as far as I can tell (but my Russian is not that hot) Yours Hope...

Problem in calling R functions from Matlab

I have added all the files of MATLAB_RLINK folder (downloaded from http://www.mathworks.com/matlabcentral/fileexchange/5051) into the default?Matlab working path?(D:\User\MATLAB) and also added the folder MATLAB_RLINK to the matlab path C:\Program Files\MATLAB\R2009a\toolbox .

R function for Woody Average (Average with alignment)?
Dear R users, I'm looking for a function to align multiple waveforms that contain random phase shifts. The "Woody Average" is one such method -- is there any comparable function already coded for R? Matlab code for this type of average exists [http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=12459&objectType=FILE] but I don't speak matlab. Cheers, Uri

adding 3D arrows to 3D plots
Greetings, I would like to add 3D arrows (i.e. arrow-headed vectors linking X1Y1Z1 to X2,Y2,Z2) to a 3D plot; ideally the sort of plot that can be rotated interactively. Is this possible using plot3d, or another 3d plotter in R? While it is easy to draw segments in plot3d (e.g. below), I haven't figured out how to add arrow heads, or to create 3d arrows from scratch. ##two headless

alpha shape function
Hi all, I want to approximate te shape of an area defined by a set of points. The convex hull is not good enough, but I think that an alpha shape would be fine. I did an RSiteSearch(), google search, RSeek.org search, looked at the CRAN Views, but was unable do find a function in R that computes the alpha shape. Does anyone know if there is such a function in R? Theank you very much. Moacir

R to MATLAB translation
Hi, Is there any package out there that might help me with translating R code into MATLAB? Using RSiteSearch I found a bunch of "MATLAB stuff" but it all seems to go in the opposite direction, i.e., emulating MATLAB functions in R.

Usar R desde Matlab
Hola, He estado utilizando un paquete en Matlab para llamar a R ( http://www.mathworks.com/matlabcentral/fileexchange/5051 ). Es muy sencillo y en cinco minutos he conseguido ejecutar funciones de R. Basta con instalar este paquete en el directorio de trabajo y podremos ver unas funciones para enviar variables a r y trabajar desde matlab. Un ejemplo sería este: >> openR >> a = round(10*rand(4)) a =...

KMO sampling adequacy and SPSS -- partial solution
...tolstoy.newcastle.edu.au/R/help/05/12/17233.html) As it turns out, last year Trujillo-Ortiz et al. at the Universidad Autonoma de Baja California wrote and posted a script for MATLAB that does the job. You can see it (with a discussion of KMO statistics) at http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=12736 Please see their post for documentation/citations/references, etc. I translated the code into R-speak and added a little to the output; the function and an example are copied below. You can just copy/paste to the console to try it out, provided you have the MASS packag...

Mounting Linux Samba Shares on Windows when Active Directory Server is down
Hi, I am running Samba 3.6.19 and making my way through all the Active Directory documentation. I have joined various Linux boxes to a Windows Server 2008 R2 Active Directory domain. Windows 7 users who log on with their domain accounts can mount the correct shares exported by the Linux boxes without having to supply any additional credentials. All working perfectly! However, I have a
