Hello all, I am trying to create a matrix of 1s and -1s without any repetitions for a specified number of columns. 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

Hello, This is in response to a post from a couple of years back regarding Kaiser-Meyer-Olkin Measures of Sampling Adequacy. (http://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

After a lot of effort I developed the following function to compute the bounding ellipse (also known a as minimum volume enclosing ellipsoid) for any set of points. This script is limited to two dimensions, but I believe with minor modification the algorithm should work for 3 or more dimensions. It seems to work well (although I don't know if can be optimized to run faster) and

Hi, I wish to use R (version 2.13.1)?from within Matlab(ver R2009a) on windows XP plaform (on both 64 bit and 32 bit OS) . For this I have installed StatConnector (http://rcom.univie.ac.at/download/current/statconnDCOM.latest.exe) for calling R from within Matlab (R2009a) on Windows XP platform. I have added all the files of MATLAB_RLINK folder (downloaded from

While I don't know anything about Box's M test, I googled around and found a Matlab M-file that computes it. Below is my straight-forward translation of the code, without knowing Matlab or the formula (and done in a few minutes). I hope this demonstrates one of Prof. Ripley's point: If you really want to shoot yourself in the foot, you can probably program R to do that for you. [BTW:

Dear Researchers, I wrote two function to fit a circle using noisy data. 1- the fitCircle() is derived from MATLAB code of * zhak Bucher* from the link http://www.mathworks.com/matlabcentral/fileexchange/5557-circle-fit/content/circfit.m 2- the CircleFitByPratt() from MATLAB code of *Nikolai Chernov *from the link

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

Dear R-users, I have an anual info of gross product and I would like to disaggregate to trimestral data. Can I import a matlab library of Quilis? ( http://www.mathworks.com/matlabcentral/fileexchange/24438-temporal-disaggregation-library ) Thanks, Sebasti?n.

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

Hola a todos, es la primera vez que escribo a la lista, espero explicarme correctamente. Trabajo en cronobiología de mamíferos y quiero comenzar a analizar mis datos con R (haciendo análisis de varianza ya llevo unos años en el entorno). Me interesa saber si cada una de mis variables podría ajustarse a una función sinusoidal; tengo medidas cada dos horas para cada una. Querría extraer el mesor y

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 =

Estimados usuarios de R: Tengo que hacer una desagregación temporal de una serie anual del producto interno bruto en trimestral. ¿Hay alguna forma de utilizar la librería en matlab de Quilis de desagregación temporal en R? La libreria se puede bajar de http://www.mathworks.com/matlabcentral/fileexchange/24438-temporal-disaggregation-library Saludos, Sebastián.

Dear R help contributers, I have several x,y scatter plots and I would like to plot them slightly offset, similar to: http://www.mathworks.com/matlabcentral/fx_files/24368/2/content/style4.jpg I've looked all over for this answer with no luck. Just a function name or previous example would probably be enough for me to figure it out. Thank-you in advance, Carly

They seem to have a workaround. I don't know whether anything better is available by now. http://www.mathworks.com/matlabcentral/newsreader/view_thread/163726 HTH, Daniel sarak wrote: > > Is it possible for anyone to upload a youtube video showing how to execute > R commands in Matlab , it's so vital for me .. > -- View this message in context:

Hi! I'm not experienced very experienced with R and i'm looking for a way doing plots like in this example http://www.mathworks.de/matlabcentral/fx_files/23566/2/color_line3.png, which basically it is a 2d plot in which the 3rd dimension (variable) is color coded. I have only seen elsewhere that it is possible to color code dots in a scatter plot and I tried it with success although I

Also note that the functionality discussed could be regarded as a generalization of matrix multiplication where * and + are general functions and in this case we have * replaced by == and + replaced by &.

Hi All, I was looking for a function to find a small matrix inside a larger matrix in R similar to the one described in the following link: https://www.mathworks.com/matlabcentral/answers/194708-index-a-small-matrix-in-a-larger-matrix I couldn't find anything. The above function can be seen as a "generalisation" of the "which" function as well as the function described

Thanks for this interesting suggestion, Morgan. While there is no strict criteria for base R inclusion, one criterion relevant in this case is that the usefulness of a feature be proven in the package space first.
