similar to: R version of MATLAB symbolic toolbox (variable substitution)

Hi, I'm attending summer School at UCLA (IPAM) on "probabilistics models of cognition". I have been an R-user since v. 1.4.1, but was trained in the frequentist tradition (as most psychologists!). I found that all faculty here use matlab and Murphy's bayes net toolbox. I have not had the need to use matlab before, and would love to stick to R for graphics models and

Is there any R package that implements the same capability of MatLab toolbox called SimBiology ? We are expecially interested in protein-protein interactions and network analysis. As far as I know SimBiology implements a system of ODEs reflecting the kinetic chemical reactions. We would be more interested in stochastic simulations. Thank you in advance. Maura tutti i telefonini TIM!

Is there a wavelet toolbox in R available that can be compared to the Matlab toolbox for wavelets. Does this toolbox offer the possibility to calculated approximations with different wavelets such as Daubechies 2, Daubechies 3, etc, Symmlet 3, Symmlets 5, etc, Coiflets and so on. I have tried to proceed in this way but I was only able to use one sort of wavelets with a pre-fixed order (i.e.

Colleagues, Thanks for the suggestions concerning reading matlab files into R 1. Regarding documentation for the format of matlab files, please see two manuals that I picked up from the matlab websites. The name of the files are: api_guide.pdf api_ref.pdf Use your web browser to access these files in my FTP directory <ftp://ftp.niwa.cri.nz/incoming/mcclatchie> under the appropriate

Hi, I've encountered the following problem at a client. The problem results in one or more of the smbd processing continuously grabbing more and more memory until the system runs out of memory or just becomes unusable due to a low memory condition. This error is extremely serious as the entire server is eventually brought down by one error. After debugging this error at the

Hello my friends Today at FISL (International Forum of Free Software), I''ve had the opportunity to watch a Turbogears presentation. The framework, itself is really weak in comparison to rails, but... When the guy who was making the presentation show the NEW 0.9 TurboGears Toolbox I''ve though: - Isn''t something like that in Rails? Well, after a little googleing

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

Hello, I installed a printer (HP LaserJet 4350n) via CUPS Web Interface. Following this when I run hp-toolbox a dialog claiming that "No Installed HP Devices Found" is displayed. This is true even when I am the root user. This worked as expected on RHEL4 on the same computer (Thinkpad X31) with the same printer. Any thoughts will be appreciated. Thanks, roger wells -- Roger Wells,

A question on p-value of Unit Root Tests using “urca” toolbox There’s a function “punitroot” on unit root probability value punitroot(q, N = Inf, trend = c("c", "nc", "ct", "ctt"), statistic = c("t", "n"), na.rm = FALSE) To my knowledge, “c” means “const” or intercept, “nc” means no const or intercept, and “ct” means time trend

Hi, I'm trying to use R to get eigenvalues and eigenvectors of a matrix whose elements are of the form (2 * lambda), -(lambda + mu), etc. I'd like R to treat this matrix as a numeric matrix without treating lambda and mu as variable names but rather as some sort of atomic quantities (and hence give eigenvectors in terms of mu and/or lambda). MatLab and Mathematica both do this,

Hi! I'm translating some code from Matlab to R and I found a problem. I need to translate Matlab's function 'lsqnonlin' (http://www-ccs.ucsd.edu/matlab/toolbox/optim/lsqnonlin.html) into R, and at the beginning I thought it would be the same as R's 'optim'. But then I looked at the definition of 'lsqnonlin' and I don't quite see how to make

Dear all, I have several files with Matlab code, which I am translating to R. For the zero-level approach, I took the very old shell script from R-help archives, which has made some obvious leg-work such as replacement of "=" with "<-". Now I am translating indexing, matrix operations and function call using this table http://37mm.no/mpy/octave-r.html The problem is, I

Hello, I have a question on unit root test with urca toolbox. First, to run a unit root test with lags selected by BIC, I type: > CPILD4UR<-ur.df(x1$CPILD4[5:nr1], type ="drift", lags=12, selectlags ="BIC") > summary(CPILD4UR) The results indicate that the optimal lags selected by BIC is 4. Then I run the same unit root test with drift and 4 lags:

Hi all, Does anybody have the source code of stochastic volatility models in R or Matlab, for example, the Bayesian based or the simulation based SV estimations as described by Prof Eric Zivot in the following discussion? https://stat.ethz.ch/pipermail/r-sig-finance/2005q4/000501.html -------------- I am wondering what is the current status of estimating stochastic vol models and what's

Hi, The department of economics at our university (Budapest) is planning a course on numerical methods in economics. They are trying to decide which software to use for that, and I would like to advocate R. The other alternative is Matlab. I have found comparisons in terms of computational time for matrix algebra, but I don't think that is relevant: the bottleneck for economists is usually

Hello, I'm looking at porting code written for Matlab to R. However, I don't have sufficient knowledge of Matlab to know whether it's feasible or appropriate. If there is anyone who has any experience in this and could provide some advice, I'd be grateful. TIA, Peter [[alternative HTML version deleted]]

Hi, I have noticed that when using R.matlab that the connection can become quite slow though it remains open. I have to kill both my R session and Matlab to start over and establish a new connection (eg. close(matlab) - seems hung). Is there a way around this? I have been doing the following to establish the connection : Matlab(host="localhost", port=9999, remote=FALSE) matlab<-

Hello, all experts, My major is computer-aied drug design ( main QSAR). Now, my paper need be reviesed, and one reviewer ask me do genetic algorithm coupled with gaussian process method (GA+GP). my data: training set: 191*106 test set: 73*106 here, I need use GA+GP to do variable selection when building the model. In R, there are not GA package like in matlab

Hi, I want to fit some psychophysical data with cumulative gaussians. There is quite a convenient toolbox for matlab called 'psignifit' (formerly known as 'psychofit'). It allows the lower bound of the sigmoid to vary slightly from zero, aswell as the upper bound to vary from one. with these two free parameters, the fitted function is less sensitive to noisy data and outliers.
