similar to: equivalent function to MatLab 'step' ?

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

  By any chance is there an R equivalent to MATLAB's "whos" command?   I tried searching R and R-seek, but didn't really come up with anything.    There are several items I would like to make sure are stored in the workspace and check their values.   Thank you again for your help and any feedback.     > ?workspace No documentation for 'workspace' in specified

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

Hi I have a time series of measurements: every 10 min. a value was logged. The data look like: 20100914 08:01 3.74 20100914 08:11 3.74 20100914 08:21 3.71 20100914 08:31 4.39 20100914 08:41 3.74 This data spans several months. I would like to group the data per day. In Matlab it is fairly easy to obtain a cell array, of which the first column contains the date of each

Does R have a graphic command equivalent of MatLab Hold On ? I am trying to sabve on a pdf file a composite drawing. I first declare the canvas size, then I define the layout, finally I generate the 4 plots according to layout order. Eventually I close the pdf file (dev.off()). The resulting PDF file contains 2 pages. The first one shows only the layout. The second one shows the whole composite

Hi, I am very new to R so please excuse me if I am asking very obvious questions. I am trying to call a blackbox api function implemented in as a COM object from R. The function definition says that 1. if calling from VBA, the first parameter should be set to "Nothing" 2. if calling from matlab, the first parameter should be set to [] What should be the equivalent for above in R?.

I'm slowly moving my statistical analysis from Matlab to R, and find myself missing two features: a) How do I mimic Matlab's 'hold on'? (I want to show several plots together, when I type two plots one after the other the second overwrites the first) b) How do I mimic Matlab's 'axis'? (after drawing my plots I want to zoom on specific parts- for example, x=0:5,

I submit the following matrix to both MATLAB and R x= 0.133 0.254 -0.214 0.116 0.254 0.623 -0.674 0.139 -0.214 -0.674 0.910 0.011 0.116 0.139 0.011 0.180 MATLAB's inv(x) provides the following 137.21 -50.68 -4.70 -46.42 -120.71 27.28 -8.94 62.19 -58.15 6.93 -7.89 36.94 8.35 11.17 10.42 -14.82 R's solve(x) provides: 261.94 116.22 150.92 -267.78 116.22 344.30 286.68

Hi all, I am currently using the code snippet below to minimize a function which I wasn't able to minimize properly with optim (cliffy surface, constraints, poles). Obviously this iteration is probably the poorest way of implementing such a function and it is expectedly slow. I've already written some vectorized functions, but I'm afraid that I'm missing the "big

Hi, I'm having trouble converting code from MATLAB to R; I want to find the equivalence to MATLAB's function 'fsolve'. I've tried 'nlm', on the squared argument, in R but i did not get the same results. Thankful if helped.

Gracias Carlos. Hasta donde yo entiendo si las hay: El argumento family puede ser: "gaussian" (for minimizing squared error); por lo que tiene que ser numérica "bernoulli" (logistic regression for 0-1 out-comes); binaria por narices "poisson" (count outcomes; requires the response to be a positive integer); numérica también, pues. La única podría ser

> > Why ? I thought you set moodle to use ldaps against AD, so what do you need zentyal for? They installed zentyal and set up a DC to work online with moodle. Imagine if our internet link goes down and students can't authenticate with moodle. I say this because I work in a school in a city in the interior of my state, and the connection is still a little precarious. But the main

Hi everyone, I was just wondering if there is an equivalent in R to the shortcut "Ans" in MatLab whereby I can use the previous result for the current command? This could save a lot of time when hacking in R itself, not from an editor. Thanks, Stephane [[alternative HTML version deleted]]

Is there any way to read these files (standard .mat files, created by matlab version 7 onwards are compressed)? I know that R.matlab doesn't read them (it even says in the file MatlabServer.m "Matlab v7 saves compressed files, which is not recognized by R.matlab's readMat()" (lines 47-8)). I know I should be able to make R call Matlab and transfer data (not that I managed to

I am in a precarious spot.... I run centos 4.0. I upgraded my mod_perl RPM to mod_perl 2.0.1. CGI.pm 3.10 (3.05 comes with centos 4.0) fixes some namespace issues with mod_perl vs mod_perl 2.0.1. I need to upgrade to it to 3.10. Yet that file belongs to the perl rpm that comes with centos. What do people generally do in this type of situation? Do I need to compile a new perl just to upgrade

Hello! I am new to R. I could not find a function analogous to matlab's function buffer, which is used in signal processing. Is there such a function in R? What I need to do is as follows. If I apply the function to the vector c(1:5) for example with a window length 3 and overlapping 2, I need to get a matrix like this: 1 2 3 2 3 4 3 4 5 In matlab this is achieved with the function buffer. Is

Dear users, is anybody of you aware of a R command to perform laplace transform or even its inversion? Thank you very much. Luca

Hola de nuevo. Se me olvidaba la principal razón para utilizar gbm.step del paquete dismo. Como sabéis, los boosted si sobreajustan (a diferencia de los random forest o cualquier otro bootstrap) pero gbm.step hace validación cruzada para determinar el nº óptimo de árboles y evitarlo. Es fundamental. La opción que me queda, Carlos, es hacerlo con gbm, pero muchas veces, y usar el

I'm trying to build compiler-rt for bare-metal arm-none-eabi targets. I don't need any of the existing compiler-rt functionality(though the builtin(s) may be nice). I want to extend it with custom functionality for the arm-none-eabi targets. Can anyone give me some pointers on how to go about doing this. I'm currently doing a combined build of llvm, clang and compiler-rt for both
