similar to: Equivalent of Hold On MatLab Command

It takes a lot of sweat to generate a composite plot with R ... sigh. I though I was almost done when I met the umpteenth hurdle. I cannot place a nice title on the 2nd plot (raw signal) on the layout. I do not have control on where either the "main" option of "plot" function, or "title", place the text string which keeps dysplaying chopped from above. I also tried

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.

I have to admit I don't fully understand how MatLab's step() function works, but I'm learning that part. Can someone point me to equivalent&related functions in R? thanks Carl

I am running a simulation many times changing one parameter each time and recording the outcome. I have to produce a plot to make a sense of the bunch of numbers I get from every run. My problem is to insert a multi-line text to keep track of which result correspond to which parameter values. A legend does not work in this case because I will plot 2 variables and the corresponding experimental

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?.

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

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

I tried to use R version of package I noticed the original MatLab Pckage is much better documented. I had a look at the R demo code "gtm_demo" and found that variable Y is used in advanced of being created: I wrote my own few lines as follows: inDir <- "C:/Documents and Settings/Monville/Alanine Dipeptide/DBP1/DHA" setwd(inDir) T <-

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

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]]

I noticed taht R cannot understand certain Fortran real constant formats. For instance: c14 <- as.double( 7.785205408500864D-02) Error: unexpected symbol in " c14 <- as.double( 7.785205408500864D" The above "D" is used in Fortran language to indicate the memory starage mode. That is for instructing Fortran compiler to store such a REAL constant in DOUBLE

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

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,

  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

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

Dear all I would like to have some data in the form of a 2-dimensional array (matrix) of lists, so that I can easily find the desired list object by indexing the structure by rows and columns. In matlab there exists a data type called "cell array": a matrix of "cells", which are composite objects very similar to R lists. I know that in R you can create 1-dimensional

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.

Is there a way to force the number of ticks along an axis ? I read the on-line documentation and tried many combinations of all available parameters from functions par(), axTicks(), axis(), plot() ... but no luck ! Thank you very much, Maura tutti i telefonini TIM! [[alternative HTML version deleted]]

Hello I am new to R and I need to convert some dates (numeric format by matlab) to actual dates in R. For instance, Matlab -> 730456 -> >> datestr(730456) ans = 02-Dec-1999 R - > library(zoo) > as.Date(730456) [1] "3969-12-03" I don't not mind the output format but it needs to be right. Many thanks Ed

I am trying to compare the speed of my R code with that reported by the authors of a reference paper who used Matlab. The authors of the paper state "Total CPU time for the algorithm was 10 s for the ...on a modest mobile 2.2 GHz Pentium processor running MATLAB v.6". I am using proc.time (similar to the example shown in ?proc.time) to determine the speed of my R code. Could someone
