writing R extension
I'd like to develop a simple library in R in which to save my
particular functions.
I have read the manual on "Writing R Extensions" but it's too
difficult. Someone could help me?
I want only save my personal function (recorded in R-code, not in C) in
"myLibrary" and I want to call it with:
>library (myLibrary).
After this, the functions should be available

naming list entries dynamically
Hello,
I'm new to R and I'd like to dynamically assign names to the entries of a
list.
The situation is: I load several ascii-files from a folder. The data shall
be stored within the list structure, where the file names are assigned to
the list entries.

Matlab inv() and R solve() differences
I submit the following matrix to both MATLAB and R
x= 0.133 0.254 -0.214 0.116

-0.214 -0.674 0.910 0.011
0.116 0.139 0.011 0.180
MATLAB's inv(x) provides the following

Looking for parallel functionality between Matlab and 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,

Equivalents of Matlab's 'find' and 'end'
Sorry if these questions have been asked recently--I'm new to this list.
I'm primarily a Matlab user who is attempting to learn R and I'm searching for possible equivalents of commands that I found very handy in Matlab. So that I don't seem ungrateful to those who may answer, I HAVE determined ways to carry out these processes in 'brute force' sorts of ways in R code,

R and reading matlab compressed files
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

looking for equivalent of matlab's medfilt1 function
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

reducing learning curves?
Hi all,
I am really new to the R language. I am a long time Matlab and C++ user and
I was "forced" to learn R because I am taking a statistics class.
I am seeking to reduce the learning curve to as smooth as possible.
Are there any addon/plug-in features that can reduce the learning curve, for
example, the following features can be very helpful for new learners:

Percentiles in R
Hi there! Still struggling to translate Matlab code into R's tsDyn package.
Here is my question: Is there in R an equivalent function to Matlab's

realized I was wrong. The definition of the Matlab function:

Newbie: colSums() compared with Matlab's sum()
Hi all,
I'm trying to learn R after years of Matlab's experience. Here is an
issue I couldn't solve today.
Consider the following piece of code (written by memory):
for(i in 1:n){
submat <- data[1:i,]
C <- colSums(submat)
}
The problem is that at the first iteration, data[1:1,] reduces to a
vector and colSums returns an error. This sounds really strange to me

Matlab's lsqnonlin
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

R equivalent to Matlab's Bayes net toolbox
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

Does R have an equivalent for Matlab's cell array?
Hi
I have a time series of measurements: every 10 min. a value was logged.
The data look like:

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

How to convert number (matlab) to date

r's optim vs. matlab's fminsearch
Hi,
I'm having a problem converting a Matlab program into R. The R code works
almost all the time, but about 4% of the time R's optim function gets stuck
on a local minimum whereas matlab's fminsearch function does not (or at
least fminsearch finds a better minimum than optim). My understanding is
that both functions default to Nelder-Mead optimization, but what's
different about

Help with Matrix package
Hello all,
A colleague at work set me the challenge to convert some MATLAB
code into R, to see which is faster. We'd seen that benchmark comparing
MATLAB 6.5 to R1.90 (and others), and so I thought that I should be able
to get roughly comparable speeds. The code has lots of multiplications
of matrixes, transposes, and MATLAB's "repmat". I did the code
conversion, and R was about

Dear R experts,
I have a Matlab code which I am translating to R in order to examine and

First of all, I need to reproduce in R the results which were already
obtained in Matlab (to make sure that everything is correct).
There are some matrix manipulations and '\' operation among them in the
code.

K-Means clustering Algorithm
I was wondering if there was an R equivalent to the two phased approach that
MATLAB uses in performing the Kmeans algorithm. If not is there away that I
can determine if the kmeans in R and the kmeans in MATLAB are essentially
giving me the same clustering information within a small amount of error?
