Dear expeRts, ?? i? use sapply for loop,?and i want to break it when i needed, how to do that?? e.g. sapply( 1:10, function(i) { if(i==5) break and jump out of the function sapply } ) I want to do it because i have to loop 1000000 times, but i don't know when it will break, that means, it may need break at i=5 or at i=50000, for the possible of the? last case, i don't use for loop,

Does anyone know why? I type

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

Hi,all I have a problem running R.matlab package (under 2.10.1 version). I can set up the matlab server under local machine(run the MatlabServer.m), " And I can use setVariable and evaluate matlab functions in R. But when I ask Matlab to send the value back to R using getVariable function it always returns an error: " ??? Error: A MATLAB string constant is not

Dear R-Experts, here again a question concerning matlab. With the command "matrixM=[1 2 3;4 5 6]" a matrix under Matlab was constructed. It was than stored with the command "save('matrixM.txt','matrixM')". Now I tried to import the data in R with the help of the command "Z=matrix(scan("Z:/Software/R-Programme/matrixM.txt"))" An error

Hi to the list, I am trying to find a way to painlessly move structured data back and forth between R and Matlab (also Octave). For this purpose I found the R.matlab package great help. I wish to use a Matlab -v6 MAT file as an intermediary format, because it is well read by both Matlab and Octave. It is also well read by 'readMat' function in R.matlab package, but that is where I run

Dear R-listers Is there anyone who knows why I get different eigenvectors when I run MatLab and R? I run both programs in Windows Me. Can I make R to produce the same vectors as MatLab? #R Matrix PA9900<-c(11/24 ,10/53 ,0/1 ,0/1 ,29/43 ,1/24 ,27/53 ,0/1 ,0/1 ,13/43 ,14/24 ,178/53 ,146/244 ,17/23 ,15/43 ,2/24 ,4/53 ,0/1 ,2/23 ,2/43 ,4/24 ,58/53 ,26/244 ,0/1 ,5/43) #R-syntax

Hi, All: How might one test Matlab and perl code during "R CMD check"? I ask for two reasons: First, the "fda" package exists in both R and Matlab, and it would help if we could run test examples in Matlab as part of "R CMD check". I tried "R.matlab", but could not get it to work in that context. Second, I have professional

Dear all, I very often use the R function "apply", for speedup purposes. I am now also using MATLAB, and would like to use the same kind of function. I have already asked MATLAB people, and the answer is : "vectorize"... but of course, this is not always possible. So, instead of using a FOR loop all the time, I tried using the bsxfun. So you R people, who might also use MATLAB,

Greetings: We are evaluating the performance of R matrix algebra es as we port a MATLAB R14 script into R. The MATLAB code basically evaluates the AX=B system on sparse matrices that result in output matrices of 100 to 1,000,000 rows/columns. Our R prototype script uses spase base matrices and the methods qr() and qr.coeff(). The following statements are called inside a doubly-nested loop: G

Hello, How to decode speex encoded audio in Matlab if Google doesn't find a library in Matlab that does that? Do you know one?

Hi R, Can I get a comparison between R and MATLAB? How is R efficient than MATLAB? Or what are the weaknesses of R compared to MATLAB?

Hi, Is there any package out there that might help me with translating R code into MATLAB? Using RSiteSearch I found a bunch of "MATLAB stuff" but it all seems to go in the opposite direction, i.e., emulating MATLAB functions in R.
