similar to: installing the package Rcplex

Hello, I am an R user who wants to solve an optimization problem. To do so, I tried to install the package Rcplex on my computer (Windows7-64), so I did the same as installation Instructions<http://www.geeklog.net/docs/english/install.html> and edited the file "Makevars.win" by adding the path "C:/Program Files/IBM/ILOG/CPLEX_Studio_Preview124/cplex/include" (where the

Dear List, I'm trying to install Rcplex on a ubuntu 64 bit machine, and have not been successful. After installing cplex latest version from ibm's website (everything as standard, except had it installed unto ~/ (the home directory) rather than the default directory). i type (from inside the directory where Rcplex_0.3-0.tar.gz is): >CPLEX_INCLUDE_PATH=~/ILOG/CPLEX/cplex

Dear all, I want to work with R in an optimization problem and I was wondering if there are any available solvers. I found RCplex package but downloading it, I get problems. Why? Is it not free? are there any other solvers available? many thanks! -- View this message in context: http://r.789695.n4.nabble.com/Cplex-solver-and-optimization-in-R-tp3703385p3703385.html Sent from the R help

Hi, I have tried to install the R package Rcplex on windows xp without success. I have only cplex_studio124.win-x86-32 version. I have modified the makevars.win file as indicated in the installation guide ( http://cran.r-project.org/web/packages/Rcplex/INSTALL ), then I zipped the whole folder to order an installation from a zipped file (utils :menuInstallLocal()) The message I had is file

Hi, I am writing a function to plot a pdf of a distribution, GNL.pdf.fn = function(x,mu,sigma,alpha,beta,rho) { y = x-rho*mu cf.fn = function(s){ cplex = complex(1,0,1) temp1 = alpha*beta*exp(-sigma*s^2/2) temp2 = (alpha-cplex*s)*(beta+cplex*s) out = (temp1/temp2)^rho out } temp.fn = function(s){ (Mod(cf.fn(s)))*cos(Arg(cf.fn(s))-s*y) } int.fn =

Dear R-experts, this is not a direct R-problem but I hope you can help me anyway. I would like to minimize || PG-I || over P, where P is a p x p permutation matrix (obtained by permuting the rows and/or columns of the identity matrix), G is a given p x p matrix with full rank and I the identity matrix. ||.|| is the frobenius norm. Does anyone know an algorithm to solve such a problem? And if

Dear all, I am reading with R some measurements vectors from an external device. The length of each vector (containing numbers) is not constant. I would like by doubling the numbers of elements I select to shrink the vector to a new one Let's call the vector I read from the device as oldvector and the shrinked version of it as newVersion I want to have newVersion[1]<-

Found this code: ftp://ftp.samba.org/pub/unpacked/ntdb/lib/ccan/ilog/ilog.c Tests show that it's faster to use the following code in FLAC__bitmath_ilog2_wide(): static const unsigned char DEBRUIJN_IDX32[32]={ 0, 1,28, 2,29,14,24, 3,30,22,20,15,25,17, 4, 8, 31,27,13,23,21,19,16, 7,26,12,18, 6,11, 5,10, 9 }; FLAC__uint32 v; int m;

I have undertaken a small project of writing a Vorbis decoder completely from the spec, with the goal of catching any errors, both typographically and algorithmically, in the spec. My "reference" decoder is also being written in an extremely methodical style, with practically no algorithmic optimization, such that it will be clear that every step has been copied exactly from the spec.

Dear all, I have a large vector (lets call it myVector) and I want to plot its value with the logic below yaxis<-myVector[1] yaxis<-c(xaxis,mean(myvector[2:3]) yaxis<-c(xaxis,mean(myvector[4:8]) yaxis<c(xaxis,mean(myvector[9:16]) yaxis<c(xaxis,mean(myvector[17:32]) this has to stop when the new ..... yaxis<c(xaxis,mean(myvector[1024:2048]) will not find the correspondent number

Dear all, I'm working with Cox-regression, because data could be censored. But in this particular case not. Now I have a simple example: PRO and PRE are (0,1) coded. The response is not normal distributed. We are interested in a model which could describe interaction. But my results are depending strongly in the choose of the contrast option. It is clear that there is some dependence in

Hi There, i want to stream some pictures out of my application using the Theora codec. I can stream to a socket or a file. The current work based on the png2theora example. Something while enconding went wrong: I can see the whole video in VLC, but the complete duration of the file will not be displayed. If i play the video in Firefox, the first 2 seconds will not be played. I think the

Is there a particular reason why CELT grabs 100KB of stack immediately? Is that really required or can that be trimmed down some/a lot? -a

Still trying to stream ogg and have not gotten past a make error in ices2. We www.freespeech.org are an independent media / news site so it would be nice to get this running and support this new format. I'd love to convert all of our 700 streaming video files from from realmedia as well but thats another story! Perhaps this is not the correct forum but it seems like there are a lot of

Hi, I am trying to implement a Vorbis decoder in Java, and I have some problems understanding the file-format specification included with libvorbis. In the header description, there are a few obvious mistakes, which I believe to have solved, but when I try to decode the audio packets, the decoded floor and residue data doesn't seem to make sense at all, and after a few packets, my decoder

Hi, I have a complex-valued vector X in C^n. Given another complex-valued vector Y in C^n, I want to find a permutation of Y, say, Y*, that minimizes ||X - Y*||, the distance between X and Y*. Note that this problem can be trivially solved for "Real" vectors, since real numbers possess the ordering property. Complex numbers, however, do not possess this property. Hence the

I changed the libshout2 and thread module apis. This broke everything. If you are tracking CVS, make sure to update your libshout2 and the thread module. Ices2 and Icecast2 already uses these new changes, which were implemented as part of general cleanup and getting Solaris builds out of clean tarballs. If anyone is having build issues now, on linux or solaris, please let me know. jack. ---

Actually, you don't have to check out ogg and vorbis from CVS. You can just use Vorbis 1.0, if you like. ices was updated to use the Vorbis 1.0 encoding API, and that is the source of the errors the original poster was seing. --- Stan Seibert <p>On Wed, 2002-07-31 at 15:23, D.

Dear R-Team, I have a problem with writing an array to (for example) a .txt-file. Because of the .txt-file must be read from another programm (OPL ILOG), the syntax of the output must be from a special form: name_of_the_object = [ [1,2, ... ], [1,...], ... ]; I think it's easier to understand with a small example: X<-array(1:4,c(2,2)) should be written as: X = [[1,3],

Good Evening Does anyone in the R-help list have experience writing an R wrapper that interfaces with the commercial packages LINGO and/or LINDO.api from R? I have a set of nonlinear/mixed integer problems that solve nicely with LINGO but I would like to use R to set the problems up and analyze/plot the solutions dynamaically. I have searched the archives and have not found any R packages that
