similar to: solve_TSP ignores control data, or I'm reading the help doc incorrectly.

Greetings, I am having trouble getting the function reformulate_ATSP_as_TSP to work for me. I have provided a simple example of some of the code I've been using. In particular, I'm not sure why I'm getting the error "Error in dimnames(tsp) <- list(lab, lab) : length of 'dimnames' [1] not equal to array extent" since I created the object ATSP with a valid

Any reference to the appropriate documentation would be most appreciated. I am using the TSP module for clustering of HIV genetic sequences. The distances have already been computed and available as either upper-triangular or square, i.e.: a 1 2 3 b 4 5 c 6 d or a 0 1 2 3 b 1 0 4 5 c 2 4 0 6 d 3 5 6 0 The TSP modules takes in a "dist" object.

While R has library TSP to help solve traveling salesperson problems, does anyone know if it has any libraries to help solve multiple traveling salesperson problems? For instance, suppose one is planning school bus routes and one has multiple buses. Thank you for your time. -- View this message in context:

Does anyone have experience about how to convert a matrix to binaryMatrix using Recommenderlab package? Thanks, Jing [[alternative HTML version deleted]]

Suppose this is my list of transactions: set.seed(200) tran=random.transactions(100,3) inspect(tran) items transactionID 1 {item80} trans1 2 {item8, item20} trans2 3 {item28} trans3 I want to get the 'transpose' of the data, i.e. transactionID items 1 {trans2} item8 2 {trans2} item20 3 {trans3} item28 4 {trans1} item80 I

Hello. I have a general question regarding to clustering of association rules. According to http://cran.r-project.org/web/packages/arules/vignettes/arules.pdf "4.7 Distance based clustering transactions and associations" there is possibility for creating clusters of association rules. I do not understand, how I have to interpret clusters of rules. Let us have next association rules and

This is a Request For Comment, also BCCed to 390 package maintainers of reverse dependencies of the Matrix package. Most users and package authors working with our 'Matrix' package will be using it for numerical computations, and so will be using "dMatrix" (d : double precision) matrix objects M, and indirectly, e.g., for M >= c will also use "lMatrix" (l:

Hola a todos, hace poquito una persona escribía con una duda que se parece, o es, la misma que yo vengo teniendo. Se trata de hacer comparaciones planeadas. Supongamos un experimento en el que participan 4 grupos de niños 8por ejemplo de distintos coles). Estos niños leen palabras largas y cortas, frecuentes e infrecuentes. Por lo tanto el diseño es fácil, un intergrupo "niños" y dos

Dear R developers: I am trying to add a column to a data.frame. The following does the trick by expanding the name of the first data frame with the prefix foo: > data.frame(foo = as.list(data.frame(items = 1:3, bar=1:3)), items = 1:3) foo.items foo.bar items 1 1 1 1 2 2 2 2 3 3 3 3 However, the following special case produces an

Dear R Developers, For package seriation I use Fortran code. I recently got a request to add #if defined(__ICC) || defined(__INTEL_COMPILER) USE IFPORT #endif to the code since the Intel Fortran compiler otherwise has problems with rand(). However, to enable the FPP preprocessor I have to either add a compiler flag (-cpp for gFortran) which is possibly not portable or change the

Hi Martin, package arules heavily relies on ngCMatrix and uses multiplication and addition for logical operations. I think it makes sense that in a mixed operation with one dgCMatrix and one ngCMatrix the ngCMatrix should be "promoted" to a dgCMatrix. The current behavior of %*% and friends is in deed confusing: > m <- matrix(sample(c(0,1), 5*5, replace=TRUE), nrow=5) >

Hello: We trying to configure one machine (Compaq Proliant ML760) with 8 disks (72GB each disk) with RAID. We are thinking to use ext3 and LVM in RedHat 7.2 for manage one filesystem with 500GB. This filesystems have to store near off 5.000.000 of files. Is this possible? Could I resize the filesystems/volume to 1TB? what are the ext3 and LVM limits? someone have tested sismilar environment? I

Dear friends, Do you know how to calculate the CONCAVE hull of a set of points (2- dimensional or n-dimensional)? is that possible in R? (With a "smoothing" parameter of course).

Hello We have successfully set up Red Hat Enterprise Linux ES4 and we are now trying to connect remote clients to connect to it. The problems we are having are as follows: a) If we set connect with telnet, we get the login prompt. If we use any valid login name & password combination (including root), we get the response "Login incorrect" and then the login prompt comes back. How

Dear R users, I'm a bit perplexed with the effect sort has here, as it is different on Windows vs. linux. It makes my factor levels and subsequent plots different on the two systems.
