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

I read the documentation below to mean that: solve_TSP( tsp_input, '2-opt', rep=99 ) will use the 2-opt method on the tsp_input variable 99 times. Catch: I get an "unused input" error. Q: Am I reading the docs (Item 1, below) correctly or is this a problem with solve_TSP ignoring its inputs (Item 2, below). Item 1: solve_TSP doc: > library(TSP) >

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:

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

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

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:

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, I'm trying to create a new S4 class (myMatrix) which for now just extends dgCMatrix (from package Matrix). Then I want to use "[" which is defined in Matrix. Out of the box with "[" (defined in Matrix) I lose the class information and the result is an object of class dgCMatrix. If I specify a "["-method for myMatrix, it is not used because a signature

Hi All, I use arules library, and try to create an association rules for this transaction file: a,c,f,3,4,5 b,e,1,2,4 a,c,e,f,1,3,4,5 d,5 b,c,e,f,1,2,3,4 a,c,e,f,1,3,4,5 b,c,e,f,1,3,4 b,e,1,2,4 a,c,e,f,1,3,4,5 a,b,c,e,f,1,3,4 a,c,d,f,3,4,5 I want to get the rule such: {c,e,f}=> {3,4,5} I used this command: ar=apriori(tr, parameter=list(support=.4, confidence=0.8, maxlen=11), appearance

Question 2a) I am also working with arules package and I have the following problem let suppose the matrix b like: b<-matrix(c(1,1,1,1,1,1,0,0,1,1,1,1,0,0,1,1,0,1,1,1,1,1,1,1),nrow=6) rownames(b)=c("T1", "T2", "T3", "T4", "T5", "T6") colnames(b)=c("It1", "It2", "It3", "It4") bt<-as(b,

Hello everybody! I'm trying some datamining, but i'm having some problems with arule package, in the end of processing R "had to be closed". I already tryied to reinstall the 2.10 version, change the computer and realocated more virtual memory. Does anyone had this problem to? I had a hiphoteses that i have to prepare the data, somehow i don't know. Thanks for helping!!!

I am new to R( but quickly being awed by the range of this it can accomplish, you have one more convert to the useR universe). I have successfully implemented the apriori function and are getting great results. My question concerns how to export these results. I have read lots about write.csv functions and exporting data frames and other standard objects. Im having difficulty working with these S4

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

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) >

I'm in the process of converting some S3 methods to S4 methods. I have this function : setGeneric("enrichmentCalc", function(rs, organism, seqLen, ...){standardGeneric("enrichmentCalc")}) setMethod("enrichmentCalc", c("GenomeDataList", "BSgenome"), function(rs, organism, seqLen, ...) { ... ... ... })

This is pretty far off topic, but seeing as though it directly affects the upcoming Canada on Rails (http://canadaonrails.com) conference in April, I figure it kind of applies to Rails :) I need to find the best place to get discount tickets for the international speakers coming from Europe, and figure you guys would know where the best places are to get deals. I have checked klm.com, and

Hello all, I would like to perform SVM-RFE (Guyon et al. 2002) in R and have only found one implementation of this algorithm. The function belongs to the MCRestimate package but when I try to use it I encounter a problem - the function appears to be missing a required package or other function that I simply cannot find available anywhere.
