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

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

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

...cking if this is a source package ... WARNING Subdirectory ?src? contains: arsa.fpp bburcg.fpp Is there a different preferred method to do this? Is it possible to add support for Fortran with the fpp preprocessor (.fpp files) to the R package building process?

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

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:

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) >

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:
