arules package question- apriori/S4 object export question
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

a question on using arules package
hi, there: I have a question on use of arules package: suppose i have a classification problem with class id = 1 or 0. i put predictors and class ids together and tranform all of them into binary thus i got a binary matrix. When I build the rules from it, I subset the rules to 2 by defining rhs %in% "classid = 1" or "2". (Actually i can build rules from two seperate datasets

arules package: using image() deliveres unexpected results
Dear Collegues, it seems like there is a problem with the image()-method in the package arules. Using an ordninary matrix works fine: image(matrix(rnorm(200), 10, 20), axes = FALSE, col=brewer.pal(9, "Blues") ) delivers an image with blue colors and no axes. Using an object of the class "associations" (arules package) does not work: image(items(ta.eclat), axes = FALSE,

Arules: getting rules with only one item in the left-hand side
Hello, I am using the package arules to generate association rules. I would like to restrict the rules so that in the left-hand side there's only one particular element, let's call it "potatoe". If I do this: rules <- apriori(dtm.mat, parameter = list(sup = 0.4, conf = 0.9,target="rules"), appearance = list(lhs = c("potatoe"))) I get "potatoe"

Arules - predict function issues - subscript out of bounds
Hi, I'm doing a Market Basket Analysis in which I have a list of transaction id's in column 2 and transactions(product names) in column 1. I read this into a transaction file using a txn<-read.transaction(file="data.csv",format='single', rm.duplicates=F, cols=c(1,2)) If I want to use the apriori algorithm everything seems to be running fine. However it is when I want

Error in Arules
Hi everyone, This is my first posting and I am just starting to fumble my way thru R. I have been working thru the Arules package, and I used to be able to use the image function and I get the following message: Error in image.default(basket2) : 'z' must be a matrix I used to be able to plot the image. I only started to get this error when I tried to add x and y axis labels.

[LLVMdev] APInt::sdivrem error?
OK, the code for sdivrem in APInt.h is wrong. Here's what's written: static void sdivrem(const APInt &LHS, const APInt &RHS, APInt &Quotient, APInt &Remainder) { if (LHS.isNegative()) { if (RHS.isNegative()) APInt::udivrem(-LHS, -RHS, Quotient, Remainder); else APInt::udivrem(-LHS, RHS, Quotient, Remainder); Quotient =

[LLVMdev] Need help in converting int to double
Hi Sarath, It would have really helped if you had removed the commented out code and inlined the calls to your homemade helper functions before sending it... You are doing this, in LLVM IR: %0 = getelementptr %Value* %firstArg, i32 0 ; i8** %1 = load i8** %0 ; i8* %2 = bitcast i8* %1 to i64* %3 = getelementptr %Value* %secondArg, i32 0 ; i8** %4 = load i8** %3; i8* %5 = bitcast i8* %4 to i64*

[LLVMdev] Setting priority in instruction selection
I am having a problem with instruction selection with pattern fragments. With my custom target, in order to simplify code generation patterns, I do not allow a constant to be used in an instruction(mainly because they have declare before use semantics). Now the problem I am having is that I cannot get a instruction that contains pattern fragment that uses an immediate value to be selected before
