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,

Thanking you in advance.

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

arules: rules are built on item ordering in the dataframe, rather than
Hi,
I'm trying out the package arules and I'm having a bit of trouble
getting my data to work properly. I have a set of transactions with
the purchased products but each product could appear in a different
column in the data frame. This causes the rules to be built based on
the ordering, which is not significant.
Here is an example:

Help regarding arules package
Dear R experts,
I need help to make my little program efficient which now takes 2hrs to complete.
Using arules package I developed set of rules consisted of 900 rules. Now I want to check whether a lower rule is a subset of a higher premises rule. And if it is a subset of higher premises rule then drop this rule. I am using following code but it takes too much time.

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.

arules package apriori() fn error message XXXX
Hi everybody,
I am using the apriori() fn in the arules package and am encountered an error.
rules <- apriori(rdayst,parameter = list(support = 0.01, confidence = 0.6))
"You chose a very low absolute support count of 0. You might run of memory."
I assume this is related to the value of .01 specified for the support

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: 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"

error in arules package
Hi,
we noticed there was a error in the "arules" package.
After reading the source code, we saw that the Dice similarity index was
"miscalculated" in "dissimilarity" function : an copy-paste from Jaccard
Index was not corrected (2* a_b_c, ie 2*(a+b+c) in the code instead of
2*a +b + c !!!).
After our mail to R-help (21/11/2006), we thought the authors could do

ARULES --> Filtering Rules by RHS
Dear Colleagues,
I would like to only inspect rules that contain a certain label substring on the rhs. In this special case the item labels are built like this:
<itemtype>_<itemvalue> e.g. "Artikelgruppe_E0815" what I want to do is only show rules where "Artikelgruppe" is contained in the rhs - has anybody an idea how this could work?
