search for: itemsets

...and i want to perform a simple support count analysis of an itemset which is say not a complete transaction but a subset of a transaction. say {A,B,D} is a transaction and i want to find support of {A,B} even though it never occurs as only A,B in the entire set To this i needed to create a new itemsets class and then use the support function but somehow the answers never seem to tally.

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

...B=1,C=1 B=2,C=1 A=1,B=1,C=1 A=1,B=2,C=1 A=2,B=2,C=1 Are there any function(s) to do this in R ? I tried a combination of expand.grid and combn but the resulting code was very ugly and needed lot of hacks to make it work. I also tried to check the code for arules (which constructs similar "itemsets") but unfortunately its code is in C and I am not very familiar in writing R extensions. Any pointers to functions will be much appreciated. Regards, Saravanan

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 have a data in the following form : CIN TRN_TYP 9079954 1 9079954 2 9079954 3 9079954 4 9079954 5 9079954 4 9079954 5 9079954 6 9079954 7 9079954 8 9079954 9 9079954 9 . . . . . . there are 100 types of CIN (9079954,12441087,15246633,...) and respective TRN_TYP first of all, I want this data to be

Hello, I'm using the eclat function of the arules package (1.0-6) for the identification of frequent itemsets. I need the tidLists, but if I set in the function tidLists=TRUE R crashes (Windows XP Professional SP3, 32 bit, R version 2.12.1 (2010-12-16), reproducible on two different computers) with two different error messages or non at all. Minimum examples are: library(arules) data("Adult")...

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

...eral formal arguments. image(items(ta.eclat), axes = FALSE) delivers no error message but draws axes, which clearly should not be the case In the source code of arules I couldn't find any definition of the image-function (especially no image.R-file.) What I want to do is drawing an image of itemsets as produced by eclat, with blue colors and the item labels at the x-axe. Does anybody know help?

I was wondering if R had a data mining componant and how i could get it. If not do you know anyone who is developing a datamining "plug in" for R Phillip Goodreid -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe"
