No no...
This is not in R code. I mean that when in the R, I use arules
library, and try to create a 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
=list(lhs=c("a","b","c","d","e","f"),rhs=c("1","2","3","4","5")))
and I just get the rule such:
{c,e,f} => {3}
{c,e,f} => {4}
and the number of items appear in the right hand side of the rules is
always 1.
but I want to see more than 1 item in the right hand side of the rules
such left hand size.in the left hand side I can see 1, 2 or 5 item but
in the rhs just one. I need to have more than 1 item in rhs.
thanks a lot

Quoting "Kevin E. Thorpe" <kevin.tho...@utoronto.ca>:
Four things.
First, I think you meant to send this to r-h...@r-project.org.
Second, I'm not even sure what you are asking. The "examples" you give
are not even valid R code. Are you sure this is an R question? If so,
make your question clearer.
Third, please use a more informative subject than "help."
Fourth. please read the posting guide
