As stated in the title, I am attempting to get association rules for a dataset I am working with.

Unfortunately, the output is 388 rules likes this:

#     lhs     rhs          support      confidence   lift
#[1]   {}  => {2760500500} 0.0005037281 0.0005037281 1   
#[2]   {}  => {2638361901} 0.0005037281 0.0005037281 1   
#[3]   {}  => {2810128001} 0.0005037281 0.0005037281 1   
#[4]   {}  => {2217240500} 0.0005084802 0.0005084802 1

Is this a problem with the code or possibly the dataset I am using? Thanks.

EDIT: in the read.transactions function I used the parameter = list(minlen=2) to prevent this for future reference.
