screen shot of example:

I have a need to search items in the transaction set by transaction id, like, if I search for 0002, it should list out all the item related to that transaction id.

Answer 1

if I understood you correctly, and trans1 is a transaction object, you can try:

(Grep will get you all transactions containing the string)

inspect(trans1[grep("0002",trans1@itemsetInfo$transactionID)])

update: To get exact match try:

 inspect(trans1[ trans1@itemsetInfo$transactionID=='0002',])
