Dear all, The new package opusminer is now available on CRAN: <https://CRAN.R-project.org/package=opusminer>. opusminer provides an interface to the OPUS Miner algorithm (implemented in C++) for finding the key associations in transaction data. The OPUS Miner algorithm uses the OPUS search algorithm to efficiently discover the key associations in transaction data, in the form of self-sufficient itemsets, using either leverage or lift. opusminer can read transaction data directly from a file, from a list, or from an object of class transactions (from the package arules). Best, Angus
