Abbreviate item labels in transactions, itemMatrix and associations
Description
Provides the generic function and the methods to abbreviate long item labels
in transactions, associations (rules and itemsets) and transaction ID lists.
Note that abbreviate() is not a generic and this arules defines a
generic with the base::abbreviate() as the default.
Usage

## S4 method for signature 'itemMatrix'
abbreviate(names.arg, minlength = 4, ..., method = "both.sides")
## S4 method for signature 'transactions'
abbreviate(names.arg, minlength = 4, ..., method = "both.sides")
## S4 method for signature 'rules'
abbreviate(names.arg, minlength = 4, ..., method = "both.sides")
## S4 method for signature 'itemsets'
abbreviate(names.arg, minlength = 4, ..., method = "both.sides")
## S4 method for signature 'tidLists'
abbreviate(names.arg, minlength = 4, ..., method = "both.sides")
