The documentation for

add.paramset()
add.constraint()
add.distribution.constraint()

should be updated to be consistent with the documentation for add.signal(), add.indicator() and other quantstrat functions that take a strategy and possibly return one based on the value of the store parameter. For example, the add.signal() documentation has the following return value discussion.

Value

if strategy was the name of a strategy, the name. It it was a strategy, the updated strategy.

Compare the documentation for add.paramset(), add.constraint(), and add.distribution.constraint() with add.signal(), add.indicator(), and other quantstrat functions that accept a strategy and store value. Start by locating these function documentation entries in the package. Done means their Value sections consistently describe the returned strategy name or updated strategy.
