vecvec 1.1.0

Improvements

• print() method now respects the max.print option and prevents ALTREP materialisation.
• ALTREP vectors are no longer flattened on creation of vecvec objects.

Bug fixes

• Fixed [<- value replacement with NA indices.
• Fixed [<- incorrectly mutating a vecvec when the index selects no elements (e.g. x[FALSE] <- NA). The object is now returned unchanged.

vecvec 1.0.0

The vecvec class has been reimplemented using S7, replacing the previous vctrs implementation. Existing code using vecvec objects should continue to work.

Breaking changes

• Removed new_vecvec(), which is replaced by class_vecvec for S7 consistency.
• Extension packages building new vecvec data types will need to use S7 classes that have the parent class class_vecvec.
• The internal data structure for vecvec objects has been overhauled. In practice these internal indices should not be used by users or developers, as the structure can change in the future to accommodate faster variants for special cases (#7).

New features

• vecvec classed objects now work as matrices and arrays (#15).
• is_vecvec() tests whether an object is a vecvec.
• class_vecvec S7 class and constructor for vecvec objects.
• Added vctrs methods for backwards compatibility and vctrs interoperability.

Improvements

• Substantially faster performance and reduced object size
• Adjacent compatible vectors are now automatically flattened when constructing or modifying a vecvec, reducing fragmentation.

vecvec 0.2.1

Bug fixes

• Fixed missing value handling with is.na() for vecvec objects (#8).

vecvec 0.2.0

New features

• Added vec_math() for vecvec objects.
• Added vec_apply() for applying functions to each vector in a vecvec.

Improvements

• vecvec now works with vctrs::new_rcrd type vectors.
• Added class argument vecvec() to specify subclasses.
• Removed unnecessary cast in Ops with vecvec types.

Bug fixes

• Fixed error when Ops when vecvec and second argument are both length 1.
• Fix casting from vecvec dropping common attributes.
• Fixed vec_proxy_equal() not comparing values across vectors.

vecvec 0.1.0

New features

• new_vecvec() and vecvec() class constructors.
• unvecvec() class deconstructor to reduce back to atomic vectors.
• {vctrs} method dispatch for vecvec data types.
