[0.30.0]

Added

  • combine method added to complement groupby (#903)
  • DimSlices object is now documented interface.
  • Tables can now be converted to AbstractDimArray or AbstractDimStack, guessing the lookup values from dimension columns, thanks to major efforts by @JoshuaBillson and @tiemvanderdeure in (#739)
  • presevedims can be used to preseve dimensions of array during conversion to tables, so that values may themselves be AbstractDimArray (#917)
  • rebuildsliced documented and added to the developer interface
  • Broadcasts improved for all AbstractBasicDimArray, like DimSelectors.
  • groupby accepts name keyword to set the name of the DimGroupbyArray
  • New hasinternaldimensions trait function for lookups that contain multiple dimensions - along with tests. (#991)
  • BREAKING: MergedLookup and other lookups with hasinternaldimensions now return extent/bounds of their "internal" dimensions, not of their indices as they did before. If you merge an X and Y dimension, the extent of that merged lookup will have X and Y elements. (#991)

Fixed

  • Begin/End bugfixed for use as types
  • lookup methods like order, span etc work from all objects consistently (#1071)
  • == for AbstractDimArray with missing values return missing and do not error
  • isequal of AbstractDimArrays takes the dimensions into account

Changed

  • similar for AbstractDimStack has modified behavior more consistent with similar for AbstractArray (#903).

  • Internal const CategoricalEltypes now includes DataType - so that a lookup of types is considered Categorical by default (#876).

  • skipmissing on an AbstractDimStack now skips any missing values in any fiels, rather than missing, which can't actually occur (#1041).

  • Minor changes in coversion to and from tables in some cases.

  • Abstract constructors for AbstractDimArray were removed, as they cause ambiguity hassles. If necessary, extending packages can define methods like these for their own types: DimArray{T}(x::UndefInitializer, dims::Dimension...; kw...) where T = DimArray{T}(x, dims; kw...) DimArray{T}(x::UndefInitializer, dims::MaybeDimTuple; kw...) where T = DimArray(Array{T}(undef, map(length, dims)), dims; kw...) MyDimArray(st::AbstractDimStack; kw...) = DD.dimarray_from_dimstack(MyDimArray, st; kw...)

  • the deprecated index function is now removed completely

  • metadata(obj, dims) no longer works as its ambiguous and not consistently implemented - metadata(obj) does not return a Tuple for each dimension like other similar methods, but the metadata of obj. To get dimension metadata going forward, explicitly use metadata(dims(obj, X))

  • val(obj) no longer returns map(val, dims(obj)) because that's just weird, val seems like it would return parent from that call. lookup does this anyway.

  • Added a D parameter to AbstractDimStack in (#1128) so that its more interoperable with AbstractDimArray

  • Removed two methods that don't have much use and cause lots of invalidations:

    • Base.convert(Type{<:AbstractString}, name::DD.AbstractName) is removed, use string(name) instead.
    • Base.merge(stack::AbstractDimStack, pairs) is removed, use merge(stack, NamedTuple(pairs)) instead.

  • unsafe_set was split out from set in (#926) - set now fixes everything to return a correct object, and unsage_set does not. Use set directly, and unsafe_set in packages or if you really know what youre doing.

  • Removed deprecated LookupArrays and LookupArray
