This update brings some big changes and breaks some of the earlier functions. However, with version 1.0.0, from now on, the API will remain stable.
All classes Container
, Deque
, Set
and Dict
now have been modified to be more similar in the way elements can be added, extracted, replaced or removed and therefore share most of their operations. The motivation behind this was to provide specialized data structures that enhance base R list but at the same time still ‘feel’ familiar to R users. As a result, all classes (including Set
and Dict
) now provide named elements and access via name or integer indices similar to base R list, which should users enable to use any of them right from the start without having to read through the manual.
A new class dict.table
is provided, a mixture of data.table and Dict
, which extends data.table
by Dict
operations to enhance data column management.
List of changes
Set
and Dict
provide positional accessDict
, internally all key-value pairs are stored in a hash-table and the elements are always sorted lexicographically by their keysSet
there is a new class OrderedSet
, in which all elements are also always sorted.name = value
as is done in base R lists.add()
now accepts multiple elements passed via name = value
.delete()
(formerly remove
) and discard()
now always work by value. For removing elements by index, now delete_at()
and discard_at()
are used.has()
now always works by value. For checking elements by name, now has_name()
is used.print()
method has been fully revised and now (inspired by the sets package) prints very compact.size()
is now determined by length()
count()
, pop
, and update
are now available for all classesref_

and dict.table
names()
is used to get and set the names as in base R list.[
