In OlisaNsonwu/diyar: Record Linkage and Epidemiological Case Definitions in 'R'

R6 2.5.0

• Resolved #195: Slightly clearer message when there is an error in the initialize() method.

• Fixed #214: When a non-portable object inheritance was cloned, methods that were inherited (and not overridden) had the wrong environment. (#215, #217)

• Printing R6 objects, no longer includes .__active__.

R6 2.4.1

• Cloning active bindings previously relied on buggy behavior in as.list.environment(), which would return the active binding's function definition rather than the value from invoking the function. In R 4.0, the behavior will chang so that it returns the value. R6 now no longer relies on this buggy behavior. (#192)

R6 2.4.0

• Fixed #146: Finalizers can now be private methods. (#181)

• Fixed #167: Finalizers now run on cloned objects. (#180)

R6 2.3.0

• Vignettes are no longer included as part of the source package because of their large size. Documentation is now at https://r6.r-lib.org/.

• Fixed #125: The print.R6 method now always returns the object that was passed to it.

• Fixed #155: In some cases, a cloned object's methods could refer to the wrong super object. (#156)

• Fixed #94, #133: When cloning an object which contained a function that is not a method, the corresponding function in the new object would have its environment changed, as though it were a method. Now it no longer has a changed environment. (#156)

• Fixed #121: If a finalize method was present, it would prevent objects passed to initialize from getting GC'd.

• Fixed #158: If a $set method of an R6 generator object is given the value NULL, it previously removed the named item. Now it adds the named item with the value NULL.

• Fixed #159: Printing an R6 object containing a large vector was slow.

R6 2.2.2

• Fixed #108: When an object with a super object and an active binding in the super object was cloned, the new object's super object did not get the active binding -- it was a normal function.

• Fixed #119: When a class had two levels of inheritance, an instance of that class's super object could contain methods that had an incorrect enclosing environment.

R6 2.2.1

• Vignettes now only try use the microbenchmark package if it is present. This is so that the package builds properly on platforms where microbenchmark is not present, like Solaris.

• Fixed ending position for trim().

R6 2.2.0

• Classes can define finalizers explicitly, by defining a public finalize method. (#92, #93)

• Added function is.R6() and is.R6Class(). (#95)

• Fixed #96: R6 now avoids using $ and [[ after the class has been assigned to the object. This allows the user to provide their own methods for $ and [[ without causing problems to R6's operation.

R6 2.1.3

• The plot S3 method for R6 objects will call $plot on the object if present. (#77)

• Fixed printing of members that are R6 objects. (#88)

• Fixed deep cloning for non-portable classes. (#85)

• Added as.list.R6 method. (#91)

R6 2.1.2

• Implemented format.R6() and format.R6ClassGenerator, the former calls a public format method if defined. This might change the functionality of existing classes that define a public format method intended for other purposes (#73. Thanks to Kirill Müller)

• Functions are shown with their interface in print and format, limited to one line (#76. Thanks to Kirill Müller)

• R6 objects and generators print out which class they inherit from. (#67)

R6 2.1.1

• Fixed a bug with printing R6 objects when a [[ method is defined for the class. (#70)

• Fixed cloning of objects that call a super method which accesses private. (#72)

R6 2.1.0

• Added support for making clones of R6 objects with a clone() method on R6 objects. The deep=TRUE option allows for making clones that have copies of fields with reference semantics (like other R6 objects). (#27)

• Allow adding public or private members when there were no public or private members to begin with. (#51)

• Previously, when an R6 object was printed, it accessed (and called) active bindings. Now it simply reports that a field is an active binding. (#37, #38. Thanks to Oscar de Lama)

• Printing private members now works correctly for portable R6 objects. (#26)

• The 'lock' argument has been renamed to 'lock_objects'. Also, there is a new argument, 'lock_class', which can prevent changes to the class. (#52)

• Fixed printing of NULL fields.

R6 2.0.1

• A superclass is validated on object instantation, not on class creation.

• Added debug and undebug methods to generator object.

R6 2.0

• [BREAKING CHANGE] Added portable option, which allows inheritance across different package namespaces, and made it the default.

• Added set() method on class generator object, so new fields and methods can be added after the generator has been created.

• All of the functions involved in instantiating objects are encapsulated in an environment separate from the R6 namespace. This means that if a generator is created with one version of R6, saved, then restored in a new R session that has a different version of R6, there shouldn't be any problems with compatibility.

• Methods are locked so that they can't be changed. (Fixes #19)

• Inheritance of superclasses is dynamic; instead of reading in the superclass when a class is created, this happens each time an object is instantiated. (Fixes #12)

• Added trailing newline when printing R6 objects. (Thanks to Gabor Csardi)

• The print method of R6 objects can be redefined. (Thanks to Gabor Csardi)

R6 1.0.1

• First release on CRAN.

• Removed pryr from suggested packages.

R6 1.0

• First release
