Changes in version 1.0-21

• Vectorize all [cg]set predicates and check for correct arguments

• add as.vector() methods for [cg]sets

• rename element class to gset_element to avoid name clash with ggplot

Changes in version 1.0-20

• Some small fixes in interval code

• [gc]set_complement(a, b) now use the union of the universes of a and b, and the max. bound of a and b if no global defaults are specified.

Changes in version 1.0-19

• no user-level changes

Changes in version 1.0-18

• Do not export as.list.function() any more

Changes in version 1.0-17

• add lengths method

• the extract operator ([[) now returns NULL if the requested element can not be found instead of throwing a cryptical error message

• some small internal optimizations

Changes in version 1.0-16

• no user-level changes

Changes in version 1.0-15

• add import statements for functions in recommended packages to ‘NAMESPACE’

Changes in version 1.0-14

• internal fix because nchar(NA) now returns NA

Changes in version 1.0-13

• Rd improvements

Changes in version 1.0-12

• small fix in LABELS() (when called with NULL)

Changes in version 1.0-11

• Author/Maintainer info removed from DESCRIPTION

Changes in version 1.0-10

• The length() methods for [cg]sets are no longer aliases for gset_cardinality(), but for set_cardinality() (i.e., give the number of elements in the [cg]set). This change has been made since length() methods are expected to yield integer values only.

Changes in version 1.0-9

• small bug fix in fuzzy_two_normals()

Changes in version 1.0-8

• Package news converted to Rd format.

Changes in version 1.0-7

• small fix in interval code

Changes in version 1.0-6

• small fix in all.equal() method

Changes in version 1.0-5

• bug fix in all.equal() method

• overloaded set operators will now work for operands of mixed set types

Changes in version 1.0-4

• as.list.interval() now returns a list of intervals instead of just applying unclass()

Changes in version 1.0-3

• small bug fixes

Changes in version 1.0-2

• small bug fixes

Changes in version 1.0-1

• interval class for possibly infinite numeric intervals added.

• fuzzy rules now accept the use of brackets in the expressions.

• Missing memberships are now supported.

Changes in version 1.0

• JSS article as vignette added.

• fuzzy_pi4() generator added.

• [gc]set_memberships extended to allow for filter elements and to work with tuples.

Changes in version 0.7

• L1 and L2 dissimilarities for fuzzy multisets added.

• fuzzy_pi() generator added

• (fuzzy) multisets are now n-bounded (where n is the maximal multiplicity). This now allows consistent complement-building.

• nu-cuts added (filters elements according to multiplicity).

Changes in version 0.6

• fuzzy inference framework added

• converters for matrices added

Changes in version 0.5

• bug fixes in ordering function and as.character.cset()

Changes in version 0.2

• A lot of bug fixes

• closure and reduction of sets added
