Create a new bimap

Instantiates a new bimap object, i.e. an unordered collection of key-value pairs with mappings $$f: keys -> values,$$ and $$f: values -> keys.$$

bimap(key.class = c("character", "numeric", "integer"),
  value.class = c("character", "numeric", "integer"))

Arguments

key.class	the primitive class type of the keys
value.class	the primitive class type of the values

Value

returns a new bimap object

Examples

 # create a bimap with character <-> character bi-mapping
 b <- bimap()

 # create a bimap with character <-> integer bi-mapping
 b <- bimap("character", "integer")

 # create a bimap with integer <-> integer bi-mapping
 b <- bimap("integer", "numeric")
