Arguments

Methods

The following are defined; package developers may write additional methods.
new("Versions", ...)
Create a new Versions-class instance, perhaps with named version elements (the contents of ...) added. Named elements of versions are character strings that can be coerced using package_version, or package_version instances, Versions-class objects.
object["id"]
Obtain version information "id" from object.
object["id"] <- value
Create or update version information "id" on instance object.
object[["id"]]
Obtain version information "id" from object. The result is a list of integers, corresponding to entries in the version string.
object[["id"]] <- value
Create or update version information "id" on instance object.
object$id
Obtain version information "id" from object.The result is a list of integers, corresponding to entries in the version string.
object$id <- value
Create or update version information "id" on instance object.
show(object)
Display version information.
updateObject(object)
Update object to the current Versions-class representation. Note that this does not update another class that uses Versions-class to track the class version.
as(object, "character")
Convert object to character representation, e.g., 1.0.0
object1 < object2
Compare object1 and object2 using version class information. Symbols in addition to < are admissible; see ?Ops
