| classVersion {Biobase} | R Documentation |
These generic functions return version information for classes
derived from Versioned-class, or
VersionsNull-class for unversioned objects. The
version information is an object of Versions-class.
By default, classVersion has the following behaviors:
classVersion(Versioned-instance)Versions-class object obtaine from the object.classVersion{"class"}class and return the current version information, if available.classVersion(ANY)VersionsNull-class object to indicate no version information available.
By default, the classVersion<- method has the following behavior:
classVersion(Versioned-instance)["id"] <- valuevalue to Versions-instance. value is coerced to a valid version description. see Versions-class for additional access methods.classVersion(object) classVersion(object) <- value
