Display the object, by printing, plotting or whatever suits its
class. This function exists to be specialized by methods. The
default method calls showDefault.
Formal methods for show will
usually be invoked for automatic printing (see the details).
# S4 method for DatabaseConnectorDriver
show(object)show returns an invisible NULL.
Any R object
Objects from an S4 class (a class defined by a call to
setClass) will be displayed automatically is if by a
call to show. S4 objects that occur as attributes of S3
objects will also be displayed in this form; conversely, S3 objects
encountered as slots in S4 objects will be printed using the S3
convention, as if by a call to print.
Methods defined for show will only be inherited by simple
inheritance, since otherwise the method would not receive the
complete, original object, with misleading results. See the
simpleInheritanceOnly argument to setGeneric and
the discussion in setIs for the general concept.
showMethods prints all the methods for one or more
functions.
