is(7,"integer")]:
As for the question of the bug in "is", ... "it depends what your
definition of `is' is." [Bill Clinton]

As for the question of the bug in "is" - although I hate to sound like
a politician who was given the nickname "Slick Willie" (see Clinton,
William J.), "it depends what your definition of `is' is." The
definition in R is a function that examines the class of an object and
reports on whether the object has the given class or is of a class
that inherits from the given class. In this case it will give an
answer based on the class of the computer representation of the
number, not the mathematical concept of the number.
