Tests two objects for complete equality. Operations on objects that really leave everything alone (for example, adding 0 to numeric objects) should retain
identity, but no allowance is made for rounding error, trailing blank characters,
etc. Objects of different class are not identical even if their contents are otherwise
the same.
USAGE:
identical
(
object1
,
object2
)
REQUIRED ARGUMENTS:
object1
Any S-PLUS object.
object2
Any S-PLUS object.
VALUE:
Logical value. Returns
TRUE if the two objects are exactly equal in all respects,
FALSE otherwise.

EXAMPLES:
x <- 1
y <- x + 0.000000001
all.equal(x, y) # returns T
identical(x, y) # returns F
