Creates or tests for objects of type "integer".
integer(length = 0)
as.integer(x, ...)
is.integer(x)

desired length. |
x |
object to be coerced or tested. |

further arguments passed to or from other methods. |
integer creates a integer vector of the specified length.
Each element of the vector is equal to 0.
Integer vectors exist so that data can be passed to C or Fortran code
which expects them.
as.integer attempts to coerce its argument to be of integer
type. The answer will be NA unless the coercion succeeds.
Real values larger in modulus than the largest integer are coerced to
NA (unlike S which gives the most extreme integer of the same sign).
is.integer returns TRUE or FALSE depending on
whether its argument is of integer type or not.
