Enforce Specific Structure for R Objects

Description

These routines are useful when preparing to pass objects to a Spark routine, as it is often necessary to ensure certain parameters are scalar integers, or scalar doubles, and so on.

Arguments

`object`	An R object.
`allow.na`	Are `NA` values permitted for this object?
`allow.null`	Are `NULL` values permitted for this object?
`default`	If `object` is `NULL`, what value should be used in its place? If `default` is specified, `allow.null` is ignored (and assumed to be `TRUE`).
