Enforce Specific Structure for R Objects




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 Description
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).
