classes_ordered

expect_classes_ordered

any object which may or may not have classes from this package

The order of classes can matter because, for some functions, we'd prefer to
decide what to do based on a higher level structure, e.g. whether the
structure is a comorbidity map before caring if it is ICD-9 or ICD-10. I
can't see how it matters whether we prioritize long/wide and short/decimal
yet, so won't test.

Calculate comorbidities, Charlson and van Walraven
scores, perform fast and accurate validation, conversion,
manipulation, filtering and comparison of ICD-9 and ICD-10 codes. This
package enables a work flow from raw lists of ICD codes in hospital
databases to comorbidities.  ICD-9 and ICD-10 comorbidity mappings
from Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ
included.  Common ambiguities and code formats are handled.
