else_do

Creates an ELSE rule for use inside data_step().

Provides 'SAS'-style IF/ELSE chains, independent IF rules,
and DELETE logic for 'data.table', enabling clinical programmers to
express Study Data Tabulation Model (SDTM) and Analysis Data Model
(ADaM)-style derivations in familiar SAS-like syntax.
Methods are informed by clinical data standards described in CDISC
SDTM and ADaM implementation guides. See
<https://www.cdisc.org/standards/foundational/sdtm> and
<https://www.cdisc.org/standards/foundational/adam>.
