Build a days dataset by summarising palmsplus
by day and person (identifier). Not all variables in palmsplus
are summarised, only those specified using palms_add_field with
the argument domain_field = TRUE. By default, a duration field
is added (e.g., the total minutes per day).
All data are summarised by default. However, additional aggragation domains
can be specified using palms_add_domain before building days.
Domains are a subset of data, such as during school time. All domain_field
variables will be summarised for each domain seperatly.
