This function creates a then list object which restricts the time constraint of a segment to be added to a sequence segment.
seg_then(limit = "within", count = 1, unit = "year")
The limitation of the restriction. Either
within (default) or
How many of the units should be used.
1 is set as default.
A unit of time. Valid values are
year. Always use the singular form.
a structured list of time restrictions to be used to build the sequential segment
In the UI you can add 'after' and 'within' statements to create a more complex time restriction.
The same can be accomplished using this function by listing the limits, counts, and units in a c()
function. This would look like:
limit = c('within', 'after'), count = c(5, 1), unit = c('hit', 'visit')
Time restrictions can only be combined using 'within' first before 'after'. The function will automatically align these to be in the correct list item order.
