Converts boat-count rows plus mean anglers-per-boat inputs into canonical
sampled-day effort rows for downstream use with add_counts(). This helper
is intentionally narrow: it handles the common boat-party expansion
(boat_count * mean_party_size) and leaves broader source-specific
reconstruction outside estimator internals.
The returned table always contains canonical columns:
date, any selected strata columns, effort_type, daily_effort, psu,
and correction_factor. Optional columns n_counts, within_day_var, and
source_method are included when supplied.
Usage
prep_counts_boat_party(
data,
date,
strata = NULL,
boat_count,
mean_party_size,
effort_type = "boat",
correction_factor = 1,
psu = NULL,
n_counts = NULL,
within_day_var = NULL,
source_method = "boat_count_x_mean_party_size"
)Arguments
- data
A data frame containing sampled-day boat-count rows.
- date
Tidy selector for the Date column.
- strata
Optional tidy selector for one or more strata columns.
- boat_count
Tidy selector for the numeric boat count column.
- mean_party_size
Tidy selector for the numeric mean anglers-per-boat column.
- effort_type
Effort-type values for output. Defaults to "boat". May be a scalar string/factor or an expression that evaluates to one value per row.
- correction_factor
Optional multiplicative correction applied after the boat-party expansion. May be a scalar (defaults to
1) or an expression that evaluates to a numeric vector with one value per row. Values must be finite and strictly positive.- psu
Optional tidy selector for the PSU column. Defaults to the selected date column when omitted.
- n_counts
Optional tidy selector for the number of within-day counts used to compute the sampled-day estimate.
- within_day_var
Optional tidy selector for a within-day variance or sum of squares column associated with the sampled-day estimate.
- source_method
Optional source-method values. Defaults to
"boat_count_x_mean_party_size". May be a scalar string/factor or an expression that evaluates to one value per row.
Value
A tibble with canonical sampled-day effort columns. Required columns
are date, selected strata columns (if any), effort_type, daily_effort,
psu, and correction_factor. Optional columns are appended when supplied.
