Counts the number of interviews for each fishing method within each calendar
month. Method is taken from the column set via
add_interviews(angler_method = ...).
Value
A data.frame with class c("creel_summary_method",
"data.frame") and columns: month, method, N,
percent.
Details
Interview-based summary, not pressure-weighted. This function
tabulates raw interview records without applying survey weighting by sampling
effort or effort stratum. For pressure-weighted extrapolated estimates, use
estimate_catch_rate or estimate_harvest_rate.
