check_pheno | R Documentation |
check_pheno Check for the flight curve of a specific year. If the specific year is missing, use the nearest year available within a 5-year period to impute missing count. Function used in impute_count.

)
sp_count_flight |
data.table Object with the flight curve, relative abundance (NM), for a specific year. |
ts_flight_curve |
data.table Object with the all flight curves and relative abundance (NM) for the years available for the search as returned by flight_curve. |
YearCheck |
integer or vector Year to check for nearest flight curve, set internally in impute_count. |
YearLimit |
integer Define the span of years (+/- number of year) to look for a flight curve, if NULL no restriction is set. |
TimeUnit |
character The time-step for which the spline should be computed, 'd' day or 'w' week. |
verbose |
a logical indicating if some “progress report” should be given. |
A data.table with time-series of the expected relative abundance of butterfly count per day (NM) for the year or the nearest year where phenology is available.
