Calculate the estimated egg emergence timing based on cumulative degree-days of water temperature time-series data

Description

Calculate the estimated egg emergence timing based on cumulative degree-days of water temperature time-series data

Usage

calcEmergenceTiming(
  tout,
  atu.day = 263,
  davg = T,
  interpMissing = T,
  hatchValue = 1750
)

Arguments

tout	dataframe; tout is a dataframe with the first column as a numeric Julian day
atu.day	numeric; the day in which to start the emergence calculation, default = 263
davg	logical; calculate based on daily average, default = TRUE
interpMissing	logical, interpolate missing values? Default = TRUE
hatchValue	numeric, the value in which eggs are assumed to hatch. Defaults to 1750

Value

atu.d	a dataframe with numeric JDAY dates
atu	a dataframe with month and day units for the date
