Calculate Growing Seasons (GSS)

Source: R/gss.R
gss.Rd

A wrapper on gsdd::gss() to by default get all Growing Seasons ignoring truncation. For more information see gsdd::gss().

Usage

gss(x, min_length = 120, ignore_truncation = TRUE, pick = "all", msgs = TRUE)

Arguments

x

A data frame with two columns date and temperature. date, which must be of class Date provides the dates and temperature which must be a numeric vector provides the mean daily water temperature in degrees centigrade.

min_length

A whole number of the minimum length to consider. Must be at least twice the window width but no more than 365. If NULL then set to be the difference between start_date and end_date (ignoring the year).

ignore_truncation

A flag specifying whether to ignore start truncation (end truncation is always ignored).

pick

A string specifying whether to pick the "longest", "shortest", "first" or "last" 'season' or the season with the "biggest" or "smallest" GSDD. By default the returned value is the the GSDD value for the "longest" 'season'.

msgs

A flag specifying whether to provide messages.
