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 = "end", 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 number of values to consider.

ignore_truncation

A flag specifying whether to ignore truncation of the mean daily water temperature vector or a string of "start", "end", "none" (equivalent to FALSE) or "both" (equivalent to TRUE) specifying which type of truncation to ignore.

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.
