d3_method: Calculate D3 Method for Snow Loads

In Kinekenneth48/rdailychange: Daily Change Method for Spatial Data

Description

Given a dataframe, a column of which includes snow observations, this function will calculate the D3 Method.

Usage

d3_method(df, col_name = "SWE")

Arguments

df	The dataframe containing snow observations.
col_name	Character string of the column name containing the snow observations.

Value

A list of numeric vectors containing the observations for the D3 Method (list split across 2 or more raw observations of 0).

Examples

ID <- rep("USW00023062", 13)
NAME <- rep("DENVER-STAPLETON", 13)
STATE <- rep("CO", 13)
