In WDNR-Water-Use/CSLSscenarios: CSLS MODFLOW Scenario Analysis

Description

Given a data frame with a "lake", "date", and "level" columns as well as a vector of desired lag (e.g., 1 month, 3 months, 12 months), calculates the change in lake levels over each time period.

Usage

calculate_rates(df, months = c(1, 3, 12))

Arguments

df	a data frame with a "lake" and a "level" column
months	a vector with all lag times (in months) to consider, defaults to c(1, 3, 12).
