calculate_exceedances: Calculate exceedance levels

In WDNR-Water-Use/CSLSlevels: CSLS Lake Level Analysis

Description

Given a data frame with a "lake" and "level" column, calculates levels associated with desired exceedance probabilities.

Usage

calculate_exceedances(
  df,
  probs = c(10, 25, 50, 75, 90),
  departures = NULL,
  melted = TRUE
)

Arguments

df	a data frame with a "lake" and a "level" column
probs	a vector with all exceedance probabilities to calculate. Defaults to c(10, 25, 50, 75, 90)
departures	optional vector with departures from median to evaluate probability of occurrence. Defaults to NULL to trigger exceedance probability calculations instead.
melted	logical defaults to true to indicate should melt data frame to just 3 columns (lake, variable, value). Otherwise, keeps as data frame with one column per exceedance probability.

Value

exceeds, a data frame with the names of all lakes and corresponding exceedance levels
