Creates an area plot of groundwater levels with trend line

Description

An area plot (hydrograph) of groundwater levels, with trend line of a given slope and intercept, optionally with interpolated values shown.

Usage

gwl_area_plot(dataframe, trend, intercept, trend_category, sig,
  showInterpolated = FALSE, show_stable_line = FALSE, save = FALSE,
  path = "./", mkperiod = "annual", opts = NULL)

Arguments

dataframe	A dataframe with well level monthly time series and the following columns: Date, med_GWL, nReadings
trend	(Numeric) Trend in m/month
intercept	(Numeric) Intercept in m
trend_category	Trend category: "stable", or another description of the magnitude and direction of the trend. This description will be displayed on the graph in Title Case. If "stable", no trend value or statistical significance will be displayed on the plot, otherwise trend value will be displayed alongside the category information.
sig	(Numeric) Significance of trend test
showInterpolated	(Logical) Show the points where missing values in the time series were interpolated
show_stable_line	(Logical) Show the Mann-Kendall trend line when category is "stable"
save	Save the graph to file?
path	Where to save the graph if save = TRUE
mkperiod	The period ("monthly" or "annual") the Mann-Kendall test was performed on
opts	Other options to pass to ggplot2
