plot_frequency: Plot distribution of inputed lake levels

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

Description

Given a data frame with lake levels for a single lake or multiple lakes, plot the distribution (density) of estimated lake levels. If data frame has multiple lakes, will display as facet plots. Options to add xintercepts.

Usage

plot_frequency(
  df,
  convert_to_ft = TRUE,
  xintercept = NULL,
  probs = NULL,
  title = "",
  text_size = 12,
  vline_color = "#c00000",
  hist_color = "grey80",
  density_color = "#c00000",
  line_size = 1,
  pfl_is_long = TRUE,
  labels = TRUE,
  lakes = c("Pleasant", "Long", "Plainfield")
)

Arguments

df	a data frame with columns for "lake", "date", "level_obs", and "level_pred".
convert_to_ft	defaults to TRUE to convert lake levels from meters to ft
xintercept	either a single value (if only one lake) or a data frame with two columns: "xintercept" with the values, and "lake" with the name of each lake in df. Default to NULL to not add a line.
probs	exceedance probabilities (e.g., 10 for 10%) to identify with a horizontal line
title	string to use for title of plot, defaults to "".
text_size	size of text, defaults to 12
vline_color	color of vertical line, defaults to a red ("#c00000")
hist_color	color of histogram bins, defaults to "grey80"
density_color	color of density curve with alpha = 0.2, defaults to a red ("#c00000")
line_size	line size, default to 1
pfl_is_long	defaults to TRUE to force the y-limits of plainfield lake to the same as long lake.
labels	logical defaults to TRUE to label exceedance probabilities (if displayed)
lakes	vector of lakes to include in plot. Defaults to c("Pleasant", "Long", "Plainfield")

Value

plot_obj, a plot with the distribution(s) of estimated lake elevation
