Plot metal concentrations against aluminum

Description

Plot metal concentrations against aluminum

Usage

show_sedimentalratio(
  sedimentdata,
  param,
  yrrng = c(1993, 2023),
  bay_segment = c("HB", "OTB", "MTB", "LTB", "TCB", "MR", "BCB"),
  funding_proj = "TBEP",
  lnsz = 1,
  base_size = 12,
  plotly = FALSE,
  family = NA,
  width = NULL,
  height = NULL
)

Arguments

sedimentdata	input sediment data.frame as returned by read_importsediment
param	chr string for which parameter to plot, must be a metal
yrrng	numeric vector indicating min, max years to include, use single year for one year of data
bay_segment	chr string for the bay segment, one to many of "HB", "OTB", "MTB", "LTB", "TCB", "MR", "BCB"
funding_proj	chr string for the funding project, one to many of "TBEP" (default), "TBEP-Special", "Apollo Beach", "Janicki Contract", "Rivers", "Tidal Streams"
lnsz	numeric for line size
base_size	numeric indicating text scaling size for plot
plotly	logical if matrix is created using plotly
family	optional chr string indicating font family for text labels
width	numeric for width of the plot in pixels, only applies of plotly = TRUE
height	numeric for height of the plot in pixels, only applies of plotly = TRUE

Details

The plot shows the selected contaminant concentration relative to aluminum, the latter being present as a common metal in the Earth's crust. An elevated ratio of a metal parameter relative to aluminum suggests it is higher than background concentrations.

Lines for the Threshold Effect Level (TEL) and Potential Effect Level (PEL) are shown for the parameter, if available.

Value

A ggplot object or a plotly object if plotly = TRUE showing the ratio of the selected parameter plotted against aluminum concentrations collected at the same site. Black lines show the linear fit of a log-log model and the 95% prediction intervals.
