Plot annual water quality values, targets, and thresholds for a segment

Plot annual water quality values, targets, and thresholds for a bay segment

Usage

show_thrplot(
  epcdata,
  bay_segment = c("OTB", "HB", "MTB", "LTB"),
  thr = c("chla", "la"),
  trgs = NULL,
  yrrng = c(1975, 2023),
  family = NA,
  labelexp = TRUE,
  txtlab = TRUE,
  thrs = FALSE,
  partialyr = FALSE
)

Arguments

epcdata

data frame of epc data returned by read_importwq

bay_segment

chr string for the bay segment, one of "OTB", "HB", "MTB", "LTB"

thr

chr string indicating which water quality value and appropriate target/threshold to plot, one of "chl" for chlorophyll and "la" for light availability

trgs

optional data.frame for annual bay segment water quality targets/thresholds, defaults to targets

yrrng

numeric vector indicating min, max years to include

family

optional chr string indicating font family for text labels

labelexp

logical indicating if y axis and target labels are plotted as expressions, default TRUE

txtlab

logical indicating if a text label for the target value is shown in the plot

thrs

logical indicating if reference lines are shown only for the regulatory threshold

partialyr

logical indicating if incomplete annual data for the most recent year are approximated by five year monthly averages for each parameter

Value

A ggplot object

Examples

show_thrplot(epcdata, bay_segment = 'OTB', thr = 'chl')
