Plot monthly chlorophyll or light attenuation values for a segment

Description

Plot monthly chlorophyll or light attenuation values for a bay segment

Usage

show_boxplot(
  epcdata,
  param = c("chla", "la"),
  yrsel = NULL,
  yrrng = c(1975, 2024),
  ptsz = 0.5,
  bay_segment = c("OTB", "HB", "MTB", "LTB"),
  trgs = NULL,
  family = NA,
  labelexp = TRUE,
  txtlab = TRUE,
  partialyr = FALSE,
  points = TRUE
)

Arguments

epcdata	data frame of epc data returned by read_importwq
param	chr string for which parameter to plot, one of "chla" for chlorophyll or "la" for light attenuation
yrsel	numeric for year to emphasize, shown as separate red points on the plot
yrrng	numeric vector indicating min, max years to include
ptsz	numeric indicating point size of observations not in yrsel
bay_segment	chr string for the bay segment, one of "OTB", "HB", "MTB", "LTB"
trgs	optional data.frame for annual bay segment water quality targets, defaults to targets
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
partialyr	logical indicating if incomplete annual data for the most recent year are approximated by five year monthly averages for each parameter
points	logical indicating if jittered point observations, including outliers, are shown in the plot

Details

Points not included in yrsel are plotted over the box plots using position_jitter. Use ptsz = -1 to suppress. The dotted line in the plot shows the large exceedance value.

Value

A ggplot object

Examples

show_boxplot(epcdata, bay_segment = 'OTB')
