Map water quality data for a selected year

Usage

show_sitemappep(
  dat,
  yrsel = NULL,
  mosel = NULL,
  param = c("chla", "sd", "tn"),
  bay_segment = c("1a", "1b", "2", "3"),
  maxrel = 0.99,
  relative = FALSE
)

Arguments

dat: data frame of data returned by read_pepwq
yrsel: numeric for years to plot, see details
mosel: numeric for months to plot, see details
param: chr string indicating which water quality value to plot, one of "chla" for chlorophyll, "sd" for secchi depth, or "tn" for total nitrogen
bay_segment: chr string for the bay segment, one or all of "1a", "1b", "2", or "3"
maxrel: numeric for the maximum quantile value for scaling if relative = T, this prevents outliers from skewing the scale
relative: logical indicating if sizes and colors are relative to the entire water quality data base, otherwise scaling is relative only for the points on the map

Value

A leaflet object

Details

Year estimates for the selected parameter are based on median observations across months. All twelve months are used if mosel = NULL (default). Monthly estimates for the selected parameter are based on median observations across years. All years are used if yrsel = NULL (default).

The color ramp and size scaling of points are reversed for Secchi observations.

Examples


# 2018, all months
show_sitemappep(rawdat, yrsel = 2018)


# 2018, July only
show_sitemappep(rawdat, yrsel = 2018, mosel = 7)


# July only, all years
show_sitemappep(rawdat, mosel = 7)
