Value

An HTML widget object (leaflet map) that can be printed or displayed in R Markdown or Shiny applications.

Arguments

data

A data frame containing station coordinates and names. The function accepts either:

• Standard format: station_name, sample_longitude_dd, sample_latitude_dd

• Delivery format: STATN, LONGI, LATIT

provider

Character. The tile provider to use for the map background. See available providers at https://leaflet-extras.github.io/leaflet-providers/preview/. Defaults to "CartoDB.Positron".

Examples

# Example data
df <- data.frame(
  station_name = c("Station A", "Station B"),
  sample_longitude_dd = c(10.0, 10.5),
  sample_latitude_dd = c(59.0, 59.5)
)

# Plot points on map
map <- plot_map_leaflet(df)

# Example data in SHARK delivery format
df_deliv <- data.frame(
  STATN = c("Station A", "Station B"),
  LONGI = c(10.0, 10.5),
  LATIT = c(59.0, 59.5)
)

# Plot points on map
map_deliv <- plot_map_leaflet(df_deliv)
