Add points from tabular longitude and latitude columns

Usage

add_xy_data(
  map,
  data,
  x = "longitude",
  y = "latitude",
  name = "XY Data",
  style = list(),
  visible = TRUE,
  opacity = 1,
  ...
)

Arguments

map: A GeoLibre widget.
data: A data frame, a CSV file path, a CSV URL, CSV text, or a list of row lists.
x: Name of the longitude column.
y: Name of the latitude column.
name: Layer name.
style: Named list of GeoLibre style overrides such as fillColor, strokeColor, and strokeWidth.
visible: Whether the layer is initially visible.
opacity: Layer opacity from zero to one.
...: Additional style overrides given as named arguments, merged into style. add_geojson(map, data, fillColor = "red") and add_geojson(map, data, style = list(fillColor = "red")) are equivalent.

Value

The modified widget.

cities <- data.frame(
  name = c("Washington", "New York"),
  longitude = c(-77.0369, -74.006),
  latitude = c(38.9072, 40.7128)
)
map <- geolibre() |> add_xy_data(cities, name = "Cities")
stopifnot(length(map$x$project$layers[[1]]$geojson$features) == 2L)
