Interactive Hex Map — hex_browse • hexify

Opens an interactive leaflet map with hexagonal cell polygons. Cells can be colored by a data column, with popups showing cell information on click.

Usage

hex_browse(
  hex_data,
  grid = NULL,
  value = NULL,
  palette = "viridis",
  opacity = 0.7
)

Arguments

hex_data: A HexData object, or a data.frame with a cell_id column.
grid: A HexGridInfo object. Required if hex_data is a data.frame.
value: Optional column name (character) to color cells by. If NULL, cells are colored uniformly.
palette: Color palette name for continuous values. Default "viridis".
opacity: Fill opacity (0-1). Default 0.7.

Value

A leaflet map object (can be printed or embedded in Shiny).

Details

Requires the leaflet package (in Suggests). The map is built using as_sf() to generate polygon geometries, then rendered as a leaflet choropleth.

# \donttest{
if (requireNamespace("leaflet", quietly = TRUE)) {
  df <- data.frame(
    lon = runif(50, -5, 5),
    lat = runif(50, 45, 55),
    value = rnorm(50)
  )
  hd <- hexify(df, lon = "lon", lat = "lat", area_km2 = 500)
  hex_browse(hd, value = "value")
}
