Interactive map of Close spatial results — close

Draw the sf object a client method returns as an interactive map on a CARTO Positron basemap. Points (POIs, places) render as bright hoverable markers; polygons (census blocks) are filled, optionally greying the features that do not meet a criterion so the ones that matter stand out. The view auto-zooms to fit every layer with a margin, and hover shows all attributes.

Usage

close_map(
  x,
  color = "#e8590c",
  highlight = NULL,
  fill = NULL,
  palette = "YlGnBu",
  reverse = FALSE,
  label = NULL,
  size = 15,
  opacity = 0.65,
  boundary = NULL,
  background = NULL,
  background_color = "#3b6fb0",
  background_opacity = 0.3,
  background_fill = TRUE,
  points = NULL,
  points_color = "#e8590c",
  mark = NULL,
  buffer = 0.15,
  zoom = NULL
)

Arguments

x: An sf from a client method: points or polygons.
color: Marker/fill colour for flat features (or for highlighted ones).
highlight: Optional. A logical vector (length nrow(x)) or the name of a logical/0-1 column in x. When supplied, features that do not meet it render grey (#888) and the rest use color, so you can show every block in a study area and pick out the matches, rather than dropping the others.
fill: Optional. The name of a numeric column to shade features by, on a continuous ColorBrewer scale with a legend (e.g. travel time, or an access score). Use this OR highlight, not both.
palette: A plotly ColorBrewer colorscale name for fill (default "YlGnBu").
reverse: Which end of the YlGnBu scale is blue. FALSE (default) puts blue at the low values, TRUE at the high values. Choose so blue marks the most-accessible end: FALSE for travel time (low is best), TRUE for a score.
label: Optional. A column shown first (bold) in the hover; the rest of the attributes follow.
size: Marker size, for point maps.
opacity: Fill opacity, for polygon maps.
boundary: Optional. A polygon sf drawn as a grey outline underneath the data, e.g. a city boundary from place_boundary().
background: Optional. A polygon sf, or a list of them, drawn as semi-transparent fills underneath the data, e.g. commute isochrones, or a walkshed under its POIs.
background_color: Fill colour(s) for background, recycled across the layers.
background_opacity: Fill opacity for background layers.
background_fill: Fill the background layers (default TRUE); FALSE draws them as outlines only.
points: Optional. A point sf drawn as markers on top of the main layer, e.g. POI locations over a block map.
points_color: Marker colour for points.
mark: Optional. A point to mark on top with an X, either a c(lon, lat) pair or a point sf/sfc (e.g. a starting point).
buffer: Fraction of the data extent to pad the view by (default 0.15).
zoom: Deprecated/ignored; the view auto-zooms to the data.

Value

A plotly map object.

Examples

if (FALSE) { # \dontrun{
close <- close_client()
close_map(close$place_pois(geoid = "4459000", type = 30), color = "#e8590c")
