Create Map Symbols for 'leaflet' maps

Description

Create Map Symbols for 'leaflet' maps

Usage

makeSymbol(
  shape,
  width,
  height = width,
  color,
  fillColor = color,
  opacity = 1,
  fillOpacity = opacity,
  ...
)

makeSvgUri(svg, width, height, strokeWidth)

makeSymbolIcons(
  shape,
  color,
  fillColor = color,
  opacity,
  fillOpacity = opacity,
  strokeWidth = 1,
  width,
  height = width,
  ...
)

addSymbols(
  map,
  lng,
  lat,
  values,
  shape,
  color,
  fillColor = color,
  opacity = 1,
  fillOpacity = opacity,
  strokeWidth = 1,
  width = 20,
  height = width,
  dashArray = NULL,
  data = leaflet::getMapData(map),
  ...
)

addSymbolsSize(
  map,
  lng,
  lat,
  values,
  shape,
  color,
  fillColor = color,
  opacity = 1,
  fillOpacity = opacity,
  strokeWidth = 1,
  baseSize = 20,
  data = leaflet::getMapData(map),
  ...
)

sizeNumeric(values, baseSize)

sizeBreaks(values, breaks, baseSize, ...)

makeSymbolsSize(
  values,
  shape = "rect",
  color,
  fillColor,
  opacity = 1,
  fillOpacity = opacity,
  strokeWidth = 1,
  baseSize,
  ...
)

Arguments

shape

the desired shape of the symbol, See availableShapes

width

in pixels

height

in pixels

color

stroke color

fillColor

fill color

opacity

stroke opacity

fillOpacity

fill opacity

...

arguments to pass to pretty

svg

inner svg tags for symbol

strokeWidth

stroke width in pixels

map

a map widget object created from 'leaflet'

lng

a numeric vector of longitudes, or a one-sided formula of the form ~x where x is a variable in data; by default (if not explicitly provided), it will be automatically inferred from data by looking for a column named lng, long, or longitude (case-insensitively)

lat

a vector of latitudes or a formula (similar to the lng argument; the names lat and latitude are used when guessing the latitude column from data)

values

the values used to generate shapes; can be omitted for a single type of shape

dashArray

a string or vector/list of strings that defines the stroke dash pattern

data

the data object from which the argument values are derived; by default, it is the data object provided to leaflet() initially, but can be overridden

baseSize

re-scaling size in pixels of the mean of the values, the average value will be this exact size

breaks

an integer specifying the number of breaks or a numeric vector of the breaks; if a named vector then the names are used as labels.

Value

HTML svg element
