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
