In JohnCoene/echarts4r.assets: Assets for the 'echarts4r' Package

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

All assets currently available.

library(echarts4r)
library(echarts4r.assets)

For demonstration purposes let's create a basic, non working plot to which we'll add assets.

base <- e_charts() %>% # initialise
  e_rm_axis("x") %>% # remove axis
  e_rm_axis("y") 

Examples

These are not all the textures included

base %>% 
  e_globe(
    environment = ea_asset("starfield"),
    base_texture = ea_asset("world night")
  )

base %>% 
  e_globe(
    environment = ea_asset("galaxy"),
    base_texture = ea_asset("jupiter")
  )

base %>% 
  e_globe(
    environment = ea_asset("starfield"),
    base_texture = ea_asset("world topo"),
    height.texture = ea_asset("elevation 4k")
  )

base %>% 
  e_globe(
    environment = ea_asset("starfield"),
    base_texture = ea_asset("world topo"),
    height.texture = ea_asset("elevation 4k"),
    displacementScale = 0.1
  )

base %>% 
  e_globe(
    environment = ea_asset("starfield"),
    base_texture = ea_asset("world"),
    layers = list(
      list(
        type = "overlay",
        shading = "lambert",
        texture = ea_asset("clouds trans"),
        distance = 5
      )
    )
  )

base %>% 
  e_globe(
    displacementScale = 0.1,
    baseColor = "#000",
    shading = "hatching",
    height.texture = ea_asset("elevation 4k"),
    hatchingMaterial = list(
      hatchingTextures = list(
        ea_asset("hatch0"),
        ea_asset("hatch1"),
        ea_asset("hatch2"),
        ea_asset("hatch3"),
        ea_asset("hatch4"),
        ea_asset("hatch5")
      ),
      textureTiling = list(10, 10)
    ),
    postEffect = list(
      enable = TRUE,
      edge = list(
        enable = TRUE
      )
    )
  )

Custom assets

You can use your own assets too of course. In shiny simply place them in your www directory and reference the file name as texture, see the shiny section for more information. In R markdown you can simply use ea_convert to convert your texture.
