Echarts 5.1.1 has the register_map with the option to choose svg and I’m trying to implement it.

[ghost]

I’m trying to use the new map svg feature of echarts 5.1.1. So, I have manually updated my echarts4r package to the new version. However, I’m missing something when implementing register_map to svg. Like this example: https://echarts.apache.org/examples/en/editor.html?c=geo-beef-cuts

So I trying to implant this way:
The Echarts js code:

 echarts.registerMap('Beef_cuts_France', { svg });

The equivalent in R:

svg='https://echarts.apache.org/examples/data/asset/geo/Beef_cuts_France.svg'
q$x$registerMap[[1]] = list(mapName="USA", list(svg))

As you can se the equivalent would use a named and an unnamed list, and R doesn’t allow that.
Any Idea of what could help?

Complete code:

library(echarts4r)
svg='https://echarts.apache.org/examples/data/asset/geo/Beef_cuts_France.svg'

q=data %>% 
  e_charts() %>% 
  e_map_register("USA", json= json) %>%
  e_map(value, map = "USA")

q$x$registerMap[[1]] = list(mapName="USA", list(svg))
q

Thank you

Pretty neat, I did not know this was added. Reinstall the latest version and use the new e_svg function. I have put this example here

url <- "https://echarts.apache.org/examples/data/asset/geo/Beef_cuts_France.svg"

svg <- url %>% 
  readLines() %>% 
  paste0(collapse = "")

data <- tibble::tibble(
  name = c(
    "Queue", 
    "Langue",
    "Plat de joue",
    "Collier",
    "Rumsteck"
  ),
  value = runif(5, 10, 15)
)

data %>% 
  e_charts(name) %>% 
  e_svg_register("beef", svg) %>% 
  e_svg(
    value,
    map = "beef",
    label = list(
      show = FALSE
    )
  ) %>% 
  e_visual_map(value)

I have installed the latest version, using install_github(). But it returns an error
“Error in e_svg(., value, map = "beef", label = list(show = FALSE)) :
could not find function "e_svg" “. Maybe the server has not updated yet.

It should work after restarting the R session.

1. Install
2. Restart R/session
3. Try again
