R中的Mapdeck程序包-add_grid似乎不呈现任何内容 [英] Mapdeck Package in R - add_grid Does Not Appear to Render Anything

问题描述

问题:

R mapdeck包中的add_grid函数非常令人兴奋.但是，按照 CRAN文档，我似乎无法获得实际在返回的地图上绘制的任何数据.

The add_grid function in the R mapdeck package is very exciting. However, following the CRAN documentation, I cannot seem to get any data to actually plot on the returned map.

换句话说，地图返回了，但是没有绘制数据.这是一个已知的错误吗?

In other words, the map returns, but no data is plotted. Is this a known bug?

代码:

library(tidyverse)
library(mapdeck)

# - Enter mapdeck key ... Note that it is user-specific
key <- rstudioapi::askForPassword() 

# - Read Example Data Set
df <- read.csv(paste0(
  'https://raw.githubusercontent.com/uber-common/deck.gl-data/master/',
  'examples/3d-heatmap/heatmap-data.csv'
))

# - Plot Data ... Note how the map returns, but not the data
mapdeck( token = key, style = 'mapbox://styles/mapbox/dark-v9', pitch = 45 ) %>%
  add_grid(
    data = df
    , lat = "lat"
    , lon = "lng"
    , cell_size = 5000
    , elevation_scale = 50
    , layer_id = "grid_layer"
  )

推荐答案

这不一定是mapdeck本身内部的错误"，而是mapdeck与RStudio进行通信的方式.他们使用的不同javascript版本之间存在冲突.

This is not necessarily a 'bug' inside mapdeck itself, but more the way mapdeck communicates with RStudio. There are conflicts between the different javascript versions they use.

如果您在浏览器中打开该图(通过按Rstudio中的在新窗口中显示按钮)，则应该获取该图.

If you open the plot in a browser (by pressing the show in new window button in Rstudio) you should get your plot.

我遇到了这个问题已记录，但不知道方法前进呢.

I've got this issue logged, but don't know the way forward yet.
