ggmap自定义地图样式 [英] Custom map style with ggmap

问题描述

我已使用 https://mapstyle.withgoogle.com/自定义了供ggmap使用的样式.一个>.我的问题是如何将JSON集成到我的R代码中.

I have customized a style for use with ggmap using https://mapstyle.withgoogle.com/. My question is how to integrate the JSON into my R code.

我尝试了以下代码，但无济于事:

I tried the following code to no avail:

map <- get_googlemap(center = 'London', zoom = 15, 
                     style = c('element:labels|visibility:off', 'feature:road.local|visibility:off'))
ggmap(map)

它可以单独使用任何一种样式命令，但不能一起使用.我的代码中的错误在哪里?

It works with either of the style commands alone but not together. Where is the bug in my code?

推荐答案

我已经开发了一个软件包ggmapstyles，该软件包应有助于解决此问题:

I have developed a package ggmapstyles, which should help with this problem: https://github.com/dr-harper/ggmapstyles

该程序包使您可以从时髦的地图中选择设计，并且使用页面中的样式就像复制一样简单URL变成样式:

The package lets you select designs from Snazzy Maps, and using the style from the page is as simple as copying the URL into the style:

devtools::install_github("mikey-harper/ggmapstyles")
library(ggmapstyles)

map <- get_snazzymap(center = 'London', 
                     mapRef = "https://snazzymaps.com/style/61/blue-essence")
ggmap(map)

如果找不到喜欢的设计，则可以免费加入Snazzy Maps，并在网络浏览器中进行自己的自定义设计.

If you don't find a design you like, you can join Snazzy Maps for free and make your own custom design within the web browser.
