將R package ggmap與Google Directions API令牌一起使用

Question

我正在使用ggmap的“路線”功能來使用Google的Driving Directions API繪制行車路線。 我可能需要超過每日2,500個API限制。 我知道要超過這個門檻，我必須支付0.50美元/ 1000美元的點擊費並注冊Google Developers API令牌。 但是，我沒有看到ggmap庫或路由功能中的任何參數允許我輸入我的令牌和密鑰信息，以便我可以超過閾值。 我錯過了什么？

Answer 1

我已經編寫了googleway軟件包來訪問google maps API，您可以在其中指定令牌密鑰

例如

library(googlway)

key <- "your_api_key"
google_directions(origin = "MCG, Melbourne",
                  destination = "Flinders Street Station, Melbourne",
                  key = key,
                  simplify = F) ## use simplify = T to return a data.frame
