Question

我正在尝试使用R库Ggmap对载体进行地理定位。

location_google_10000 <- geocode(first10000_string, output = "latlon",
    source = "dsk", messaging = FALSE)

问题是我正在使用＆＃34; dsk＆＃34; - 数据科学工具包API-因此它没有速率限制为谷歌（限制为每天2500坐标）。但是，当我尝试使用包含超过2500的向量运行时，会弹出以下消息：

Error: google restricts requests to 2500 requests a day for non-business use.

我尝试使用带有1000个地址的dsk运行代码，然后检查是否实际使用了google或dsk api：

> geocodeQueryCheck()
2500 geocoding queries remaining.

因此，由于某种原因，它不允许我使用＆＃34; dsk＆＃34;超过2500，但我确信它不使用谷歌。

我刚遇到同样的问题，发现了你的帖子。我能够通过将client和signature值设置为虚拟值来解决此问题，例如

geocode(myLocations, client = "123", signature = "123", output = 'latlon', source = 'dsk')

问题似乎出现在地理编码功能的这一部分......

if (length(location) > 1) {
        if (userType == "free") {
            limit <- "2500"
        }
        else if (userType == "business") {
            limit <- "100000"
        }
        s <- paste("google restricts requests to", limit, "requests a day for non-business use.")
        if (length(location) > as.numeric(limit)) 
            stop(s, call. = F)

userType在代码的这一部分中设置如上...

if (client != "" && signature != "") {
        if (substr(client, 1, 4) != "gme-") 
            client <- paste("gme-", client, sep = "")
        userType <- "business"
    }
    else if (client == "" && signature != "") {
        stop("if signature argument is specified, client must be as well.", 
            call. = FALSE)
    }
    else if (client != "" && signature == "") {
        stop("if client argument is specified, signature must be as well.", 
            call. = FALSE)
    }
    else {
        userType <- "free"
    }

因此，如果client和signature参数为空userType设置为“空闲”，则限制设置为2,500。通过为这些参数提供值，您将被视为“业务”用户，其限制为100,000。如果假设用户使用'Google'而不是'dsk'作为源，这是一个很好的检查，但如果源是'dsk'并且应该被覆盖则过于热心。简单的想法可能就像......

    if (source == "google") {
        if (client != "" && signature != "") {
                if (substr(client, 1, 4) != "gme-") 
                    client <- paste("gme-", client, sep = "")
                userType <- "business"
            }
            else if (client == "" && signature != "") {
                stop("if signature argument is specified, client must be as well.", 
                    call. = FALSE)
            }
            else if (client != "" && signature == "") {
                stop("if client argument is specified, signature must be as well.", 
                    call. = FALSE)
            }
            else {
                userType <- "free"
            }
    } else {
           userType <- "business"
 }

如果为其他来源计划了client或signature参数，那么这会导致问题。我会打包包作者。
