gtrendsR geo MSA/地区代码 [英] gtrendsR geo MSA/Area Code
问题描述
我正在使用R Package gtrendsR收集Google趋势数据.我正在尝试提取每个大都市统计区域(MAS)的数据,但是区号也很好.到目前为止,我只设法获取了状态级别的数据.这是代码.
I am gathering Google Trends data using the R Package gtrendsR. I am trying to pull data for each metropolitan statistical area (MAS) but area code would also be good. So far I have only managed to get the state-level data. Here is the code for that.
example <- gtrends("car", geo="US-FL")$interest_over_time
我已经针对MSA尝试了以下方法:
I have tried the following for the MSA:
example2 <- gtrends("car", geo="US-FL-Jacksonville FL")$interest_over_time
以及区号:
example3 <- gtrends("car", geo="US-FL-904")$interest_over_time
我收到错误消息,说该程序包无法检索有效的代码.在与数据包相关联的data("countries")中,代码仅用于状态级别,例如佛罗里达的US-FL.
I get errors saying that the package cannot retrieve valid codes. In data("countries") associated with the package, the codes are only for state-level - e.g. US-FL for Florida.
我很想知道如何使用此程序包按照上面的example2和example3中所述的方式来检索更细粒度的数据.
I would be interested in knowing how I can retrieve more granular data with this package, along the lines described in example2 and example3 above.
推荐答案
要检索佛罗里达州杰克逊维尔"的数据,应使用geo = "US-FL-561"
:
To retrieve data for "Jacksonville, FL", you should use geo = "US-FL-561"
:
example2 <- gtrends("car", geo = "US-FL-561")$interest_over_time
要查找城市的地理位置代码,可以使用以下代码(您可以将"US-FL"
替换为所需的任何国家/地区代码)
To find the geo code for cities, you can use this code (you can replace "US-FL"
by any country-states code you want):
data("countries")
codes <- unique(countries$sub_code[substr(countries$sub_code, 1,5) == "US-FL"])
codes
#[1] US-FL US-FL-571 US-FL-592 US-FL-561 US-FL-528 US-FL-534 US-FL-656 US-FL-539 US-FL-548 US-FL-530
countries[countries$sub_code %in% codes[2:length(codes)],]
# country_code sub_code name
#122665 US US-FL-571 Ft. Myers-Naples, FL
#122666 US US-FL-592 Gainesville, FL
#122667 US US-FL-561 Jacksonville, FL
#122668 US US-FL-528 Miami-Ft. Lauderdale, FL
#122670 US US-FL-534 Orlando-Daytona Beach-Melbourne, FL
#122671 US US-FL-656 Panama City, FL
#122672 US US-FL-539 Tampa-St Petersburg (Sarasota), FL
#122673 US US-FL-548 West Palm Beach-Ft. Pierce, FL
#122680 US US-FL-530 Tallahassee, FL-Thomasville, GA
功能
如果更容易,您还可以将代码作为函数编写:
Function
If easier, you can also write the code as a function:
city_code <- function(geo){
codes <- unique(countries$sub_code[substr(countries$sub_code, 1,5) == geo])
if(length(codes) > 1){
countries[countries$sub_code %in% codes[2:length(codes)], 2:3]
} else{
message('No city code for this geo')
}
}
