我正在使用R包WDI，该包允许通过其API导入世界银行数据。问题是我想查看该地区的所有国家/地区，例如撒哈拉以南非洲。但是为此，我需要指定许多国家(SSH现在为49)。
首先，这样做效率低下，特别是考虑到data.worldbank.org上的数据浏览器确实允许您选择区域。
但是，真正的问题是，对于(我猜是)世界银行API，要处理的国家/地区数量成问题，因为太多的国家/地区会产生HTTP错误。使我不得不将请求分为两部分。
但是，使用更有效的ALL值时，即使观察到的次数高得多，也不会出现错误。
现在，我的代码如下所示:
library(WDI)
COUNTRIES1 <- c( "AGO","BEN","BWA","BFA","BDI","CMR","CPV","CAF","TCD","COM","ZAR","COG","CIV","GNQ","ERI","ETH","GAB","GMB","GHA","GNB","GIN","KEN","LSO","LBR","MDG" )
COUNTRIES2 <- c( "MWI","MLI","MRT","MUS","MYT","MOZ","NAM","NER","NGA","RWA","STP","SEN","SYC","SLE","SOM","ZAF","SSD","SDN","SWZ","TZA","TGO","UGA","ZMB","ZWE" )
INDICATORS <- c("NY.GDP.PCAP.KN", "SP.DYN.TFRT.IN", "SP.POP.TOTL")
LONG1 <- WDI( country=COUNTRIES1, indicator=INDICATORS, start=1960, end=2009, extra=FALSE)
LONG2 <- WDI( country=COUNTRIES2, indicator=INDICATORS, start=1960, end=2009, extra=FALSE)
LONG <- merge( LONG1, LONG2, by=intersect( names(LONG1),names(LONG2) ), all=TRUE )
我尝试使用
SSH作为国家/地区代码，但这给出了所有SSH国家/地区的汇总，而不是所有观察结果。有任何想法吗？
最佳答案
您可以下载所有国家/地区的数据
并使用Region过滤结果。
library(WDI)
indicators <- c("NY.GDP.PCAP.KN", "SP.DYN.TFRT.IN", "SP.POP.TOTL")
d <- WDI("all", indicators, extra=TRUE, start=1960, end=2009)
# Discard unwanted rows
d <- d[ which(d$Region == "Sub-Saharan Africa"), ]
# Discard unwanted columns
d <- d[,1:6]
head(d)
