人類死亡率資料庫

人類死亡率資料庫是馬克斯普朗克人口研究所的一個專案，該專案為那些可獲得或多或少可靠統計資料的國家收集和預處理人類死亡率資料。

# load required packages
library(tidyverse) 
library(extrafont)
library(HMDHFDplus)

country <- getHMDcountries()

exposures <- list()
for (i in 1: length(country)) {
        cnt <- country[i]
        exposures[[cnt]] <- readHMDweb(cnt, "Exposures_1x1", user_hmd, pass_hmd)
        # let's print the progress
        paste(i,'out of',length(country)) 
} # this will take quite a lot of time

請注意，引數 user_hmd 和 pass_hmd 是人類死亡率資料庫網站的登入憑據。為了訪問資料，需要在 http://www.mortality.org/ 建立一個帳戶，併為 readHMDweb() 功能提供自己的憑據。
