R (version 3.6.3) programs to replicate the results in "Distributionally adjusted life expectancy as a life table function"

* Data were downloaded from the Human Mortality Database (HMD), https://www.mortality.org/, on May-28th 2019.
  The exact data for download can be found in https://www.mortality.org/cgi-bin/hmd/hmd_download.php, 'Period data':
  'Life Tables - Male' - 'lt_male.zip'
  'Life Tables - Female' - 'lt_female.zip'
  'Life Table - Both Sexes' - 'lt_both.zip'

  From these files we use the 1x1 (by age and year) life tables only for all countries.

***********
* DALE00.r: Adds inequality columns to the HMD life tables: distributionally adjusted life expectancy & inequality index.
            By defaults it generates the new columns for alpha = 0. Change the parameter 'a' for other results!
            It stores a csv file, 'dalelt.csv', with the additional information for subsequent processing.
* DALE01.r: Table 1 in the paper.
* DALE02.r: Graphs 5 and 6 of the paper. It also calculates the correlation coeffient between life expectancy and the geometric mean mentioned in the paper.
