    year - a numeric vector of years 1950-2015 (66 years)

  `vals`

    population - a numeric vector of the estimated total population in thousands in 233 countries and regions

### Examples

    ## load the Population dataset
    dataf = dataf.population()

    ## view the classes
    unique(dataf$labels)

    ## access the 5th point of the 2nd object
    dataf$dataf[[2]]$args[5]
    dataf$dataf[[2]]$vals[5]

    ## plot the data
    ## Not run:
    labels = unlist(dataf$labels)
    plot(dataf,
      main = "World population data",
      xlab="Year", ylab="Population (in thousands)"
      )
    ## End(Not run)

    ## compute the integrated and infimal depths of the data curves
    ## with respect to the same set of curves
    depthf.fd1(dataf$dataf, dataf$dataf)
