Example 1

The following sample represents the ``population'' of a small town:

>> stats::sample([["1990", 10564], ["1991", 10956], 
                  ["1992", 11007], ["1993", 11123], 
                  ["1994", 11400], ["1995", 11645]])
   
                              "1990"  10564
                              "1991"  10956
                              "1992"  11007
                              "1993"  11123
                              "1994"  11400
                              "1995"  11645
      

We are only interested in the years 1990, 1991, 1992 and 1995. We create a new sample containing the rows of interest:

>> stats::row(%, 1..3, 6)
   
                              "1990"  10564
                              "1991"  10956
                              "1992"  11007
                              "1995"  11645
      

We reorder the sample:

>> stats::row(%, 4, 3, 2, 1)
   
                              "1995"  11645
                              "1992"  11007
                              "1991"  10956
                              "1990"  10564
