Dear All,

Change the format of the start and end columns so that data appear as the
day of the year. For instance: Apr 24 rather than 115.

The idea is that I want the non=leap years to be 366 days instead of being
365 days. ie. Each year must have 366 days. for example: in the column
Start2, Apr 18 will be Apr 17.

> head(Samaru)
  Year Start End Length Start2   End2
1 1930   108 288    180 Apr 18 Oct 15
2 1931   118 288    170 Apr 28 Oct 15
3 1932   115 295    180 Apr 24 Oct 21
4 1933   156 294    138 Jun 05 Oct 21
5 1934   116 291    175 Apr 26 Oct 18
6 1935   134 288    154 May 14 Oct 15

Any idea is welcome. Thamks!!!!
