Details
The function currently only works for the English language and does not accepts inputs that are characters, dates, or times.
Note that the toOrdinal() function of the toOrdinal package works
for multiple languages and provides a toOrdinalDate() function.
Caveat: Note that this function illustrates how numbers,
characters, for loops, and paste() can be combined
when writing functions.
It is instructive, but not written efficiently or well
(see the function definition for an alternative solution
using vector indexing).
