## Spell a String Using the NATO Phonetic or the Morse Alphabet

### Description

The function splits a string into single characters and returns their representation in either the NATO phonetic alphabet or the Morse alphabet. The 26 code words in the NATO phonetic alphabet are assigned to the 26 letters of the English alphabet in alphabetical order as follows: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu. Digits 0-9 are also supported.

### Usage

    StrSpell(x, upr = "CAP", type = c("NATO", "Morse"))

### Arguments

`x` | character, the string to be encoded.
`upr` | character, a shortcut to be used to characterise capital letters. Ignored if `type` is set to `"Morse"`. No distinction is made between upper and lower case if `upr` is set to `NA` or to an empty string `""`.
`type` | the type of phonetic alphabet, either `"NATO"` or `"Morse"`.
