DoubleMetaphone
'Double Metaphone' phonetic algorithm
DoubleMetaphone converts strings to double metaphone phonetic codes.
Usage
DoubleMetaphone(str)Arguments
- str
A character vector whose strings are to be encoded by double metaphone algorithm.
Details
An implementation of the Double Metaphone phonetic algorithm in R. If
non-ASCII characters encountered in the input character vector str, a
warning is issued and they are transliterated so that the accented characters
are converted to their ASCII unaccented versions.
Value
Returns a list with two character vectors of the same length as the input vector. The first character vector contains the primary double metaphone encodings, while the second character vector contains the alternate encodings.
Note
In case of non-ASCII characters in strings, a warning is issued and accented characters are converted to their ASCII unaccented versions.
Acknowledgement
The C code for the double metaphone
algorithm was adapted from Maurice Aubrey's perl module hosted at the
gitpan/Text-DoubleMetaphone
public
github library along with the corresponding
