I had a question from someone about why they see different symbols for the R sound even though people are talking about the same one...
The symbol \r\ may be a broad description of the R sound overall, or it might more specifically represent the trilled R. Jim Johnson gives you an introduction to this concept of Broad vs Narrow or Phonemic vs Phonetic transcription with regards to the R sound, getting into a couple of additional R symbols from the International Phonetic Alphabet.
