[R-sig-teaching] Creating data

[Jacob Wegelin]

Scott,

Have you considered looking at phonetics data?  I refer for instance to f0 (fundamental pitch) as a time series, based on recordings of speech. I think I heard that (for instance) data from recordings of native Unangax speakers (Unangan/Unangas, also called Aleut) are posted on the Web somewhere.
