An analysis of avian vocal performance at the note and song levels

The rmd files are Markdown files for use in R. "PerfConst17.3.rmd" is the note-level analysis and "SongPerfConst7.1.rmd" is the song-level analysis. The current versions of the .rmd files correct minor errors in previous versions, including versions that were previously posted to Dryad. These errors were corrected before publication, so the paper is based on the corrected version of the R code. Feel free to contact me about these data at [e-mail].
