sudo apt-get install libfftw3-3 libfftw3-dev libsndfile1 libsndfile1-dev r-cran-rgl bwidget
The current installation instructions for seewave do not include the installation of the BWidget package which causes issues when you try to load the package in R:
[tcl] can't find package BWidget.
You may then proceed to install the seewave package within R:install.packages("tuneR, "seewave");
