Reading wav files into RapidMiner using R

I prefer using RapidMiner to create complex processes. It's easier to get the big picture perspective of a process using the connected operator view. This means I tend to try and bring things into RapidMiner from elsewhere where possible.

An example of this is reading wav files; very easy in R. Here's an example process that uses R to do this and imports the results into RapidMiner.

You will need to uncomment the line in the R script to fetch the tuneR library.

You will also have to provide the path to the wav file you want to import.

There may be wav files it cannot read but this is an exercise for the reader.
