Convert wave file into single channel EMG file.

1	as.EMG(wave, downsample = FALSE, samp.freq)

`wave`	An audio wave of class `"Wave"` read in by `readWave`.
`downsample`	logical. If `TRUE` (default), then the wave will be downsampled to `samp.freq`.
`samp.freq`	numeric. The new sample frequency. Defaults to 11025.

This function takes as imput an audio wave file read in using the readWave function from the tuneR package. The returned wave has print and plot methods. By default, plotting reduces the number of points to 1/10 of the original wave using the downsample parameter.

Vector of class "EMG". Class "EMG" has print and plot methods.
