Usage: saveSample(s, filename, overwrite=FALSE) Arguments: s a Sample object. filename a string giving the path and the name of the destination file. overwrite logical. If FALSE and filename already exists, an error will be reported. Otherwise the old file will be deleted.</pre> <hr> <p>Example commands:</p> <pre><code>> sample = appendSample('/home/grzegorz/file1.wav', '/home/grzegorz/file2.wav') > saveSample(sample, '/home/grzegorz/output.wav', overwrite=FALSE) </code></pre> <p>I downloaded two <a href="http://freewavesamples.com/" rel="noreferrer">sample wav</a> files and it works (wavs are concatenated).
