A few bug fixes, Help file updates, and a new feature — plotting multiple indices on one graph (palyoplot_plotOverlaidIndices()) — tutorial coming soon. File to install is at: http://geotechnography.com/samples/palyoplot.palyoplot_0.0.16.tar.gz.
A round of testing and Palyoplot should be Beta. Feedback as always is appreciated. History of versions, changelog, and a revised sample R file are available at: http://geotechnography.com/samples/palyoplot/
