See this datascience+ <https://datascienceplus.com/one-way-anova-in-r/> for the original work that inspired my efforts. Credit to Bidyut Ghosh (Assistant Professor at Symbiosis International University, India) for the original posting. Special thanks also to Dani Navarro, The University of New South Wales (Sydney) for the book Learning Statistics with R <http://dj-navarro.appspot.com/lsr/lsr-0.5.1.pdf> (hereafter simply LSR) and the lsr packages available through CRAN. I highly recommend it.
