a shiny app for graphing created for BIO 225, Experiments in Ecology and Evolution, at UMass Dartmouth
BGRbasic.R is a single-file version of the app. It does not use the data and www files. Students with limited R experience can run BioGraphR from RStudio with the package 'shiny' installed.
The current version of BGRbasic has these functions:
