Many ethnobotanists are calculating indices and performing quantitative analysis with excel. Not any more! Now they can use the ethnobotanyR package to calculate common quantitative ethnobotany indices to assess the cultural significance of plant species based on informant consensus. The package closely follows two papers, one by Tardio and Pardo-de-Santayana (2008) and another by Whitney et al. (2018).
