Creating figures like the paper ‘Completeness of Digital Accessible Knowledge of Plants of Ghana’ Part 1
Recently I got to read the paper about Completeness of Digital Accessible Knowledge DAK by Alex Asase and A. Townsend Peterson. I really enjoyed reading the paper and liked the way the figures are presented. There is a lot of overlap of this with my work on package bdvis (of course under guidance of Town Peterson). So I thought I will share so...
