SpaccHerb


One index of diversity is species richness i.e. total number of species of a taxon present in a locality. To estimate richness, it is convenient to go on counting randomly selected individuals and recording their species names. An accumulation curve has total number of individuals or quadrats on X-axis and accumulated number of species on Y axis. 


datasets

With their permission, first letter of their names forms the name of this package, the package has been built by me and made available for the benefit of R users.
