powoGenera: Get list of genera from POWO

In deborazuanny/expowo: An R package for mining plant diversity and distribution data

Get list of genera from POWO

Description

It produces a CSV file listing all genera with associated number of accepted species and geographical distribution for any angiosperm family at Plants of the World Online (POWO).

Usage

powoGenera(family, uri, genus = NULL, country = NULL,
           verbose = TRUE, save = TRUE, dir, filename)

Arguments

family	Either one family name or a vector of multiple families that are present in POWO.
uri	URI address for each family to be searched in POWO.
genus	Either one genus name or a vector of multiple genera that are present in POWO. If any genus name is not provided, then the function will search all accepted genera known for the target family.
country	Either one country name or a vector of multiple countries. If country names are provided, then the function will return only the genera that are native to such countries, according to POWO.
verbose	Logical, if FALSE, the searched results will not be printed in the console in full.
save	Logical, if FALSE, the searched results will not be saved on disk.
dir	Pathway to the computer's directory, where the file will be saved provided that the argument save is set up in TRUE. The default is to create a directory named results_powoGenera and the searched results will be saved within a subfolder named by the current date.
filename	Name of the output file to be saved. Default is to create a file entitled output.

Value

Table in .csv format and saves the output on disk.
