In gisma/parseSpeciesList: parse running beetle species lists as provided by the beetle enthusiasts

Description

cleanSpeciesDf is a function to clean a dataframe as provided by the enthusiasts (coleopterists) of the beetle community.

It uses the full power of df manipulation in R and is way (about 35 times ;) faster than the parseSpeciesList approach

The resulting dataframe is a not normalized relation ( so it means a huge table with mostly redundant informations).

It looks like:

familiy; genus; subgenus; country[1];country[2];country[n];...
alpestris; STAPHYLINIDAE; Quedius; Raphirus;0;1;1;...
aereipennis; STAPHYLINIDAE; Quedius; Raphirus;1;0;1;...
. . .

Usage

cleanSpeciesDf(inputFile)

Arguments

inputTXT

a Text of the specified format
