read.ornitho: Read ORNITHO Data

In heibl/rornitho: Functions for Visualisation of Ornitho Bird Observations

Description

Read in the output of the online export from the ornitho homepage based on read.csv2.

Usage

read.ornitho(file, subsp = NULL, family = NULL, 
    phenology = NULL, rm.abs = TRUE)

Arguments

file	a character string giving the name of the (plain text) file including the suffix ".txt".
subsp	a character string giving the latin binomial (e.g. "Carduelis flammea") of the species that should be treated on a subspecies level. Note that this will omit all those observations that are not determined to subspecies level.
family	a character string giving the families the set of species should be limited to.
phenology	a character string giving the phenological behaviour the set of species should be limited to. Possible choices are "Standvogel", "Wintergast", "Seltenheit", "Durchzügler", "Teil- und Kurzstreckenzieher", "Langstreckenzieher", or any combination thereof.
rm.abs	logical, if TRUE (default) observations with 0 number of individuals are removed.

Details

read.ornitho matches the scientific names found in the plain text file with a set of 'canonical' names defined in data(def). Other scientific names encountered are mostly not determined to the species level and will be ignored. If this happen, read.ornitho will issue a message and print a file names "ignored.txt" to the current working directory with the scientific and vernacular names of the ignored, ie. removed, observations.

Value

a list whose elements are objects of class ornithoSpec.
