myebirds: Calculate species totals gouped by year, country, and/or...

In sebpardo/myebird: Analyse Your Personal eBird Data

Description

myebirds calculates species totals based on data dumped by eBird (Download page: http://ebird.org/ebird/downloadMyData) after it has been cleaned with ebirdclean.

Usage

myebirds(mydata, years = 1900:format(Sys.Date(), "%Y"),
  grouping = c("Year", "Country", "Month"), wide = FALSE)

Arguments

mydata	Data frame provided by ebirdclean.
years	Range of years to calculate across, default is between 1900 and current year.
grouping	Character vector specifying how the data should be grouped for counting. Must be composed of "Year", "Country", and/or "Month". This vector is passed on directly to group_by_.
wide	String specifying whether different values should be returned in wide format and how. Must be one of the strings included in grouping. Defaults to FALSE.

Value

A data frame containing total counts divided into specified groups. If wide = FALSE then it returns a combination of the following columns, depending on grouping specified:

"Year" Year

"Country" Country using two letter codes.

"Month" Month, using full month name (from month.name()).

"n" Total species count for the specified Year, Country, and Month.

If in wide format, then the first column(s) consist of the values in grouping that are not equal to wide, while the remaining columns are unique values of the argument specified in wide.
