In jcvdav/cooperatR: Manipulate and wuery Dan Ovando's cooperative database

Description

Creates a data.frame containing columns that uniquely identify a fishery in the cooperatives dataset. By default, it includes original_order, entered_by, fishery_id, geographic_range_of_fishing_acti, and home_port.

Usage

get_unique(other.variables = NULL, include.spp = TRUE, to.file = FALSE,
  filename = NULL)

Arguments

other.variables	A character string specifying if other variables should be included. See the get_variables function for a list of variables available in cooperatives. If not specified, it defaults to NULL and no additional variables are returned.
include.spp	A logical indicating if the columns for target_spp and complete_name should be included. By default, it is set to TRUE.
to.file	A logical indicating if the extraction should be written to a csv file on disk.
filename	If the to.file argument is set to TRUE, the user may want to specify a particular filename. This must be a character string that specifies the desired name of the file. The user can also specify the directory relative to its current working directory with a customary approach of "./RootFolder/MyDesiredFolder/filename". There is no need to specify file extension! If NULL (de default), the file is saved as cooperatives.csv in the current working directory.

Value

a data.frame containing the desired columns
