countryExists: Find if country exists for a given year

In SWS-Methodology/faoswsUtil: A suite of function to support the FAO new Statistical Working System

Description

Some countries like the former Soviet union or South Sudan dissolve or are formed during the period where we collect data. This function when given a country or a year returns a boolean expressing if the country exists for that year.

Usage

countryExists(countries, years, names = FALSE, warnNA = TRUE)

Arguments

countries	vector of countries. Can be either names of M49 codes
years	vector of years, must be same length as countries
names	logical. TRUE when names are given. They must correspond to the descriptions in agriculture:agriculture
warnNA	logical. By default, a warning will be given when an NA is in countries or year. Setting this to FALSE suppresses it.

Value

A vector (TRUE/FALSE) of the same length as countries and year corresponding to if they are a country or not. A warning - if this has NAs, subsetting by an NA can be problematic, i.e. result in no matches when subsetting.
