Flag Countries Sharing Borders

Description

For those records without a match between the country described in the record and the country obtained from the geographical coordinates, the function flags if the two countries share borders. These may be useful to identify coordinates that are not problematic but that fall in another country due to rounding or precision of coordinates or to cases when the collector was not aware that a country border was crossed before obtaining the coordinate.

Usage

checkBorders(
  x,
  geo.check = "geo.check",
  country.shape = "NAME_0",
  country.gazetteer = "loc.correct",
  output = "new.col"
)

Arguments

`x`	a data.frame with the results from the coordinate validation
`geo.check`	Name of the column with the validation of the coordinates against country maps. Default to 'geo.check'
`country.shape`	Name of the column with the country name obtained from the world map based on the original record coordinates. Default to 'NAME_0'
`country.gazetteer`	Name of the column with the country name obtained from the gazetteer, based on the description of the record locality. Default to 'loc.correct'
`output`	a character string with the type of output desired: 'new.col' (new column with the result is added to the input data) or 'same.col' (results overwritten into column `geo.check`).

Value

if output is 'new.col', a new column named 'border.check' is added to the data, containing a TRUE/FALSE vector in which TRUE means countries which share border and FALSE means countries that do not share borders (country mismatch is not due to coordinates close to country borders). If output is 'same.col', the column defined by geo.check is updated with a suffix 'borders' or 'inverted' added to the validation class inside brackets.
