Given a geographical coordinate (decimalLongitude/ decimalLatitude) the elevation data is assigned from an elevation database (Headers: decimalLongitude/ decimalLatitude/ elevation).

assignElevation(data = NULL, path.data = NULL, rd.frmt = "readRDS",
  elevations.db = NULL, round.coord = 1, wrt.frmt = "saveRDS",
  save.assigned.in = NULL, save.unassigned.in = NULL)

`data`	Vector of characters. Name of the input file.
`path.data`	Vector of characters. Path to the input file.
`rd.frmt`	Vector of characters. The file format to read. By default it will be read as a R object using the `'readRDS'` argument, but it can be read as a plain text file, using the `'readTXT'` argument. See details.
`elevations.db`	Data.Frame object. The elevations database, tree columns (decimalLatitude, decimalLongitude, elevation).
`round.coord`	Numeric vector. Decimal to round the coordinate to assign the elevation. This value must be same of the coordinate resolution of database assigned as argument on `elevation.db` parameter. Example: the resolution of the coordinates in the databases assigned on `elevation.db` is one decimal, then `round.coord` must be equal to 1 (round.coord=1).
`wrt.frmt`	Vector of characters. Format to save output file. By default it will be written as a R object using the `'saveRDS'` argument, but it can be saved as plain text using the `'saveTXT'` argument. See details.
`save.assigned.in`	Vector of characters. Path to write the output file with only the coordinates whose elevation was assigned. Output file will be called <alt.assigned>.
`save.unassigned.in`	Vector of characters. Path to write the output file with only the coordinates whose elevation was not assigned. Output file will be called <alt.unassigned>. See details.

For more details about the formats to read and/or write, see the readAndWrite function.

The coordinates whose elevations were not assigned could be checked with elevFromGg. This function can download data directly from Google Maps Elevation API [1]

The headers of the input file must follow the Darwin Core standard [2]. The user can see the guide using data('ID_DarwinCore) command.

A table data.frame class with coordinates and their respective elevation. A table with coordinates whose elevations were not assigned. A table of information.
