library(amapGeocode)

# Before the `convertCoord()` is executed,

# or set by key argument in `convertCoord()`

# get result of converted coordinate system as a data.table
convertCoord("116.481499,39.990475", coordsys = "gps")
# get result of converted coordinate system as a XML
convertCoord("116.481499,39.990475", coordsys = "gps", to_table = FALSE)
