Convert coordinate from different coordinate systems to AutoNavi system

This function is a wrap of coordinate convert API of AutoNavi Map Service.
While how to input the origin coordinate is sill unstable and 95% sure that it will have a breaking change in the future. Please consider carefully if introduced this function in product environment.

convertCoord(
  locations,
  key = NULL,
  coordsys = NULL,
  sig = NULL,
  output = "data.table",
  keep_bad_request = TRUE,
  ...
)

Arguments

locations	Required. String coordinate point from other coordinate system
key	Optional. Amap Key. Applied from AutoNavi Map API official websitehttps://lbs.amap.com/dev/
coordsys	Optional. Coordinate System. Support: `gps`,`mapbar`,`baidu` and `autonavi`-not convert
sig	Optional. Digital Signature. How to use this argument? Please check herehttps://lbs.amap.com/faq/account/key/72
output	Optional. Output Data Structure. Support JSON, XML and data.table. The default value is data.table.
keep_bad_request	Optional. Keep Bad Request to avoid breaking a workflow, especially meaningful in a batch request
...	Optional. For compatibility only

Examples

if (FALSE) {
library(amapGeocode)

# Before the `convertCoord()` is executed,
# the token should be set by `option(amap_key = 'key')`
# 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)
