derivePoints.RdGiven a data object and lng/lat arguments (which may be NULL [meaning infer from data], formula [which should be evaluated with respect to the data], or vector data [which should be used as-is]) return a lng/lat data frame.
derivePoints(data, lng = NULL, lat = NULL, missingLng = missing(lng), missingLat = missing(lat), funcName = "f")
| data | map data |
|---|---|
| lng | longitude |
| lat | latitude |
| missingLng | whether lng is missing |
| missingLat | whether lat is missing |
| funcName | Name of calling function (for logging) |
