我想在R中创建一个等高线图，其中数据具有时间戳，用于跟踪纬度，经度和海拔高度的移动。数据看起来像这样
TimeStamp LatitudeDegrees LongitudeDegrees AltitudeMeters
1 10:46:58 NA NA NA
2 10:47:05 NA NA NA
3 10:47:06 NA NA NA
4 10:47:07 NA NA NA
5 10:47:08 NA NA NA

8 10:47:13 37.35971 -6.572561 163.2
9 10:47:14 37.35971 -6.572560 163.2

13 10:47:18 37.35971 -6.572560 163.2
14 10:47:19 37.35971 -6.572559 163.2
15 10:47:20 37.35971 -6.572559 163.2
16 10:47:21 37.35971 -6.572559 163.2
我如何在R？
中实现这一目标
