My GPS device

Details

The data frame ccc came from when I was walking back to my office from a meeting and decided to take the scenic route and started the GPS. The data frame h2h is a trip from my office to another for a meeting. The first part is traveling by car, the last part by foot from the parking lot to the building. Speed is a mixture of distributions. The data frame towork came from driving to work one morning (the first point is where the GPS got it's first lock, not my house). The overall trip was mostly NorthWest but with enough North and NorthEast that a simple average of direction shows SouthEast, good example for circular stats.
