distance.moved: Distance moved

In dprocter/modeid: modeid: Identification of travel modes from GPS and accelerometry data

Description

a function that measures distance moved between points separated by a time window

Currently only works with coordinates in easting and northing, can be modified as needed, contact author if this is required

Usage

distance.moved(dataset, last, time.window, epoch.length)

Arguments

dataset	The dataset you want to apply this to, we assume it has been created by processing file using this package
last	whether you want the time window before (last=TRUE) or the following time window (last=FALSE)
time.window	The window across which to measure distance in seconds
epoch.length	The epoch.length you are working with, in seconds

Details

Given a dataset as input, this will output a variable of the same length as the datasets' variables. This will contain the distance of each point to the point the specified distance away.
