TimeBin: Calculate Compliance Status Given a Time Bin

In honggao110/TrackCompliance: Tools and algorithms to calculate compliance on tracking data

Description

This function calculates the distance between two consecutive stay events using their geolocations.

Usage

TimeBin(df, time = NULL, timebin = NULL, groupvar = NULL)

Arguments

df	a data frame object.
groupvar	grouping object to stratify time objects. Recommend to be ID for each individual. If groupvar is not specified, the entire data frame will be considered as one group to calculate displacement.
coor	longitude and latitude of the spatial points in the format of c("lon","lat").

Value

a list of distance values. Unit is meters.

Examples

data(mobility)
mobility_stay<- stayevent(mobility, coor = c("lon","lat"), time = "datetime", dist.threshold = 100,
time.threshold = 30, time.units = "mins", groupvar = "id")
mobility_stay<- aggregate(cbind(id, stayeventlon, stayeventlat)~stayeventgroup, mobility_stay, mean)
mobility_stay$dispm<- displacement(mobility_stay, coor = c("stayeventlon","stayeventlat"), groupvar = "id")
