gen.sessions: Detect staying sessions of user

In caesar0301/movr: Analyzing and Visualizing Human Mobility Data

Detect staying sessions of user

Description

This function removes duplicate location records in user's mobility trajectory. Successive records at the same location are merged into a single session (with interval less than 'gap') recording the starting and ending times.

Usage

gen.sessions(x, y = NULL, t = NULL, gap = 0.5 * 3600, unite.sep = "_")

Arguments

x, y, t	see parameters of stcoords
gap	the time tolerance (sec) to combine two continuous observations
unite.sep	a separator to combine x and y coordinators into one column, see also stcoords

See Also

flowmap, flowmap2, flow.stat

Examples

data(movement)
u1 <- movement %>% dplyr::filter(id==2)

## 1-column location indicators
head(gen.sessions(u1$loc, t=u1$time))

## 2-column location coordinates
head(gen.sessions(u1$lon, u1$lat, u1$time))
