In kaneplusplus/checkin: Process Check-in Data for the Analysis of Human Mobility

Get the checkins in an interval

Description

This function filters the input data frame such that the output is a similar data frame where all entries are in the specified period between start and end. The start_loc and end_loc parameters specify whether or not last observations should be carried forward. If start_loc is TRUE then a checkin occuring before the interval will be carried forward so that the location appears in the output at the beginning of the interval. If end_loc is TRUE then a checkin is carried forward to the end of the interval.

Usage

checkins_in_interval(x, time, start, end, start_loc = TRUE, end_loc = TRUE)

Arguments

x	the data frame of checkins.
time	the column denoting the timestamp.
start	the beginning of the interval.
end	the end of the interval.
start_loc	should the starting location be included? Default TRUE.
end_loc	should the end location be included? Default TRUE.

Examples

 library(dplyr)
 library(lubridate)
 data(checkins)

 x <- checkins %>%
   filter(id == 335) %>%
   arrange(timestamp)

 start <- x$timestamp[1]
 minute(start) <- 0
 second(start) <- 0

 end <- start + hours(1) - seconds(1)
 checkins_in_interval(x, "timestamp", start, end)
