RailTrail sample data
The RailTrail data frame from the mosaic package is loaded in your workspace. RailTrail contains data collected by the Pioneer Valley Planning Commission on the usage of a local rail-trail. For each of 90 days, they recorded the rail-trail volume (number of users) and whether it was a weekday (TRUE if yes and FALSE otherwise). You will explore the trends in weekday vs weekend volume below.
