set_profiles {evprof}

Classify sessions into user profiles

Description

Joins all sub-sets from the list, adding a new column Profile

Usage

set_profiles(sessions_clustered = list(), clusters_definition = list())

Arguments

sessions_clustered

list of tibbles with sessions clustered (sessionsobject of the output from function cluser_sessions()) from each sub-set

clusters_definition

list of tibbles with clusters definitions (direct output from function define_clusters()) of each sub-set

Value

tibble

Examples

# disconnect the same day (`Disconnection == 1`)
