My data frame is: > str(act_data12) 'data.frame': 1687 obs. of 5 variables: $ Date : chr "2006-02-22" "2006-02-22" "2006-02-22" "2006-02-22" ... $ Dtime : chr "14:36:10" "14:36:11" "14:36:12" "14:37:38" ... $ FocusApp_seq: chr "useractivity_act" "4" "3" "0" ... $ App_duration: int 1 1 86 58 1 1 9 3 1 41 ... $ Frequency : int 0 0 22 0 1 0 0 0 0 0 ...
I used: gh<-with(act_data12, aggregate(Frequency, by=list(Date, Dtime, FocusApp_seq, App_duration), sum)) Error info: Error in unlist(y, recursive = FALSE) : promise already under evaluation: recursive default argument reference or earlier problems? or R exited when running..
