I have longitudinal data with "id" as unique identifier, "timevar" as
the time variable and an outcome variable I call "count." The timevar
contains the elapsed time in minutes. I would like to exclude all
zeros where there are 3 or more consecutive zeros for each person. Can
anyone help?

id  timevar count
1    1         56
1    2         2
1    3         0
