drop_levels(frame_list, level_numbers)

Arguments

frame_list	a list of EprimeFrame objects
level_numbers	the whitelisted or blacklisted values for Eprime.Level

Value

for keep_levels, only log-frames where the level matches one of the level_numbers are kept. for keep_levels, log-frames where the level matches one of the level_numbers are omitted.
