MareFrame DB aggregate NAs

A decorator for other MFDB attributes to file NAs into another group, either one created by the main function or not.

mfdb_na_group(sub_aggregate, na_group)

Arguments

sub_aggregate

An mfdb_aggregate produced by another function, e.g. mfdb_step_interval

na_group

The group to assign NAs to, e.g. "len_unknown"

Details

The NA group won't be added to any aggregate files generated by MFDB, since the output would be invalid.

Value

An mfdb_aggregate object that can then be used in querying functions such as mfdb_sample_count

Examples

length <- mfdb_na_group(mfdb_step_interval("len", 10), 'len_unknown')
