A new set of ID levels can be created by separating those given based on a
minimum gap in another set of data. This is useful for separating
instruments identified only by their ID into separate events in time.
Usage
sepIdGaps(id, gapdata, minGap = 3600 * 24 * 7)
Value
A new set of ID levels, named following the pattern that "ID" split into 3
would provided "ID", "ID_2" and "ID_3".
Arguments
id
existing ID levels
gapdata
data matching id with gaps to use as separators
minGap
the minimum "gap" to use in gapdata to create a new ID level
Warning
It is assumed that each vector provides is sorted by gapdata within
id. No checking is done, and so it is suggested that this only be
used on ID columns within existing, validated trip objects.
Details
The assumption is that a week is a long time for a tag not to record
anything.
