Julendat function to identify lengths of continuous measurements

Description

This is a function taken from Julendat to identify lengths of continuous measurements in (eco-)climatological measurement series.

Usage

gfNogapLength(gaps, data.dep, ...)

Arguments

gaps	A data.frame or list. Usually created from gfGapLength.
data.dep	An object of class ki.data, or a filepath that can be coerced to ki.data. The data set under investigation.
...	Additional arguments. Currently not in use.

Value

A list containing start, end, and length of each continuous measurement.
