generate_segments: Generate analysis segments given a start and stop time.

In bwrc/colibri: Platform for automating analyses of physiological time series in R.

Description

If segmentlength is zero, the entire block length is used and no segments are created. The tolerance is given in seconds, and defaults to 1 second. The tolerance affects the last segment. If the last segment would, e.g., extend past the data, the tolerance parameter can be used to adjust when a slightly-shorter segment is accepted, and when the entire segment must be discarded.

Usage

generate_segments(time.start, time.stop, segment.length, segment.overlap,
  tolerance = 1)

Arguments

time.start	A start time in seconds.
time.stop	A stop time in seconds.
segment.length	The segment length in seconds.
segment.overlap	The segment overlap in seconds.
tolerance	The tolerance of the last segment length in seconds. Optional, default is 1.

Value

A two-column matrix with the start time (in seconds) of each segment in the first column and the stop time (in seconds) in the second column.
