Returns sample indices (1-based) where x crosses threshold in
the chosen direction. min_distance enforces a minimum gap (in
samples) between successive events.
Usage
morie_dsp_threshold_detect(
x,
threshold,
min_distance = 1L,
direction = "above"
)
Arguments
- x
Numeric vector.
- threshold
Scalar threshold.
- min_distance
Minimum gap between events. Default 1.
- direction
One of "above", "below", "either". Default "above".
Value
Integer vector of detected indices.
