segmentation | R Documentation |
Split signals into consecutive, overlapping segments.
segmentation(
signals,
sRates,
segments_size = 10,
step = 1,
padding = 0,
resample = max(sRates),
return_index = FALSE
)
signals |
A list of numeric vectors containing signals, or a single vector containing one signal. |
sRates |
A vector or list of integer values of the signals sample rates. |
segments_size |
The size of segments, in seconds. |
step |
The step between segments, in seconds. |
padding |
umber of previous and next epochs to pad the current epoch with. Defaults to 0. |
resample |
The sample rate to resample all signals. Defaults to to the max of the provided sample rates. |
return_index |
If TRUE, the index of segments is returned instead of the segments. |
A matrix of segments.
