Signal Fields
Description
Extract or replace signal attributes of a ‘capthist’ object.
Usage
signalframe(object)
signalframe(object) <- value
## S3 method for class 'capthist'
signal(object, ...)
## S3 method for class 'capthist'
noise(object, ...)
signal(object) <- value
noise(object) <- value
Arguments
object |
a ‘capthist’ object |
value |
replacement value (see Details) |
... |
other arguments (not used) |
Details
Signal attributes of a ‘capthist’ object are stored in a dataframe called the signalframe. This has one row per detection. The signalframe includes the primary field ‘signal’ and an unlimited number of other fields. To extract the signal field alone use the signal method.
These functions extract data on detections, ignoring occasions when an animal was not detected. Detections are ordered by occasion, animalID and trap.
Replacement values must precisely match object in number of
detections and in their order.
Value
For signalframe , a dataframe containing signal data and
covariates, one row per detection. The data frame has one row per
detection. See signalmatrix for a matrix with one row per
cue and columns for different microphones.
For signal and noise, a numeric vector with one element per detection.
If object has multiple sessions, the result is a list with one
component per session.
