signalcovariates
character vector of covariate names from signalframe to
add as columns
Value
A dataframe with dim = c(n,K+j) where n is the
number of separate sounds, K is the number of microphones, and j is the
number of covariates (by default j = 0).
Details
This function extracts signal or noise data from a capthist object where
is stored in the `signalframe' attribute. in a natural sound x microphone
table. There is no equivalent replacement function.
The signalcovariates argument may be used to specify additional
columns of the signal frame to collapse and add as columns to the right
of the actual signal data. Ordinarily there will be multiple rows in
signalframe for each row in the output; the covariate value is taken
from the first matching row.
