Rename wave objects and associated metadata in extended selection tables

Description

rename_est_waves rename wave objects and associated metadata in extended selection tables

Usage

rename_est_waves(X, new.sound.files, new.selec = NULL)

Arguments

X	object of class 'extended_selection_table'.
new.sound.files	Character vector of length equals to the number of wave objects in the extended selection table (length(attr(X, "wave.objects"))).Specifies the new names to be used for wave objects and sound file column. Note that this will rename wave objects and associated attributes and data in 'X'.
new.selec	Numeric or character vector of length equals to the number of rows in 'X' to specify the 'selec' column labels. Default is NULL. If not provided the 'selec' column is kept unchanged. Note that the combination of 'sound.files' and 'selec' columns must produce unique IDs for each selection (row).

Details

This function allow users to change the names of 'sound.files' and 'selec' columns in extended selection tables. These names can become very long after manipulations used to produce extended tables.

Value

An extended selection table with rename sound files names in data frame and attributes. The function adds columns with the previous sound file names (and 'selec' if provided).

Examples

{
data("lbh.est")

# order by sound file name
lbh.est <- lbh.est[order(lbh.est$sound.files),]

# create new sound file name
nsf <- sapply(strsplit(lbh.est$sound.files, ".wav",fixed = TRUE), "[",1)

slc <- vector(length = nrow(lbh.est))
slc[1] <- 1

for(i in 2:length(slc))
if (nsf[i - 1] == nsf[i]) slc[i] <- slc[i - 1] + 1 else
slc[i] <- 1

nsf <- paste(nsf, slc, sep = "_")

# rename sound files
Y <- rename_est_waves(X = lbh.est, new.sound.files = nsf)
}
