relabel_colms: Relabel columns to match the selection table format

In Rraven: Connecting R and 'Raven' Sound Analysis Software

Description

relabel_colms relabels columns to match the selection table format (as in the R package warbleR)

Usage

relabel_colms(X, extra.cols.name = NULL, extra.cols.new.name = NULL, 
khz.to.hz = FALSE, hz.to.khz = FALSE, waveform = FALSE)

Arguments

X	Data frame imported from Raven.
extra.cols.name	Character vector with the names of additional columns to be relabeled. Default is NULL. 'extra.cols.new.name' must also be provided.
extra.cols.new.name	Character vector with the new names for the additional columns to be relabeled. Default is NULL. 'extra.cols.name' must also be provided.
khz.to.hz	Logical. Controls if frequency variables ('top.freq' and 'bottom.freq') should be converted from kHz (the unit used by other bioacoustic analysis R packages like warbleR) to Hz (the unit used by Raven). Default is FALSE.
hz.to.khz	Logical. Controls if frequency variables ('top.freq' and 'bottom.freq') should be converted from Hz (the unit used by other bioacoustic analysis R packages like Raven) to kHz (the unit used by warbleR). Default is FALSE. Ignored if 'kHz.to.hz' is TRUE.
waveform	Logical to control if 'waveform' related data should be included (this data is typically duplicated in 'spectrogram' data). Default is FALSE (not to include it).

Details

This function relabels columns to match the selection table format to match then ones used by other bioacoustic analysis R packages like warbleR.

Value

The function returns the input data frame with new column names for time and frequency 'coordinates' and sound files and selections.

Examples

# Load data
data(selection_files)

#save 'Raven' selection tables in the temporary directory 
writeLines(selection_files[[5]], con = file.path(tempdir(), names(selection_files)[5]))

 
#'# import data to R
rvn.dat <- imp_raven(all.data = TRUE, path = tempdir()) 

names(rvn.dat)

# Select data for a single sound file
rvn.dat2 <-  relabel_colms(rvn.dat)

names(rvn.dat2)

# plus 1 additional column
rvn.dat2 <-  relabel_colms(rvn.dat, extra.cols.name = "selec.file", "Raven selection file")

names(rvn.dat2)

# plus 2 additional column 
rvn.dat2 <- relabel_colms(rvn.dat, extra.cols.name = c("selec.file", "View"), 
c("Raven selection file", "Raven view"))
 
names(rvn.dat2)
