to_sound_selection converts Raven's selection files into sound selection files

Usage

to_sound_selection(path = NULL, dest.path = NULL, recursive = FALSE,
 parallel = 1, pb = TRUE, sound.file.path, sound.file.col)

Arguments

path

A character string indicating the path of the directory in which to look for the 'Raven' selection (text) files. If not provided (default) the function searches into the current working directory.

dest.path

A character string indicating the path of the directory in which sound selection tables will be saved. If not provided (default) files will be saved in directory where the original raven selections were found.

recursive

Logical. If TRUE the listing recurses into sub-directories.

parallel

Numeric. Controls whether parallel computing is applied. It specifies the number of cores to be used. Default is 1 (i.e. no parallel computing).

pb

Logical argument to control progress bar. Default is TRUE.

sound.file.path

A character string indicating the path of the directory containing the sound file(s). This argument is required.

sound.file.col

A character string with the name of the column containing the sound file names in the selection text files. Required.

Value

Sound selection table file(s) saved in 'dest.path' or in the working directory.

Details

The function converts Raven's selection tables to sound selection tables. Sound selection table is a more convenient format as it can be open directly in Raven (or drag-and-drop) and will automatically open the associated sound file. Multiple files can be simultaneously converted. Files must be in '.txt' format. Selection files including data from multiple recordings can be converted only if all the correspondent sound files are found in the same directory. Note that no data is imported into the R environment.

Examples

{

#load data 
data(selection_files)

# save 'Raven' selection tables in the temporary directory
out <- lapply(1:2, function(x)
writeLines(selection_files[[x]], con = file.path(tempdir(), names(selection_files)[x])))

# try drag and drop selection files into Raven (shouldn't work)

# now convert files
to_sound_selection(sound.file.path = tempdir(), 
sound.file.col = "Begin Path", path = tempdir())

# try drag and drop into Raven again (should work now)
}
#> 'sound.file.col' not found in at least 1 selection file
