imp_syrinx: Import 'Syrinx' selections

Description

imp_syrinx imports 'Syrinx' selection data from many files simultaneously. All files must have the same columns.

Usage

imp_syrinx(path = NULL, all.data = FALSE, recursive = FALSE, 
exclude = FALSE, hz.to.khz = TRUE, parallel = 1, pb = TRUE)

Value

A single data frame with information of the selection files. If all.data argument is set to FALSE the data frame contains the following columns: selec, start, end, and selec.file. If sound.file.col is provided the data frame will also contain a 'sound.files' column. If all.data is set to TRUE then all columns in selection files are returned.

Arguments

path

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

all.data

Logical. If TRUE all columns in text files are returned. Default is FALSE. Note that all files should contain exactly the same columns in the same order.

recursive

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

exclude

Logical. Controls whether files that cannot be read are ignored (TRUE). Default is FALSE.

hz.to.khz

Logical. Controls if frequency variables should be converted from Hz (the unit used by Syrinx) to kHz (the unit used by warbleR and other bioacoustic analysis packages in R). Default if TRUE. Ignored if all.data is TRUE.

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.
