Move/copy image files between directories

Source: R/move_images.R
move_images.Rd

move_images moves/copies image files created by warbleR between directories (folders).

Usage

move_images(
  from = NULL,
  to = NULL,
  it = "all",
  cut = TRUE,
  overwrite = FALSE,
  create.folder = TRUE,
  folder.name = "image_files",
  parallel = 1,
  pb = TRUE
)

Arguments

from

Directory path where image files to be copied are found. If NULL (default) then the current working directory is used.

to

Directory path where image files will be copied to.

it

A character vector of length 1 giving the image type to be used. "all", "tiff", "jpeg" and "pdf" are admitted ("all" includes all the rest). Default is "all".

cut

Logical. Determines if files are removed from the original location after being copied (cut) or not (just copied). Default is TRUE.

overwrite

Logical. Determines if files that already exist in the destination directory should be overwritten. Default is FALSE.

create.folder

Logical. Determines if files are moved to a new folder (which is named with the "folder.name" argument). Ignored if 'to' is provided. Default is TRUE.

folder.name

Character string with the name of the new folder where the files will be copied to. Ignored if 'to' is provided. Default is "image_files".

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.

Value

Image files moved into user-defined folders.

Details

This function aims to simplify the manipulation of the image files generated by many of the warbleR function. It copies/cuts files between directories.
