createStationFolders: Create camera trap station directories for raw camera trap images

Description

This function creates camera trap station directories, if needed with camera subdirectories. They can be used as an initial directory structure for storing raw camera trap images.

Usage

createStationFolders(inDir,  stations,  cameras, createinDir
)

Arguments

inDir

character. Directory in which station directories are to be created

stations

character. Station IDs to be used as directory names within inDir

cameras

character. Camera trap IDs to be used as subdirectory names in each station directory (optionally)

createinDir

logical. If inDir does not exist, create it?

Value

A data.frame with station (and possibly camera) directory names and an indicator for whether they were created successfully.

Details

The empty directories serve as containers for saving raw camera trap images. If more than 1 camera was set up at a station, specifying cameras is required in order to keep images from different cameras separate. Otherwise, generic filenames (e.g., IMG0001.JPG) from different cameras may lead to accidental overwriting of images if images from these cameras are saved in one station directory.

Examples

## Not run: 
# 
# # create dummy directory for tests (this will be used as inDir)
# # (normally, you'd set up an empty directory, e.g. .../myStudy/rawImages)
# wd_createStationDir <- file.path(tempdir(), "createStationFoldersTest")
# 
# # now we load the sample camera trap station data frame
# data(camtraps)
# 
# # create station directories in wd_createStationDir
# StationFolderCreate1 <- createStationFolders (inDir       = wd_createStationDir,
#                                               stations    = as.character(camtraps$Station),
#                                               createinDir = TRUE)
#   
# StationFolderCreate1
# 
# # check if directories were created
# list.dirs(wd_createStationDir)
# 
# ## End(Not run)
