In camtrapR: Camera Trap Data Management and Preparation of Occupancy and Spatial Capture-Recapture Analyses

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?

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.

Value

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

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)
