In edwardlavender/flapper: Routines for the Analysis of Passive Acoustic Telemetry Data

Check a directory exists

Description

This function checks whether a directory exists and, if not, returns an informative error message. The inputted directory can be edited with the addition of a '/' if requested.

Usage

check_dir(arg = deparse(substitute(input)), input, check_slash = FALSE)

Arguments

arg	(optional) A character string which defines the argument of a parent function.
input	A character string which defines a directory.
check_slash	A logical input that defines whether or not to check the end of the directory string for '/'. If TRUE and a '/' is lacking, this is added to the returned directory.

Value

The function checks whether or not a directory exists. If so, the function returns either the directory as inputted, or the directory with a '/' added to the end. If not, the function returns an informative error message.
