In sen2r: Find, Download and Process Sentinel-2 Data

Expand a path with a parent directory

Description

Accessory function which checks if a path is absolute or relative; if relative, use a specified parent directory instead than the working directory to expand it. Useful for functions which accept more than one path as arguments, in which one of them contains the absolute position, and the others do not.

Usage

expand_path(path, parent = getwd(), silent = TRUE, normalize = TRUE)

Arguments

path	The path name (character) to check ad eventually expand.
parent	The parent directory (character) to use if path is relative (default value: the working directory).
silent	Logical value: if TRUE (default), no message are shown; if FALSE, a message inform if parent were applied or not; if NA, a warning is returned if path is expanded, nothing if it is already an absolute path.
normalize	Logical value: if TRUE (default), the path is normalised (normalizePath() is applied); if FALSE it is simply appended.

Value

The path eventually expanded.
