convertPaths {reproducible}

Change the absolute path of a file

Description

convertPaths is simply a wrapper around gsub for changing the first part of a path. convertRasterPaths is useful for changing the path to a file-backed raster (e.g., after copying the file to a new location).

Usage

convertPaths(x, patterns, replacements)

convertRasterPaths(x, patterns, replacements)

Arguments

x

For convertPaths, a character vector of file paths. For convertRasterPaths, a disk-backed RasterLayer object, or a list of such rasters.

patterns

Character vector containing a pattern to match (see ?gsub).

replacements

Character vector of the same length of patterns containing replacement text (see ?gsub).

Value

A normalized path with the patterns replaced by replacements. Or a list of such objects if x was a list.
