convertPaths: 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).

Examples

filenames <- c("/home/user1/Documents/file.txt", "/Users/user1/Documents/file.txt")
oldPaths <- dirname(filenames)
newPaths <- c("/home/user2/Desktop", "/Users/user2/Desktop")
convertPaths(filenames, oldPaths, newPaths)

r1 <- raster::raster(system.file("external/test.grd", package = "raster"))
r2 <- raster::raster(system.file("external/rlogo.grd", package = "raster"))
rasters <- list(r1, r2)
oldPaths <- system.file("external", package = "raster")
newPaths <- file.path("~/rasters")
rasters <- convertRasterPaths(rasters, oldPaths, newPaths)
lapply(rasters, raster::filename)
