File System Utility Functions for 'NeuroAnatomy Toolbox'
Utility functions that may be of general interest but are specifically required by the 'NeuroAnatomy Toolbox' ('nat'). Includes functions to provide a basic make style system to update files based on timestamp information, file locking and 'touch' utility. Convenience functions for working with file paths include 'abs2rel', 'split_path' and 'common_path'. Finally there are utility functions for working with 'zip' and 'gzip' files including integrity tests.
An R package containing utility functions to support the NeuroAnatomy Toolbox (nat)
Background

Installation
Released versions
From CRAN- the recommended option for simplicity and since this package is not under heavy development:
install.packages("nat.utils")Bleeding Edge
Straight from github with Hadley Wickham's devtools package:
if(!require("devtools")) install.packages("devtools")devtools::install_github('nat.utils','jefferis')Note: Windows users need Rtools to install in this way.
