file_cp_ts: Copy a file to a new location conditionally

In pat-s/2019-feature-selection: Research Compendium package for the publication "Monitoring forest health using hyperspectral imagery: Does feature selection improve the performance of machine-learning techniques?"

Description

By default the copying is only done if the new file is newer than an already existing file. The main goal of this function is to have one wrapper script which calls to this function which copy only files that have recently changed. This avoids lots of uneeded diffs in version control.

Usage

file_cp_ts(file_in, dir_out)

Arguments

file_in	The file to be moved
dir_out	The directory to be moved to

Examples

library("fs")
file_touch("test.xy")
file_cp_ts("test.xy", "log/")

# now both files are equal, no copying will be done
file_cp_ts("test.xy", "log/")
