Difference R Output Files

Description

Given two R output files, compute differences ignoring headers, footers and some encoding differences.

Usage

Rdiff(from, to, useDiff = FALSE)

Arguments

from, to

filepaths to be compared

useDiff

should diff always be used to compare results?

Details

The R startup banner and any timing information from R CMD BATCH are removed from both files, together with lines about loading packages. UTF-8 fancy quotes (see sQuote and on Windows, Windows so-called ‘smart quotes’ are mapped to a simple quote. The files are then compared line-by-line. If there are the same number of lines and useDiff is false, a simple diff-like display of differences is printed, otherwise diff -bw is called on the edited files.

Value

0L if no differences were found, otherwise 1L
