Rdiff {tools} | R Documentation |
Given two R output files, compute differences ignoring headers, footers and some encoding differences.
Rdiff(from, to, useDiff = FALSE, forEx = FALSE, Log = FALSE)
from, to |
filepaths to be compared |
useDiff |
should |
forEx |
logical: extra pruning for ‘-Ex.Rout’ files to exclude the header. |
Log |
logical: should be value include a log of differences found? |
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.
If Log
is true, a list with components status
(see
below) and out
, a character vector of descriptions of
differences, possibly of zero length.
Otherwise, a status indicator, 0L
if and only if no differences
were found.
The shell script run as R CMD Rdiff
.
