These functions are here for reference and testing purposes.  They are
wrappers to tools::Rdiff and rely on an existing system diff utility.
You should be using ses or diffChr instead of
Rdiff_chr and diffPrint instead of Rdiff_obj.
See limitations in note.
Rdiff_chr(from, to, silent = FALSE, minimal = FALSE, nullPointers = TRUE)Rdiff_obj(from, to, silent = FALSE, minimal = FALSE, nullPointers = TRUE)
the Rdiff output, invisibly if silent is FALSE
Rdiff_chr(letters[1:5], LETTERS[1:5])
Rdiff_obj(letters[1:5], LETTERS[1:5])
character or object coercible to character for Rdiff_chr,
any R object with Rdiff_obj, or a file pointing to an RDS object
character same as from
TRUE or FALSE, whether to display output to screen
TRUE or FALSE, whether to exclude the lines that show the actual differences or only the actual edit script commands
passed to tools::Rdiff
Rdiff_chr runs diffs on character vectors or objects coerced to
character vectors, where each value in the vectors is treated as a line in a
file.  Rdiff_chr always runs with the useDiff and Log
parameters set to TRUE.
Rdiff_obj runs diffs on the printed representation of
the provided objects.  For each of from, to, will check if they
are 1 length character vectors referencing an RDS file, and will use the
contents of that RDS file as the object to compare.
