Sorry, error in the URL. It should be

Works well. A couple of things I noticed:
(1)
md5sum is being called on directories, which causes warnings. (If this
is not viewed as undesirable, please ignore the rest of this comment.)
Should this be the responsibility of the user (by passing arguments to
list.files)? In the example, changing
fileSnapshot(dir, file.info=TRUE, md5sum=TRUE)
to
fileSnapshot(dir, file.info=TRUE, md5sum=TRUE, include.dirs=FALSE,
recursive=TRUE")
gets rid of the warnings. But perhaps the user just wants to exclude
directories for the md5sum calculations. This can't be controlled from
fileSnapshot.
I don't see the warnings, I just get NA values. I'll try to see why
there's a difference. (One possibility is my platform (Windows);
another is that I'm generally testing in R-patched and R-devel rather
than the 3.0.1 release version.) I would rather suppress the warnings
than make the user avoid them.
Or, should the "if (md5sum)" chunk subset "fullnames" using file_test
or file.info to exclude directories (and then fill in the directories
with NA)?
(2)
If I run example(changedFiles) several times, sometimes I get:
chngdF> changedFiles(snapshot)
File changes:
mtime md5sum
file2 TRUE TRUE
and other times I get:
chngdF> changedFiles(snapshot)
File changes:
md5sum
file2 TRUE
I wonder why.
Sometimes the example runs so quickly that the new version has exactly
the same modification time as the original. That's the risk of the
mtime check. If you put a delay between, you'll get consistent results.
