Hi,
Recently I noticed file.copy() would discard the file mode
information. Is this the expected behaviour or a bug for file.copy()?
> file.create('testfile')
[1] TRUE
> file.info('testfile')
size isdir mode mtime ctime
testfile 0 FALSE 644 2011-03-05 17:06:39 2011-03-05 17:06:39
atime uid gid uname grname
testfile 2011-03-05 17:06:40 1000 1000 yihui yihui
> Sys.chmod('testfile', '0755')
> file.info('testfile')
size isdir mode mtime ctime
testfile 0 FALSE 755 2011-03-05 17:06:39 2011-03-05 17:06:59
atime uid gid uname grname
testfile 2011-03-05 17:07:00 1000 1000 yihui yihui
> file.copy('testfile', 'testfile2')
[1] TRUE
> file.info('testfile2')
size isdir mode mtime ctime
