Opening a file in mode "r+" or "r+b"
While using the file functions have found a few more issues (on both Unix
and Windows) ie
R documentation:
In the "close" description (base package) we see that the possible values
for the mode 'open' the "r+" and "r+b" values are repeated, and are
incorrect the second time. The second set actually corresponds to the "w+" /
"w+b", see

Garbage collection: RW1041
Have searched through the archives but have been unable to find any related
issues - hopefully I'm not bringing up an old topic.
Am using RW1041 on a Windows NT on a machine with 1Gb of memory. Have a
function doit() that reads in a chunk of data using readBin, performs a
regression, saves out coeffs and then returns. When using Rgui with the
default memory limit of 256Mb I'm able to

isSeekable returns F on seekable file
Hi,
Seems that on RWin 1.7.0 and 1.6.2 isSeekable returns F on binary files,
while seek() works as expected on the same connection - see example below:
> con = file(nm, "rb")
> isSeekable(con)
[1] FALSE
> readBin(con, double(), 10)

[PATCH] rsync on cygwin - textmode config files
I've been running rsync-2.4.2 with an old patch of mine for some time for
backup purposes. Due to the recent remote bug, I thought it was time to
upgrade, even if the host was behind a firewall.
So I dug up the old patch (2.5.2 version attached), that I think I sent ages
ago to this list as well. It does the following:

lm.fit peak memory usage
Hi,
I've been running out of memory while using the lm.fit function - have
solved the problem and thought there might be interest in incorporating some
of the changes. Looked at the source and changed the following lines
storage.mode(x) <- "double"
storage.mode(y) <- "double"
z <- .Fortran("dqrls", qr = x, n = n, p = p, y = y, ny = ny,

[patch] Add `--link-by-hash' option.
This patch adds the --link-by-hash=DIR option, which hard links received
files in a link farm arranged by MD4 file hash. The result is that the system
will only store one copy of the unique contents of each file, regardless of
the file's name.
Anyone have an example of an MD4 collision so I can test that case? :)

wrtiteBin in conjunction with seek : the position in the file is not good when writing
Dear RHelp-list,
?I want to write at a specific position in a file without reading all
the file
because it is very large and I cannot read it in my RAM. But I miss
something
about the use of the command writeBin in conjunction with seek. In the
example bellow the seek
commands works well with the readBin command but not with writeBin, the

command write from the beginning of the file

rsync 2.6.0: possible sanitization bug?
Hiya.
While merging the 2.6.0 changes into our modified version of rsync, I
noticed the following bit of code in 2.6.0's options.c:
extern int sanitize_paths;
if (sanitize_paths)
sanitize_path(strdup(files_from), NULL);
filesfrom_fd = open(files_from, O_RDONLY|O_BINARY);
Since sanitize_path modifies its first argument in place, the path that

Delta-compression and --write-devices
Hello,
This is my first time posting to this list. I think I might have found a
bug, but I am not sure, so I appreciate any thought you may have.
I am running rsync 3.2.0dev from Git master revision 916faecb with the
copy-devices patch from rsync-patches master revision f22e220b on Debian
10 and I used the Debian build system to build rsync.
I am running the following command:

serialize() takes too long when serializing to a raw vector
Hello,
R version 2.4.1 (2006-12-18)
i386-pc-mingw32
Calling serialize() with a NULL connection serializes it to a raw vector. However, when the object to be serialized is large, it takes a very long time:
> system.time( serialize(matrix(0, 1000, 1000), NULL) )

Port of OpenSSH-2.1.1p4 to Cygwin
Hi,
since the previous port of OpenSSH to Cygwin, there's happened
a lot with Cygwin.
We have worked hard to allow a more smooth porting of UNIX
applications which results in two major advantages:
- There's no need to use so called `text mode' in open calls
anymore.
- With only less interventions in the applications code the concept
of real and effective uid's is supported

Single Precision (4 byte) floats with readBin
I would like to use readBin to read a binary data
file. Most of the data is 4-byte floating point but,
for some reason, only double precision appears to be
offered. I tried
fVariable=readBin(iFile,what=single());
and got 35.87879 which looks believable except that
the correct value is 3.030303. I then tried
fVariable=readBin(iFile,what=single(),4);
and got

[PATCH] Fix compile with cygwin
The underscores are wrong. The comment is also correct.
Also remove the configure.ac option. Otherwise it tries to compile the
windows unicode stuff which POSIX(cygwin) does not understand.
