Problems with R CMD COMPILE within Makefile (PR#885)
Dear R-developpers
This concerns a problem I posted about half a year ago on the R-help list
and to which I got some answer by Duncan Temple Lang (see below), but the
basic problem still continues. Even though I managed a workaround which is
sufficient for me Martin Maechler asked me to send a toy example of the
problem to R-bugs. So that's what I try here.
The following Makefile will not

how to find index of maximum?
Dear R-users,
Is there a simple way to find the index of the maximum of a vector?
Ex.

How to change several elements of an array simultaneously?
I have a matrix `m' and two vectors `rs' and `cs'. I want to change m at the
positions (rs[1], cs[1]), (rs[2], cs[2]), ... to 1. Obviously I can do that by
> m[rs + (cs-1) * dim(m)[1]] <- 1
but I would just be interested whether I am missing a more "intuitive" way
of doing that.
Thanks in advance, Peter

problems with read.table
Dear R users,
I have the following problem:
I have a table in ASCII-format, separated with commas. I can read it as
long as no field contains a comma itself. If one does, read.table doesn't
function even though that field is double-quoted.
Ex.:
File "test.csv":
Name,Strasse,PLZ
Jsaac,Gossauerstrassee 29,9100

Encryption
Hi All,
I am using rsync to backup our office server to our Internet server (RHE).
As an association for doctors we are looking at providing a backup service
for their practices using rsync. As it would be patient data it would need
to be encrypted. I have found a few options, namely

a nasty error
Dear R-developers
The basic function seq doesn't work properly:
> seq(1,6,by=3)
[1] 1 4 7
Looking at the source code of seq.default I found that strange fuzz thing
"+ 0.4". Taking that away the seq works fine.
My question is: Why has this fuzz thing been added?
If it was for some rounding problems I would suggest to replace "0.4" by
something much smaller.

[PATCH nbdkit] plugins: python: Add imageio plugin example
This is mainly for testing the new parallel python threading model, but
it also an example how to manage multiple connection from a plugin.
I tested this with local imageio server, serving qcow2 image on local
SSD.
Start imageio server from imageio source:
./ovirt-imageio -c test
Create test disk:
qemu-img create -f qcow2 /var/tmp/disk.qcow2 6g

[PATCH] v2v: rhv-upload-plugin: Remove unneeded auth
Old imageio proxy was using Authorization header for GET and PUT
requests. Remove unneeded authorization when sending OPTIONS request.
Remove unneeded duplicated comments about authorization for old
imageio, and replace them with a comment when we set needs_auth.

[PATCH] RFC: rhv-upload-plugin: Use imageio client
We can use now ImageioClient to communicate with ovirt-imageio server
on oVirt host.
Using the client greatly simplifies the plugin, and enables new features
like transparent proxy support. The client will use transfer_url if
possible, or fall back to proxy_url.
Since the client implements the buffer protocol, move to version 2 of
the API for more efficient pread().
Another advantage the client

Efficiency of local functions
Dear R-users
In order to speed up the performance of my program I tried to make a
function f2 (that is only called from function f1) local to f1. In that way I
pass one argument less to f2, a huge matrix. (This matrix isn't changed
inside f2, so - afaik - it is passed by reference and size doesn't matter.)
Still I would have expected that f1 would be a little faster, but the

v2v: -o rhv-upload: Use Unix domain socket to access imageio (RHBZ#1588088).
These two patches add support for using a Unix domain socket to
directly access imageio in the case where imageio is running on the
conversion host (usually that means virt-v2v is running on the RHV
node and something else -- eg. CFME scripts -- arranges that the RHV
node is the same one running imageio).
Conversions in the normal case are not affected - they happen over TCP
as usual.

malloc small pieces of memory
Hi
I have a Problem with wine. I have one Program, that allogaces many
small pieces with "malloc()" in the memory. "many" means over 2 Mio,
"small" means "from 8 to 128 bytes" in size.
Running this Program on Windows gives me ~300MB Memory Usage (according
to one of the values in the Tast manager). In Linux, "top" shows me a

Debugging dynloaded C-code with gdb
Dear R users
I have started to use gdb for debugging dynloaded C code as described in
`Writing R Extensions'. Unfortunately I have run into several problems that
I haven't been able to solve:
- using `n': how comes that the same line of code appears up to three times
(and inbetween the next line and maybe even the second next one?)
- using `print' resp. `display': How

there's more than one transfer happening?
