regexp problem on R 1.7.0
Hi,
Am I missing something in using regexps in R?
Below, 'egrep' means invokation of the command from the shell
prompt.
# I have
> as.character(block.dist.vals)
[1] "1e+06" "2e+06" "5e+06"
# that I wish to convert to: "1" "2" "5"
# OK (R and egrep)
> sub( "e.+06", "", as.character(block.dist.vals) )

Screen blanks after initial setup (Centos 5)
Hi,
The installation process went without noticable problems; this is
true to the setup phase immediately after the installtion.
However: after pressing "Finish" in the Setup Agent the screen
blanked on me - Ctrl-Alt-F1, Ctrl-Alt-F2, Ctrl-Alt-backspace,
Ctrl-Alt-Del didn't help. Nada.
Did someone else have encountered this? Any recommendations?
Thanks in advance.

Strange yum behavior
Hello,
'yum search R' returns an impossibly-long list. So I tried 'yum
search R.x86_64' and 'yum search R-2.3.0' and few others to no
avail. (Google revealed that R package does exist in kbsingh
repository.) However, 'yum install R' did offer to install the
correct package.
Can someone enlighten me as to why did the searches failed or

How to 'stamp' a plot with meta-data?
Dear R users,
Sometimes, for tracking purposes, I am interested to add to a
plot some metadata such as
* the date it was produced
* filename that stores the plot
* perhaps data sources, author, etc
Ideally, I would like to be able to do this for any kind of plot,
plot(), barplot(), hist(), etc.; and, to be able to produce
plots with or without the metadata by a simple toggle mechanism.

rsync + ssh: fails from cron
Hi,
My ssh set up, on both 'work' and 'home' machines uses the
private-public key authentication (key uses non-empty
passphrase). So from the 'home' shell prompt the following
works without prompting to password or passphrase:
rsync -avz --delete -e ssh remote.work.machine:publicats $HOME/work
>From cron, however, I am prompted for a password, though.

Legend text -- discrepancy between X11 and postscript
Hi,
When I place a legend on a plot it looks exactly as I intended
on the screen. However, almost always, when I export this to
postscript file, the legend's text protrudes through the legend's
frame (the latter being placed correctly).
See the appended example code. I can send the EPS file as well
for those that are interested (<4 kb; <200 lines).
I found nothing in the FAQS,

How to do aggregate operations with non-scalar functions
Hi,
I have a data set, the structure of which is something like this:
> a <- rep(c("a", "b"), c(6,6))
> x <- rep(c("x", "y", "z"), c(4,4,4))
> df <- data.frame(a=a, x=x, r=rnorm(12))
The true data set has >1 million rows. The factors "a" and "x"
have about 70 levels each; combined together they subset

How to add a top X-axis with a different logarithmic scale?
Hi,
I am trying to put on one plot two different logarithmic
scales, using the bottom and top X-axes.
Below there is an example of what I am trying to achieve,
using axTicks() -- and fails.
I already spent few hours on that, and cannot figure out from
?par and ?axTicks what I am doing wrong.

Yum, duplicate packages, 4.3->4.4 upgrade.
Hi,
I am running a CentOS 4.3 machine. I wish to move on to 4.4.
My problem is that I have some 60 duplicate packages listed
below. The kernel and gpg-pubkey packages are different
versions of the same (none for the gpg) architecture. All the
rest are a x86_64 and i[356]86 pairs.
1. Is this a problem?
2. If yes, what should I do?
a) remove the duplicates (the i[356]86) and then 4.3 ->

LVM Input/output error
Hi,
I recently installed centos for the first time and I like it!
Also, I just started working with lvm. The following warnings
are genertated whenever I run one of lvm commands on the external
usb disk (MyBook by Western Digital).
* What could be the source for those messages?
* Should I worry about them (writing into the created LV's
seems to work)?
* If yes, how to fix them?

AEC on a TI C6x - has no effect
For me, this was a memory allocation problem. I am using a private heap,
and somewhere between build 11522 and 11700, the allocation for two large
buffers was changed from calloc to speex_alloc (I am sure that this was a
cleanup change, and I have not had a chance to locate it yet). This was
overrunning my heap, and enlarging the heap solved the problem.
I suspect that Itay is having a

AEC on a TI C6x - has no effect
Itay,
I tested on C6x in May with build 11343 and 11398, and it worked fine. I just ran the same test with build 11768, and there was no cancellation, just as you saw. I will try to track this down in the next day or two. In the meantime, I suggest that you try testing with 11398.

large fonts on plots
Hi all,
I need to enlarge te fonts used oo R-plots (plots, histograms, ...) in
labels and titles etc.
I seem to be unable to figure out how to do it. The problem is that the
titles of the plots are simply unreadable when I insert them into my LaTeX
text, since they are relatively small compared to the entire plot.
I am sure it is pretty simple, can anybody give me a hint ?

[IR] Modelling of GlobalIFunc
> * Calling getBaseObject() on a GlobalIFunc returns its resolver function.
I still don't understand how it can happen looking to the code (
https://github.com/llvm/llvm-project/blob/master/llvm/lib/IR/Globals.cpp#L430).
I believe it should return nullptr (the same as if you call it from
GlobalAlias that refers to GlobalIFunc).
I don't have a strong opinion here because deriving

OT: Precautions before draining laptop battery?
Hi,
I have found some advice on the web regarding battery draining,
but no linux-specific information. Are there some steps to be

I would appreciate any advice.

AEC on a TI C6x - has no effect
Hello all,
I am attempting to integrate the AEC algorithm from Speex into an
RTP-based voice-over-IP application. The application is supposed to
operate on a TI C6412-based board, using Code Composer Studio for
development. Everything seems to be working, but the problem is that
there is no discernible difference in the output, whether the echo
cancel function is called or not.
Let me first
