group bunch of lines in a data.frame, an additional requirement
Thanks for pointing me out "aggregate", that works fine!
There is one complication though: I have mixed types (numerical and character),
So the matrix is of the form:
A 1.0 200 ID1
A 3.0 800 ID1
A 2.0 200 ID1
B 0.5 20 ID2
B 0.9 50 ID2
C 5.0 70 ID1
One letter always has the same ID but one ID can be shared by many
letters (like ID1)
I just want to keep track of the ID, and get

simple question on picking out some rows of a matrix/data frame
Hi,
I have a simple question about matrix/data frame manipulation. I have
a data frame that looks a something like this
X Y Z
1 0 "apples"
-1 -1 "oranges"
...
0 -1 "bananas"
and I'd like to pull out all the rows for which X and Y are (un)equal
into a submatrix.
How can I do that?
Many thanks,

RHEL 5.2 i386 image - Xen kernel doesn''t recognize the total amount of system memory
Hello,
We have installed RHEL 5.2 Server ( i386 image ) on a machine with 64GB of
RAM.
When booting the default PAE kernel ( 2.6.18-92.el5PAE ) that is shipped
with RHEL 5.2 installation the OS detects 64GB of RAM.
But when booting the Xen kernel ( 2.6.18-92.el5xen ) the OS detects only
14GB of the total amount of available RAM.
Did anyone encounter this problem before ?
Is it a normal

[LLVMdev] lld file format as native OS executable format
Hello,
Would it be feasible to use the internal lld file format as the native
executable format for an OS? Are there performance or space
considerations that would make this a poor choice?
Cheers,
Shea Levy

Question about DSP in Digium card
Hello.
I have a TE405P Digium Card (4 E1's) with ISDN protocol and I need to find
out if there is any limitation about DSP capabilities, I mean, I am not sure
how many phone calls my Digium card supports, simultaneously. The calling
flow goes from IAX <-> ISDN.
I am running this card into CPU like this:
- Micro PIV 3.0
- 1Gbyte Memory
Thanks.

I agree it sucks. I would switch to the only Windows player that seems to
work properly -- Foobar2000 if it offered the same sort of control/API from
external programs.

Retrieve indexes of the "first occurrence of numbers" in an effective manner
Hi,
That sounds simple but I cannot think of a really fast way of getting
the following:
c(1,1,2,2,3,3,4,4) would give c(1,3,5,7)
i.e., a function that returns the indexes of the first occurrences of numbers.
Note that numbers may have any order e.g., c(3,4,1,2,1,1,2,3,5), can
be very large, and the vectors are also very large (which prohibits
any loop).
The best I could think of is:

Two way joining vs heatmap
Hi
STATISTICA has a function called "Two-way joining" (see
http://www.statsoft.com/TEXTBOOK/stcluan.html#twotwo) and the
reference material states that this is based on the method as
published by Hartigan (found this paper:
http://www.jstor.org/pss/2284710 through wikipedia).
What is the relationship (if any) between the "heatmap" function in R
and this technique? Is there an

if/else for plot/lines?
I'm interested in writing a function that constructs a new plot on the
current graphics device if no plot exists there yet, but adds lines to
the existing plot if a plot is already there. How can I do this? It
seems to me that the exists() function might be co-opted to do this, but
it's not obvious how.
Many thanks,

[Bridge] Bridge MAC address
Sorry, if this question has been answered before, but I could not find
out with a brief look.
How can I set the MAC address for a bridge? The MAC address given for
the bridge device seems to be the one it sends network packets with if
the bridge device has an IP address set. Apparently the bridge starts
with a zero MAC address and when the first interface is attached to
it, it takes its MAC

The internal lld file format is an _intermediate_ data structure designed to make creating the final executable straightforward and fast. It isn't designed to be an executable format itself.

Finding (swapped) repetitions of numbers pairs across two columns
Hi,
I've had this problem for a while and tackled it is a quite dirty way
so I'm wondering is a better solution exists:
If we have two vectors:
v1 = c(0,1,2,3,4)
v2 = c(5,3,2,1,0)
How to remove one instance of the "3,1" / "1,3" double?
At the moment I'm using the following solution, which is quite horrible:
v1 = c(0,1,2,3,4)
v2 = c(5,3,2,1,0)
