Maintaining specific order when using aggregate or change order on axis
Hi All,
I'm using the following code to produce some stacked bar graphs.
*setwd("C:\\Users\\Tinus\\Documents\\NMMU\\R\\Seamounts")*
*SChla <- read.csv("SM_Chla_data.csv")*
*
*
*#Extract mean values from data file*
*
*
*Coral <- SChla[185:223,] #Reduce SChla to Coral only*
*coral <- with(Coral , aggregate(cbind(Pico, Nano, Micro),
list(Depth),FUN=mean))*

Incorrectness of mean()
I have found following problem:
I have a vector:
> a <- c(1.04,1.04,1.05,1.04,1.04)
I want a mean of this vector:
> mean(a)
[1] 1.042
which is correct, but:
> mean(1.04,1.04,1.05,1.04,1.04)
[1] 1.04
gives an incorrect value.
how is this possible?
thanks,
zbynek

classifying packets and ports
Hi,
I''ve been working for a big corporate company as junior system engineer and
getting nicely to understand HTB/iproute2/iptables etc,
The ordinary users(about 500 users), can pop / smtp / skype out on the
network, but I can''t ssh out, cause they blocked the ports. Thought of being
clever, I let my home linux listen on port 443 or 110 for ssh connection,
but it wont connect, I

problem with classifying
Hello list
I have a problem with classifying traffic from two providers, and about
600 users.
I have the following situation:
P1-\ | linux |
--eth0-| box |-eth1
P2-/ | |
P1 and P2 are coming from VLANs. I have 4 type traffic which I want to
classify.
The traffic is divided as follows:
P1 - 100mbit from realm 0x70000
10mbit from realm ! 0x70000

classifying packets
hello!
i have the following problem:
i have a pc, which has one (eth0) NIC. eth0 is connected to two other linux
machines acting as routers to the internet.
i want to classify packets outgoing from my PC. i want to mark packets that are
routed through 1. router with mark 1 and the others packets routed throuhg
router 2. with mark 2.
i had following ideas:

[LLVMdev] Classifying Operands & Def/Use Chains
Is there any way to discover whether a particular operand of a MachineInst
participates in addressing? That is, if the MachineInst references memory,
can I tell, given an operand, whether that operand is part of the address
calculation for the instruction?
Also, is there any reasonable way to get the set of machine instructions to
which the output(s) of some machine instruction flows? The

Classifying values in vector
I have a vector of size 217 called "A".
the values of A are not sorted and range from 0 to 1 (normalized)
I am having difficulty writing a program to create a new vector "B" where
if A's value is 0< A <=0.333 then B is 0
if A's value is 0.333< A <=0.666 then B is 1
if A's value is 0.666< A <=1 then B is 2
so if A is

samba-ad-dc. It is called by the server.

Classifying boolean values
Hi to all, I'm new to this forum and new to R. I have to build a tree
classifier that has boolean values as response.
When I build the tree with:
echoknn.tree <- tree(class ~ ., data=echoknn.train)
where "class" is a coloumn of my dataset (echoknn.train) of boolean values,
the result is a tree where leaf nodes are numbers in the range [0,1]; but
this isn't the result that I

Extract p-value from aftreg object
Dear all,
does anyone know how I can extract specific p-values for covariates
from an aftreg object? After fitting a model with aftreg I can find
all different variables by using str(), but there's no place where
p-values are kept. The odd thing is that print() displays them
correctly.
EXAMPLE:

Classifying Intertwined Spirals
I'm using an SVM as I've seen a paper that reported extremely good
results. I'm not having such luck. I'm also interested in ideas for
other approaches to the problem that can also be applied to general
problems (no assuming that we're looking for spirals).
Here is my code:

library(e1071)
raw <- mlbench.spirals(194, 2)

grouping or classifying servers
hi list,
first of all, i''m new to puppet, and i''m evaluating it right now since
a few days in my company ( internet, books, etc as sources ).
i''ve been using cfengine for a few years now, and trying to get into
puppet.
i''d install puppet 0.25, because i feel a need to use regular
expressions to identify nodes

Classifying large text corpora using R
Dear everyone,
I am new to R, and I am looking at doing text classification on a huge
collection of documents (>500,000) which are distributed among 300 classes
(so basically, this is my training data). Would someone please be kind
enough to let me know about the R packages to use and their scalability
(time and space)?
I am very new to R and do not know of the right packages to use. I

Classifying values by interval
Greetings All!
As is often the case on this list, the answer may well
be under my nose but I can't see it!
I am looking for a "smart" way to do the following.
Say I have a vector of values, X. I set up bins" for X,
say with breaks at B = c(b1,b2,...,b11) covering the
range of X, i.e. bins numbered 1:10. The value x is in
bin i if B[i] < x <= B[i+1]
What I seek is a

tip: large plots
Hi all,
I'm working with a bunch of large graphs, and stumbled across
something useful. Probably many of you know this, but I didn't and so
others might benefit.
Using pch="." speeds up plotting considerably over using symbols.
> x <- runif(1000000)
> y <- runif(1000000)
> system.time(plot(x, y, pch="."))
