how does one apply Western Electric / AT&T rules to R plots?
I have searched for info on how to apply the Western Electric rules for
process control, to data and plots I have in R, but I have not been able
to learn how.
Any help would be greatly appreciated.
Thank you,

custom iptables chain jumping
Hi all,
When we create a custom chain in iptables, should we specifically create a
rule to 'jump back' to the previous chain?
For example:
iptables -A INPUT -j CUSTOMCHAIN
iptables -A CUSTOMCHAIN rule1
iptables -A CUSTOMCHAIN rule2
Should we add:
iptables -A CUSTOMCHAIN -j INPUT ? Or, it will automatically go back to CHAIN
when there's no more rule?
Thank you very much,

Multiset Permutations
Dear R users,
I want to perform an exact permutation of multisets. I have looked at the
coin package, but it doesn't seem to offer what I am looking for. I want to
perform permutations (exact - without duplications) on multisets of scalars
(e.g., the multiset 0,0,1,2,2). I want to output all the possible
permutations into a data frame so that each multiset permutation occupies a
row (or

generate combination multiset (set with repetition)
Hi,
This has been asked before but not sufficiently answered from what I
could find. How do you create combinations
with repetitions (multisets) in R?
If I have
> set <- array(1:3)
And I want to choose all combinations of picking 2 numbers, I want to
get a print out like
[,1] [,2]
[1,] 1 1
[2,] 1 2
[3,] 1 3
[4,] 2 2
[5,] 2 3
[6,] 3 3

New package: sets
Dear useRs,
The new 'sets' package made it to CRAN, supporting:
o data structures for sets, fuzzy sets, multisets, and fuzzy multisets
o the use of (most) R objects as elements
o standard set operations (union, intersection, complement, Cartesian
product, power set, ...)
o support for several fuzzy logic systems
An introductory vignette is also available.
David and Kurt.

R, VR, and Debian
Hi Folks,
A while ago (September 2007) I set up an experimental
Debian 4.0 Etch installation, and installed R on it,
along with several packages -- including e1071 and
the "Bundle" VR -- by means of the Debian package
manager. Most of the time, R works fine. But not always.
Just now, I wanted to try the code suggested by
Johannes H?sing for "Stroparia"'s Multiset

Need help imputing missing data using mice and outputting them
Hello!
I am trying to impute missing data and output the results of the imputation.
My data set is called: MyData.
I have a bunch of variables all of which start with Q20_ - and some of them have missing values.
Here is what I've been doing:

Substituting inside expression
I am having following problem:
I?m constructing model for calculation of area of triangle.
I know sides a, b, and gamma angle.
I wish to calculate the area using heron?s formula:
S <- sqrt(s*(s-a)*(s-b)*(s-c))
where
s <- (a+b+c)/2
and c is calculated using law of cosines:
c <- sqrt(a^2 + b^2 -2*a*b*cos(gamma))

How can I draw a line in empirical distribution function?
I've got the graphic with this:
a=c(120,40,75,85,55,75,55,90,90,55,155)
plot(ecdf(a))
How can I draw lines to show the lower quatile and upper quartil?
I only know there is the argument lines(),
but I don't know how to use it

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

How to optimize function parameters?
Hi,
I have a dataset and I want to fit a function to it.
The function is variogram model (http://en.wikipedia.org/wiki/Variogram)
The variogram model is defined by three parameters and I want them to be
automatically optimized for real time data.
I tried to use gafit {gafit} for this, but there are some data
configuration, where optimal results given by gafit() are negative, which is
not correct

suggestion for "sets" tools upgrade
First, let me apologize in advance if this is the wrong place to submit
a suggestion for a change to functions in the base-R package. It never
really occurred to me that I'd have an idea worthy of such a change.
My idea is to provide an upgrade to all the "sets" tools (intersect,
union, setdiff, setequal) that allows the user to apply them in a
strictly algebraic style.

Generating unique permutations of a vector
Hi all,
I try to generate sets of strategies that contain probability
distributions for a defined number of elements, e.g. imagine an
animal that can produce 5 different types of offspring and I want to
figure out which percentage of each type it should produce in order to
maximize its fitness. In order to do so, I need to calculate the fitness
for all potential strategies. As an example, if I
