prob package: elementary probability on finite sample spaces

...nnounce the beta-release of the prob package. The
source code is now on CRAN, and binaries should be generated there
before long. In the meantime, you can get it with
install.packages("prob", repos = "http://r-forge.r-project.org")
The prob package gives a framework for doing elementary probability on
finite sample spaces in R. The primary notion of "probability space"
has been built around the data frame structure, both for simplicity
and to maximize compatibility with the R Commander by John Fox.
The package addresses an ample proportion of material in a typical

elementary statistics with R (rkward?)

Hi, I am trying to learn some basic statistics stuff but I cannot find any
elementary statistics exercises using R language. Using RKward would be even
better...
I need that in analysing sociological data, obtained through questionnairres -
findind corelations between variables, relations between different types of
data, etc.
Could anyone recommend simple tutorials/exercises, avai...

Elementary Symmetric Polynomials

We are interested in obtaining an efficient function that for a given
vector of length t will output a vector of length t+1 that contains the
associated values of the elementary symmetric polynomials in t
variables. Below is what we have at the moment, but it is a little slow
for our needs. Any suggestions?
Thanks ahead of time for any help you can offer,

RE: summaries (was: SUMMARY: "elementary sapply question")

...d habit of
posting summaries.
It existed years ago on s-help and I find it is still a great
thing: I would not have bothered to read your original question
nor the answers you got, but I did read the summary -- and I
learned something quite interesting!
Maybe some others who receive multiple non-elementary answers to their
questions could sometimes bother to compile a summary so
that some of the bystanders be educated at low cost??
Unrealistic?
I'd be willing to do it for my own questions if it was at
least a little common.

Elementary question about computing confidence intervals.

I would have thought this to be relatively elementary, but I can't find it
mentioned in any of my stats texts.
Please consider the following:
library(fitdistrplus)
fp = fitdist(y,"exp");
rate = fp$estimate;
sd = fp$sd
fOneWeek = exp(-rate*7); #fraction that happens within a week - y is
measured in days
fr = exp(-rate*dt); #...

Version information for S4 classes --- elementary version management

...ackage version tag in the DESCRIPTION file.
The rationale behind this is that an updated class definition would
at least be traceable to one particular package version, while
on the other hand the package version string is not a "large" object.
Based on this package version information, (elementary)
version management could then be provided by means of
generic functions
getClassVersion() [as described in the Green Book, 7.4]
conv2NewVersion() ## by default issuing an error ("Not yet defined")
isOldVersion() ## true or false; by default NA
Defining particular methods for his class...

Elementary question - accessing feature codes from cell phone

Hi, please forgive me for this (hopefully) simple question. I cannot seem to
find an answer or solution while searching around.
I want to be able to call in to my server using my cell phone and be able to
set call forwarding for my extension and enter a phone number and also be
able to call in to that extension and disable the call forwarding. I see I
can do this through the ARI web interface

possibly a stupid question, why can I not set sharenfs="sec=krb5, rw"?

...ith around 5300 file systems called home. I can do:
zfs set sharenfs=on home
however
zfs set sharenfs="sec=krb5,rw" home
complains:
cannot set property for ''home'': ''sharenfs'' cannot be set to invalid options
I feel I must be overlooking something elementary.
Thanks, Alastair

position of an element in a vector

Hello. Sorry for the elementary post. I've looked through the
documentation, but can't seem to find a function which allows one to
extract the position of an element within a list...for example the position
of the element 4 in the vector c(1,2,4,3,6) is 3. Thanks much for any help.

On the Use of the nnet Library

...ponse analysis of this data. I
do not know an effective method to evaluate the response to
the variance of each explanatory variable. Is there such a function in
the library, nnet? Such a function may help me reduce the number of the
explanatory variables.
I wonder if anyone could help me in such elementary questions.
---- It's elementary, Watson!
I remain an obedient Watson, hoping for Holmes' wisdom.

SUMMARY: "elementary sapply question"

I am grateful to Andy Liaw, Douglas Grove, Brian Ripley, Tony Plate,
Dirk Eddelbuettel and Sundar Dorai-Raj all of whom got together and
drilled sense into my skull. I would like to take some effort into
explaining what the question was, that I was grappling with, and the
(nice) R way of solving the question.
My apologies: I am still a victim of too many years of writing C, so
I'm a bit dense

RFC: SIMD math-function library

...l Finkel would like to jointly propose to add my vectorized math
library to LLVM.
The library has been available as public domain software for years, I am
going to double-license the library if necessary.
********
Below is a proposal to add my vectorized math library, SLEEF [1], for
evaluating elementary functions (trigonometry, log, exp, etc.) to LLVM.
The library can be used directly, or can be targeted by an
autovectorization infrastructure. Patches to tie SLEEF into LLVM's
autovectorizer have been developed by Hal Finkel as part of the bgclang
project (which provides LLVM/Clang ported t...

S4 method execution time

Hello:
I have written some an elementary S4 classes around a matrix to strengthen
control of some key attributes. When I run a fairly elementary function
("f") on the matrix outside the class it runs instantaneously (elapsed

instance of myClass -- it...

Enlightenment and CentOS 6.5

Good morning,
I've been looking around for binaries for Enlightenment (>= 0.17) for
CentOS 6.5. I've found something called "elementary" from OpenSUSE but
I'm not sure what Elementary really is :) Any suggestions?
Thanks!

Elementary questions about data structures

Folks,
S_t = (x_t, y_t) is the state of a system at time t. There is an
iterative function which converts S_t into S_{t+1}. I can easily write
this in R like this:
iterate <- function(S) {
list(S$x+1, S$y+1)
}
So this function eats S_t and makes S_{t+1} and I can say
S2 <- iterate(S1)
My question: suppose I want to iterate from 1..10, what is the data
structure

Naming list objects

Hi all,
I am trying to name list objects, but am having trouble doing so. At the
moment I have list alninc that has 3 objects and I can refer to them as
alninc[[1]] . . .alninc[[3]]. I would like to refer to them as alninc$F,
alninc$V and alninc$G. How do I do this? This appears to be an elementary
question, but I can't find the solution anywhere.
Thanks

Just to be precise, copy-on-write is an optimization widely deployed
in most modern *nixes, particularly for the architectures in which R
usually runs. But it is not an elementary property; it is not even
possible without an MMU.
