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 unde...

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, Austin H.

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. Lutz

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.

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. Jason

On the Use of the nnet Library

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!

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...

When I run a fairly elementary function ("f") on the matrix outside the class it runs instantaneously (elapsed system.time = 0) but when I setMethod "f" on myClass -- returning an instance of myClass -- it...

Enlightenment and CentOS 6.5

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 Wade Wall [[alternative HTML version deleted]]
