Dear R Community, I am pleased to announce 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.

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, available on www

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. Jones Department of

Ajay, thank you very much for picking up that age-old 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

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); #fraction remaining - dt = elapsed time from

Hi, we are about to update some class definitions in our distrXXX family of packages, so I would be eager to know whether there are plans in R Core to implement some version management tools for S4 classes as described in section 7.4 in JMC's "Green Book". In his recent book (continuing the color scheme, is it to be called the "Yellow Book"? :-), this topic has not been

I am discovering sapply! :-) Could you please help me with a very elementary question? Here is what I know. The following two programs generate the same answer. --------------------------------+---------------------------------------- Loops version | sapply version --------------------------------+----------------------------------------

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

x86 snv 108 I have a pool with 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 -------------- next part --------------

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

Dear List, I am trying to solve a problem by the neural network method(library: nnet). The problem is to express Weight in terms of Age , Sex and Height for twenty people. The data frame consists of 20 observations with four variables: Sex, Age, Height and Weight. Sex is treated as a factor, Age and Weight are variables normalized to unity, as usual. I wanted to construct a neural network, and so

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

Dear LLVM contributors, I am Naoki Shibata, an associate professor at Nara Institute of Science and Technology. I and Hal 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,

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 system.time = 0) but when I setMethod "f" on myClass -- returning an instance of myClass -- it runs perceptibly slower (elapsed system.time = .06). I

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! Jeff

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

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
