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.

hello, if i load the RSQLite package in addition to the RPostgreSQL package, i get various errors when trying to use RPostgreSQL functions. here is an example transcript showing one such error: ========================================================== R version 2.15.0 (2012-03-30) [...] > packageVersion('RPostgreSQL') [1] 0.3.2 > packageVersion('RSQLite') [1] 0.11.1

Hello R users, I am trying to make a my first package and I get an error that I can understand. The package is build out of three files (one for functions, 1 for s4 classes and 1 for s4 methods). Once I source them I run package.skeleton( name="TDC" ) within a R session and I get Creating directories ... Creating DESCRIPTION ... Creating Read-and-delete-me ... Saving functions and

Hi all,   I have loaded the LIMMA and Biobase package and tried these commands:   library(limma) library("Biobase") data <- read.table("c:/temp/data.txt",header=T,row.names=1) ExpressionData <- as.matrix(data[,c(2,3,4,6,7,8)]) eset <- new("ExpressionSet", exprs = ExpressionData) design <- cbind(WT=1,P=c(0,1,1,0,1,1),G=c(0,1,0,0,1,0)) fit <-

Two recent changes have been committed to r-devel, related to discussions on this list earlier: 1. setOldClass() has an argument prototype= to specify the default object for the class. If provided, the S3 class can be a slot in an S4 class, with a valid default object. (It's still not going to work well to have an S3 non-virtual class as a superclass of an S4 class. See the

We would like to announce the availability on CRAN of new versions of our packages "distr" (1.8), "distrEx" (0.4-4), "distrSim" (1.8), "distrTEst" (1.8), "startupmsg" (0.4) as well as a new package "distrDoc" (1.8) [all of them require R >= 2.2.0] -----------------------------------------------------------------------------------------

We would like to announce the availability on CRAN (with possibly a minor delay until on every mirror) of new versions of our packages in the "distrXXX"-family (version 1.9), i.e.; "distr", "distrEx", "distrSim", "distrTEst", and "distrDoc" as well as of package for managing startup messages, "startupmsg" (0.5).

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

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

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

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 --------------------------------+----------------------------------------

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

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

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

I have a few questions and thoughts regarding class versioning and serialized S4 class instances. How is the version argument to setClass is intended to work? It appears to want an externalptr, but that seems odd to me. setClass("FOO", representation(x="numeric"), version="1.2.3") Error in validObject(.Object) : invalid class

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
