Hi, is there a simpler way to count the number of elements in a vector that are not NA than this: countN <- function (v) { return (Reduce(function (x, y) x + y, ifelse(is.na(v), 0, 1))) } ? - Godmar

Hi, I am trying to use R for some survey analysis, and need to compute the significance of some correlations. I read the man pages for cor and cor.test, but I am confused about - whether these functions are intended to work the same way - about how these functions handle NA values - whether cor.test supports 'use = complete.obs'. Some example output may explain why I am confused:

Hi, I am confused about how to select elements from a list. I'm trying to select all rows of a table 'crossRsorted' such that the mean of a related vector is > 0. The related vector is accessible as a list element l[[i]] where i is the row index. I thought this would work: > crossRsorted[mean(q[[ crossRsorted[,1] ]], na.rm = TRUE) > 0, ] Error in q[[crossRsorted[, 1]]] :

Hi, I'm new to R and would like to know, how one can populate the list with array data. I'm reading a tab separated table in R. The data in the table looks something like this. #Table Data Comp    A    B    C Extracellular    103    268    535759 Nucleus    45603    47783    442744 #R code myData <- read.table("table.data",                 header=T,

Dear Person That Posted This Email, Please be aware that calls for papers are only on-topic for this email list if they are specifically about LLVM. For example, a call for a workshop on LLVM in Scientific Computing would be on topic whereas a general compiler call for papers (like the one below) is not. That said, I hope you receive many strong submissions. Your conference looks

Hi - I have attempted to use the fork::fork() function to perform parallel processing. However, the child R function called needs to know a given set of parameters to complete its task. Specifically, I iterate through a vector, and output values based on the elements of that vector to a database. The output strings contain elements of the iterated vector. I mocked-up the following code as an

Using R-2.8.0 and R-2.8.1, I get behaviour like this: R version 2.8.0 (2008-10-20) Copyright (C) 2008 The R Foundation for Statistical Computing ISBN 3-900051-07-0 [....] > Sys.getenv("LD_LIBRARY_PATH") LD_LIBRARY_PATH

Installing rJava fails consistently, whether installed via the command line as below, or through "install.packages( 'rJava' )", and whether 0.84 or 0.85 is used, with the message :- "checking JNI data types... configure: error: One or more JNI types differ from the corresponding native type. You may need to use non-standard compiler flags or a different compiler in order to

Maybe there is a great website out there or white paper that discusses this but again my Google skills (or lack there of) let me down. I would like to know the best way to export several doubles from a function, where the doubles are not an array. Here is a contrived function similar to my needs: multipleoutput<-function(x) { squared<-x^2 cubed<-x^3 exponentioal<-exp(x)

Having difficulties getting rJava to install on my Debian Squeeze box. Perused the R-help list and tried some things that have worked for others but not for me. Below is the output of my attempted build, R CMD javareconf -e, and sessionInfo(). Note I tried the R CMD javareconf also as root, restarted R after each of these, all no help. * Installing *source* package ?rJava? ... checking for
