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 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

JAVA_HOME is unset by default on my system. As suggested, by Godmar Back, on the list I've tried setting it. The Gentoo way is to use JAVA_HOME=$(java-config --jdk-home) and this produces what I think is the desired result #printenv | grep -i JAVA_HOME JAVA_HOME=/opt/sun-jdk-1.6.0.20 BUT # env JAVA_HOME=/opt/sun-jdk-1.6.0.20/ R CMD javareconf *** JAVA_HOME...

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
