%dopar% parallel processing experiment
dear R experts---
I am experimenting with multicore processing, so far with pretty
disappointing results. Here is my simple example:
A <- 100000
randvalues <- abs(rnorm(A))
minfn <- function( x, i ) { log(abs(x))+x^3+i/A+randvalues[i] } ?## an
arbitrary function
ARGV <- commandArgs(trailingOnly=TRUE)
if (ARGV[1] == "do-onecore") {
?library(foreach)

Using R with Hadoop/Hive for Big Data
Hive <http://hadoop.apache.org/hive/> is a data warehouse infrastructure
built on top of Hadoop that provides tools to enable easy data
summarization, adhoc querying and analysis of large datasets data stored in
Hadoop files. It provides a mechanism to put structure on this data and it
also provides a simple query language called QL which is based on SQL and
which enables users familiar with
