similar to: Expressions returned by a Package function

Hello, (Sorry for the repost, i am resending in plain text) I have a function 'ewrap' (see below for definition). It takes 3 expressions and returns another expression e.g. map <- ewrap({ len <- length(r$addon) rhcollect(len,1) }) becomes: expression({ NULL result <- mapply(function(.index, k, r) { { len <- length(r$addon)

Greetings, I would like to announce the 0.1 release of RHIPE:R and Hadoop Integrated Processing Environment. The website is located at : http://www.stat.purdue.edu/~sguha/rhipe<http://www.stat.purdue.edu/%7Esguha/rhipe>. The download link is the bottom most link on left side of the page. RHIPE works on top of Hadoop, providing the R user a way to distribute commands over the Hadoop

Hi r-help forum, I have been collecting contact data (with proximity logger collars) between a few different species of animal. All animals wear the collars, and any contact between the animals should be detected and recorded by both collars. However, this isn't always the case and more contacts may be recorded on one collar of the two. This is fine, it depends on battery life and other

Coming off of xen environment; still testing with kvm, just a few questions: 1. What is the roadmap for release of qemu-kvm 1.1 and libvirt 0.10.2 for el6, cause I had to compile from upstream to get the latest stuff. 2. Should not virt-manager show the sparsed disk size instead of actual reserved size of a vm? 3. Where is the virsh bash_completion conf.d file from upstream; since el6 rpm

Hi R forum, Each row of my data (below) show a new contact event between animals. In order to ultimately look at the patterns of intervals between contacts, I need to calculate a contact end time. The contact starts at the date and time shown in V4 and V5, and lasts for the duration shown IN SECONDS in V6: > data2<- read.csv(file=file.choose(), header=F, sep=" ") >

Hello, We have created an interface between R and Hadoop so that the user can, after a fashion, interact with very large datasets using the Map Reduce programming model. We also use IBM's TSpaces to implement a shared memory implementation that can be accessed via R(somewhat like networkspaces). RHIPE uses Rserve to execute R code. Some of the functions implemented are: mrlapply - run

I am a beginner with R. After I installed R 2.8.0, I tried to add a package. R CMD INSTALL RHIPE.tar.gz I got following error message: cannot extract package from RHIPE.tar.gz Can anyone tell me what's the problem? -- Best Regards, Zihang Yin 919-225-1717 Computer Science Duke University

dear all, I'm a newbie in map tools. I was asking to perform an apparently very simple task. I have a list of countries (about fifty all over in the world) scored with a real positive value. Eg Country score Italy .56 UK .58 Korea .41 Mexico .63 ... I wish to plot geographical maps where every country is filled with a color depending on his score. Using maptools library and

I'm having difficulty overlaying maps when writing to a file graphics device. My command sequence has the structure plot(map1) par(new = T) plot(map2) On the screen device, it works fine. When I attempt something like png(file = "map.png") plot(map1) par(new = T) plot(map2) dev.off() only the last map appears, the previous ones having been cleared. Can someone clarify? Thanks,

Hi I'm trying to measure the effect of a policy intervention (Box and Tiao, 1975). This query has to do with the coding of the model rather than with the particulars of my dataset, so I'm not providing the actual dataset (or a simulated one) in this case, apart from some general description. The time series are of length n=34 (annual observations between 1977 and 2010). The policy

Hello, I had been using R for text mining already. I wanted to use R for large scale text processing and for experiments with topic modeling. I started reading tutorials and working on some of those. I will now put down my understanding of each of the tools: 1) R text mining toolbox: Meant for local (client side) text processing and it uses the XML library 2) Hive: Hadoop interative, provides the

Hello! I have 2 maps - both created in ssplot and both identical in terms of outline. Is there any way to superimpose Map1 (which has black borders between Canadian provinces) onto Map2 (which is also a map of Canada)? Thanks a lot for your hints! Dimitri ### A.

I write about R every weekday at the Revolutions blog: http://blog.revolutionanalytics.com and every month I post a summary of articles from the previous month of particular interest to readers of r-help.

True only if any earlier filter also passed in an empty map. Maybe it's worth explicitly mentioning that

Right now the functionality is available, sometimes, from the C standard library. But embedded environments (often running a limited standard library) and server environments would benefit heavily from a standard way to specify context switches within a single thread in the style of makecontext/swapcontext/setcontext, and built-in support for these operations would also open the way for

Always hard to tell if THIS is a homework project. As with most things in R, if you can not find at least a dozen ways to do it, it is not worth doing. The question (way below) was how to take two vectors of length two and make a longer results based on using the ":" operator to generate a range between the first element of each array and then between the second elements and return the
