Hello dear R help members (and also Yihui and Romain), There are currently 28 R bloggers (out of the 117 R-bloggers<http://www.r-bloggers.com/>I know of) that are using wordpress.com for publishing their R code (and I suspect this number will increase with time). WordPress.com doesn't support R syntax highlighting, nor can it be embedded from other services (like gist

Hello all, I came across<http://www.r-bloggers.com/performance-benefits-of-linking-r-to-multithreaded-math-libraries/> David Smith's new post Performance benefits of linking R to multithreaded math libraries<http://blog.revolutionanalytics.com/2010/06/performance-benefits-of-multithreaded-r.html> Which explains how (and why) REvolution distribution of R uses different BLAS math

Hello everyone. There is a new competition, outlined on the blog dataists<http://www.dataists.com/2010/10/using-data-tools-to-find-data-tools-the-yo-dawg-of-data-hacking/>, inviting us to analyse statistics of the use of R packages (collected from 52 R users), to create a R-package suggestion engine for ourselves. Since I noticed several bloggers already wrote about it (as I have detailed

Dear R users, I've written a loop to generate Moran's test (spdep package) on serval subsamples of a large dataset. See below a short example. My loop is working fine, however I would like to be able to store the test results as lines of a matrix, that I would latter be able to export as a dataset. My problem is that I'm not sure how I could do this using R. Any help will be much

Hi, I'm having trouble running 'lars'. When I install it I get the following warning: >install.packages('lars') Warning in install.packages("lars") : argument 'lib' is missing: using 'C:\Users\Anna\Documents/R/win-library/2.10' --- Please select a CRAN mirror for use in this session --- trying URL

Hello everyone. After some good time of work, I am proud to present: www.r-bloggers.com What is R-Bloggers.com? R-Bloggers.com hopes to serve the R community by presenting (in one place) all the new articles (posts) written (in English) about R in the "R blogosphere". How does R-Bloggers operate? This site aggregates feeds (only with permission!) from participating R blogs. The

I would like to explore dendrogam plots interactively. For example, click on a node and return information about all of the children of that node. Is there a high level wrapper for locator() or click() that will return the nearest dendrogram node on a plot? If not, is there a way to obtain the [x,y] coordinates of all the nodes on a plot? Thanks, David David J. States, M.D., Ph.D. Professor

Hello, I am trying to import an .eps file created with Adobe Illustrator and plot it in a Quartz window (I am using R 2.11.1 GUI 1.34 Leopard build 32-bit (5589) on MacOSx.5.8). I thought of using the PostScriptTrace() to convert my .eps file to RGML, and then use readPicture to plot the file, but the first step already fails (cf below). I also had a look at the add.image( ) example,

Hello, I am working under R2.11 Windows and currently I work on a big R progjet which executes different R script in a row. Every R script represents a module. As every module depends of the variables created in the modules previously executed, I want to be shure, that I don't create or change a variable in a scriptwithout being aware that this affects the results in a later executed script.

I've developed a new R debugging tool, debugR, available at http://heather.cs.ucdavis.edu/debugR.html This basically replaces my edtdbg, which I will no longer be supporting. The new tool is now decoupled from one's text editor, and has a lot more features than edtdbg did. Try it! Feedback is encouraged, of course. Norm Matloff

Dear R users, I have two data frames that consist of statistical information for most countries around the world. One dataframe consists of the latitude and longitude ("coord.csv") of each country, while the other consists of 100's of different attributes ("countryattri.csv") for each country (like, GDP, Population, etc.). The data is organized with a header and then

Dear R-community, maybe someone can help me with this: I've been using the loess() smoother for quite a while now, and for the matter of documentation I'd like to resolve the acronym LOESS. Unfortunately there's no explanation in the help file, and I didn't get anything convincing from google either. I know that the predecessor LOWESS stands for "Locally Weighted

Hello How do you compare R to SAS in terms of speed and management of large datasets? What about Revolution R? I've seen on their site, they claim that Revolution R is much faster than R and it's multithread... Can you really notice the difference?. What dissadvantage does it have? I think it's based on R 2.10. but R already issued the version 2.12 Regards What alternative

Hello dear R community, Recently, the wonderful people<http://www.warwick.ac.uk/statsdept/useR-2011/index.html#About>behind useR!2011 made sure to nudge the speakers to send in their slides from the conference, and updated the conference's website with links to the slides (and videos)<http://www.warwick.ac.uk/statsdept/user-2011/schedule/index.html>of the talks.

A new version of the ggplot2 web application is available at http://www.yeroon.net/ggplot2. New features include 1D geom?s (histogram,?density, freqpoly), syntax mode (by clicking the tiny arrow at the?bottom), and some additional facet options. Furthermore some minor?improvements and fixes, most notably for Internet Explorer. As usual, a little demo video that shows how to use the new features:

Hello everyone Can you please teach me how to save my homework as .R file? I write my code in RGui. When I tried to save my work, the RGui only allows me to save it as .RData. By the way, after I save my work as .RData, I cannot reopen it. when I open it, only one message comes out as following: "ARGUMENT_ignored_." -- View this message in context:

dear R users, I have troubles performing Moran.I test as suggested on http://www.ats.ucla.edu/stat/r/faq/morans_i.htm my spatial data are longitude and lattitide of communities.

I want to do "moran's I test" in R language. I try to use "gearymoran" in Package "ade4","moran" in Package "spdep", and Moran.I in Package "ape". But I do not know how to do it because data format is different. My data: x y dbh 111.03 10.7 7 118.11 0.28 1.2 165.36 0.36 8.4

Hi, I read somewhere that when carrying out geostatistical analysis in R you should not use latitude and longitude...can anyone expand on this a little for me, and what would be the best coordinate system to use? I have my data in a geographic coordinate system, WGS84, decimal degrees....is this the wrong format for such analyses? I have also converted my data in the UTM projection and so have

Hi Are there any more efficient ways of calculating the neighbourhood object for large datasets? I am trying to compute Moran I statistics for a very large data set (over 14,000 points). I have been using moran.test from the spdep package and everything works fine for a small data set (200 points). However, applying the same script to the whole dataset is taking days to compute (it so far has
