Hello all, This is to announce the creation of R-sig-wiki, a new R SIG (Special Interest Group) mailing list dedicated to the elaboration and maintenance of a R Wiki. You can subscribe at: https://stat.ethz.ch/mailman/listinfo/r-sig-wiki. There is currently a prototype for a new R Wiki at http://www.sciviews.org/_rgui/wiki (temporary address). The main idea is to offer a site where users

Frank uses the term "hierarchical keyword organization" which I agree is a good way to organize a system designed to help users. In fact, this is one reason why I like the R graphics gallery which allows one to quickly find a particular type of plot based on keyword, examine the plot to see if it's close to what's desired, and then get the detailed code to examine or modify for

For me as a beginner a cookbook would be welcome. so many great code examples are posted into the help list, but finding these is quite difficult. I think it comes all down to the problem who is compiling / contributing and can judge what should go in. In this respect, Detlef Steuer (suggestion , might be a solution http://fawn.unibw-hamburg.de/cgi-bin/Rwiki.pl?RwikiHome. Frank >

Dear R users, Following some of the recent questions and discussions about the R plotting abilities, it occurred to me again that it would be very valuable to have an R graph gallery. Eric Lecoutre made a very nice example in: http://www.stat.ucl.ac.be/ISpersonnel/lecoutre/stats/fichiers/_gallery.pdf It would be very useful to many beginners, but probably also advanced users of R, to have an

I'm trying to get R and ESS to work with Xemacs on a newly installed SuSE 9.0 system. Is some setup required beyond installing the rpms? I've installed the Xemacs packages from SuSE xemacs-info-21.4.13-35 xemacs-packages-el-20030629-37 xemacs-21.4.13-35 xemacs-el-21.4.13-35 xemacs-packages-info-20030629-37 xemacs-packages-20030629-37 ess-5.2.0beta3-1.i586.rpm

Dear all I installed new version (from binaries) and I noticed that par(bg="white") which I have in my .Rprofile causes error message on startup But if I issued this command immediately after startup everything worked as expected. I did not see any note in changes file or elsewhere. Should I specify white background in .Rprofile differently? Or is there some other recommended way

(R-1.6.0 and chron 2.2, linux) I have to work with date/time values from another LOCALE on my machine. My normal locale is "de DE at euro" and the data I have to handle use AM/PM specifications for the times. dstring <- "Nov 12 2001 4:31PM" The problem now is, that strptime(dstring, "%b %d %Y %I:%M%p") [1] "2001-11-12 04:31:00" just ignores my

Hi, many thanks for all suggestions as to shading of areas. Now to another small detail: how do I add items to the x-axis? Given a plot of "dnorm", I'd like to add some text to the x-axis, preferably with a corresponding tick mark. Imagine the typical \lambda demarcating a tail area. So far, I've only been able to add text in the plot region, not in the one of the axes.

Hi All: I am working with a dataset on Arsenic toxicity, and I am trying to calculate the 20th, 40th, 60th, 80th, and highest percentiles for a variable, dietary Moisture (variable name dMoist). The inbuilt function quantile(dMoist) would print 0, 25th, 50th, 75th, and 100th percentile. Does there exist a function that can calculate xth percentile (where x = 10th, 20th, ... etc) values?

Dear R-help, I have started using R on my Linux box (Debian), and I have some problems with setting the editor/keyboard for R. The For instance, arrow-up gives "^[[A", and delete gives "^H". I have a Norwegian keyboard, but that doesn't cause any problems for editors like emacs. Could you advice me on how I can set the editor for R right? I have tried

Hello, I have been using RODBC on Windows with version 1.41 of R successfully, connecting to a mysql database using MyODBC. Now I would like to do so with R under Debian/GNU Linux. I just tried RMySQL (install failed, since mysql libraries were not found), DBI (no MySQL driver available) and I can't find the RODBC package any more on CRAN. Any suggestions? Johannes Ranke P.S.: Thanks for

It seems to be the time of the year for top 10 lists both looking backwards (e.g. films: http://www.msnbc.msn.com/id/3660638/ ) and forwards (e.g. trends: http://www.wfs.org/forecasts.htm ) In this light I think we need a list of the top 10 features that users think R needs. Some of these are concrete while others are vague. By R, I am referring to the entire R system including packages, not

I feel that as long as people continue to provide help on r-help wikis will not be successful. I think we need to move to a central wiki or discussion board and to move away from e-mail. People are extremely helpful but e-mail seems to be to always be memory-less and messages get too long without factorization of old text. R-help is now too active and too many new users are asking

Hello all, I want to read a table from a given web page. If I do something like > str="http://www...." # this is the web address > aux1 <- url(str,open="rt")# open connection > aux2 <- readLines(aux1) # read web page aux2 contains the html file. I want to extract the table from the html file. Is there a function html2R, the opposite of R2html?

Hello all, It seems that the next improvement to the R Graph Gallery is categorization of the graphics, that way each graph will be easier to find. That step should be done *carefully* if we want to avoid the opposite side-effect : graph not reachable through the categories. That's why the wisdom of the R community is required. Graphics will be classified in : - categories -

hi all, In a simulation context I'm running in a for loop the arima() function for( i in 1:1000){ y<-arima.sim(....) out<-arima(y,....) ........ } Everything works, but after some cycle (10, say) I get error due to the particular y-values simulated. (E.g., a *frequent* error is "Error in svd(na.omit(xreg)) : 0 extent dimensions") As a

Hello, I'd like to do something like: n<-100 zz<-cbind(rnorm(n),rnorm(n),floor(runif(n)*3+1)) colors<-c("red","green","blue") plot(zz,col=colors(zz[3])) and have a matrix of scatterplots colored by class. The above does not work, of course, but I'm not sure exactly what function I'm looking for. Thank you for your time, Dave, -- Dave

Hi, Since I started to make some 'final' plots of my data I found that I have tons of questions related to 'the little things'. Rather than bother the list with all the questions (ahem), or search the archives for similar questions and translate the context, I would like to find a FAQ for plotting in particular (and R programming in general). I know for sure (searching the

As an R absolute beginner and an expert (very old) statistician and latex user, I'm interested in using R to produce AUTOMAGICALLY tables in latex format. I mean I would like to have the means to build an R procedure generating **FROM INSIDE** a table or a graph to be inserted directly into latex. I've read http://hesweb1.med.virginia.edu/biostat/s/doc/summary.pdf where the author speaks
