R Graph Gallery : categorization of the graphs
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 -

Hosting a R Graph Gallery?
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

How to configure ess-5.2.0beta3-1.i586.rpm, Xemacs and SuSE 9.0?
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

par() in .Rprofile
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

Looking for help in calculating percentiles
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?

Add item to scale?
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.

Graphical table in R
I would like R to produce some tabulated data in a graphical output. When I say tabulated data, what I mean is a table with rows and columns. This would be useful when reading in a big file, performing some analysis on it, and then wanting to display the results as a table. Something like plot(x,...) where x is a matrix For example, the result could look (approximatly) like...

mailing list for basic questions - preliminary sum up
Dear R-user, I already received quite a lot of replies to this mail and like to do a preliminary sum up. A few were sceptical about the use of such a beginner mailing list. The arguments were that people starting with R will only stay subscribed for a short time until they reached the R-help "level" and therefore only beginner will teach beginner how to use R. But as far

R and mysql on debian
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?

arima() in for loop
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

Multiple colors in plots/lookup function
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

Rtips (was Re: ? building a database with a the great /cookbook
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 >

unix environment variables under R
hi, i am working on a little R-project with a couple od other guys.we use CVS, but everyone keeps the R-source files in different locations in his home-directory. of course this causes trouble when sourcing R-files. i thought a UNIX environment variable could be the solution, but R doesn't seem to know about the environment variables. e.g. >> source("$PROJECT/xxx.R")

R and databases - a comment
1. That was a part of a private email exchange. It has been suggested that more people may be interested. 2. I did use various databases (significant part of my job) for the last 15 years. Some with R for the last 3 years as a hobby. Some comments on the ones used below. Sorry, no links - I am time-constrained at the moment - please google if interested in details. The remarks are from the point
