R Users and Developers, Plans are being made to hold the first North American useR! will be held at Iowa State University, Ames, Iowa, August 8?10, 2007, which will be a week after JSM'07. This follows successful meetings in Vienna, Austria, in 2006 and 2004, and also Directions in Statistical Computing (DSC) meetings in Auckland, NZ (Feb 2007), Seattle (2005), and Vienna (1999, 2001, 2003).

Like this? # example using qplot library(ggplot2) meanprice <- tapply(diamonds$price, diamonds$cut, mean);meanprice cut <- factor(levels(diamonds$cut), levels = levels(diamonds$cut)) qplot(cut, meanprice, geom="bar", stat="identity", fill = I("grey50")) dev.new() # create a new graph to compare with qplot # Example using ggplot ggdata <-

Hello, everyone! Does anyone know how make some symbols have special means in R? For example, we know that "+" in R means the sum of the two operand on its left and right. I want to define some operators in R by myself. Is this possible? Regards! -- Chuanlong Du Department of Statistcis Iowa State University Ames, IA, US 50011 [[alternative HTML version deleted]]

I'm using the function htmlParse() in the XML package, and I need a little bit help on error handling while parsing an HTML page. So far I can use either the default way: # error = xmlErrorCumulator(), by default library(XML) doc = htmlParse("http://www.public.iastate.edu/~pdixon/stat500/") # the error message is: # htmlParseStartTag: invalid element name or the tryCatch()

I downloaded the latest version of R (1.5.0) and issued a read.table() command that used to work with (1.3.1). Unfortunately I erased 1.3.1 from my hard drive after I downloaded R 1.5.0. Here's the command and the error message I get under 1.5.0: > golub1<-read.table("C:/Microarrays/code/data_set_ALL_AML_train.txt",sep="\t",q

I hope that Marc doesn't mind, but I felt that part of his recent post was important enough to deserve it's own subject line rather then being lost in a 60-msg-long thread...

Hello! Does any one know how to modify attributes of files (hide, read only and etc) in Windows Systems using R? I tried to use shell to call system command, but it seems that it doesn't work well. Sometimes it works but sometimes not. Regards! -- Chuanlong Du Department of Statistcis Iowa State University Ames, IA, US 50011 [[alternative HTML version deleted]]

At a snail's pace I keep on translating an introduction to R into italian; I have reached the section describing the glm() function, in which some example code is presented. The very last line of code, before the beginning of the section on Poisson models is: ldp <- ld50(coef(fmp)); ldl <- ld50(coef(fmp)); c(ldp, ldl) which of course gives results 43.663 and 43.663; the correct code

Hello, I thought some of you might like to know about a GNU project that is complementary to R in some ways, namely gretl http://ricardo.ecn.wfu.edu/gretl (GNU Regression, Econometrics and Time-series Library). gretl (a library with cli and gui clients, the gui using GTK) is designed to be very user-friendly, and suitable for teaching econometrics. It has a fairly wide variety of least-squares

I'm trying to do a Windows build of Ray Brownrigg's port of the maps library, and running into some problems. There's a makefile for the shared library. I suspect that I just need to change that to get it right, and everything will build properly, but I'm running into trouble. Here's the original makefile, along with my comments about changes: >SRC= mapget.c mapproject.c

We're pleased to announce a one day course covering static and dynamic graphics using R, ggplot and GGobi. The course will be held just before the JSM, on Saturday, 28 July 2007, in Salt Lake City. The course will be presented by Dianne Cook and Hadley Wickham. In the course you will learn: * How to build presentation quality static graphics using the R package, ggplot. We will cover plot

Hi, I want using zero-inflated negative binomial regression model to classify data(a vector of data), that is I want know each observed value is more likely belong to the "zero" or "count" distribution(better with relative probability).
