I am thinking about adding several geom and stat extensions to ggplot2 in the Hmisc package. To do this requires using non-exported ggplot2 functions as discussed in http://stackoverflow.com/questions/18108406/creating-a-custom-stat-object-in-ggplot2 If I use the needed ggplot2::: notation the package will no longer pass CRAN checks. Does anyone know of a solution? I'm assuming that

Hello Everyone,   I have just started learning R and am in the process of figuring out what it can and can't do. I must say I am very impressed with R so far and am amazed that something this good can actually be free.   Recently, I finished reading R for SAS and SPSS Users and have begun reading SAS and R and Data Manipulation with R. Based on what I've read in these books and elsewhere,

Dear all, There have been a variety of discussions on the R list regarding the use of R in clinical trials. The following post from the STATA list provides an interesting opinion regarding why SAS remains so popular in this arena: http://www.stata.com/statalist/archive/2008-01/msg00098.html Regards, -Cody Hamilton

Frank (or anyone else), can you offer any comments comparing runjags, R2jags, rjags ? I couldn't find any vignettes, nothing except a brief mention on Task Views.

Hi all, I'd like to use the Hmisc::summarize function, but it uses a function (FUN) of a single vector argument to create the statistical summaries. Consider an easy case: I'd like to compute the correlation between two variables in my dataframe, grouped according to other variables in the same dataframe. For exemple, consider the following dataframe D: V1 V2 V3 A 1 -1 A 1

The international R User Conference useR! 2012 will be held June 12-15 at Vanderbilt University in Nashville, Tennessee, USA, with a pre-conference full-day course offered on June 11. Participants are encouraged to submit a one-page abstract for oral or poster presentation at the conference. Half-day tutorials will be held in the morning and afternoon of June 12th. For tutorials, please

Dear Group, I have made significant improvements to our Sweave template, have made the template self-contained (i.e., you can run it yourself and it will find the datasets it needs), and have included the output pdf file. This is at http://biostat.mc.vanderbilt.edu/SweaveTemplate . You will see in the pdf file the enhancements in how R code is pretty-printed, and I have added an example

I would appreciate getting a clarification of /usr/lib/R/library vs /usr/local/lib/R/site-library. I am running R 1.8 on Debian Linux. On one occasion doing update.packages() resulted in versions of one or more libraries being placed in one of these directories without removing the old version, and the old version took precedence over the new. I'm sorry I did not save the steps I used. I

I have not been able to figure out the format for specifying limits, at, labels in scales <- list(relation='free', limits=..., at=..., labels=...) when there is more than one paneling variable, e.g., xyplot(y ~ x | a*b). Thanks for any guidance. Frank ----- Frank Harrell Department of Biostatistics, Vanderbilt University -- View this message in context:

In Henric's recent post, he included this output: @BOOK{R:Harrell:2001, AUTHOR = {Frank E. Harrell}, TITLE = {Regression Modeling Strategies, with Applications to Linear Models, Survival Analysis and Logistic Regression}, PUBLISHER = {Springer}, YEAR = 2001, NOTE = {ISBN 0-387-95232-2}, URL =

I would like to add auxiliary information to the bottom of two strips on each panel that comes from a table look-up using the values of two variables that define the panel. For example I might panel on sex and race, showing 3 randomly chosen time series in each panel and want to add (n=100) in the bottom strip to indicate the 3 curves were sampled from 100. Is there a not-too-hard way to do

Dear Colleagues: In producing a book or a handout I sometimes cut out a large part of the printed output of an R function, substituting ... for that chunk. Deleting non-essential output saves paper. It would be nice to have a capability in Sweave to allow the user to specify a starting and an ending regular expression that would identify consecutive lines of output to replace with ...,

Does anyone know of R functions for doing composite quantile regression (Hou and Yuan Ann Stat 36:1108, 2008)? The paper's authors do not talk about software in their paper or on their web sites.

I know you can control this with the cairo package, but I was hoping that embedFonts( ) would provide a way to embed all fonts, not just the non-standard ones. I'm submitting graphics to a journal that wants Helvetica and Helvetica-bold embedded for some reason. Is there an easy way to do this on a pdf graphic created wit pdf()? A linux system command would be excellent for my purpose.

Dear Colleagues: I would like to write a front end for a modeling function, but run into trouble when passing a weights argument. y <- 1:5 x <- c(1,3,2,5,4) w <- function(formula, ...) lm(formula, ...) lm(y ~ x, weights=c(1,1,1,2,2)) w(y ~ x) w(y ~ x, weights=c(1,1,1,2,2)) Error in eval(expr, envir, enclos) : ..1 used in an incorrect context, no ... to look in w <-

Well, I agree that plots with multiple y-axes can be very confusing but .... i am not sure that always they are also misleading .... One time i was asked to make a 2 y-axes plot, one y axes was for elevation (heights in meters) and one for rugosity (values between 1 and 2 - unitless). The idea was to visualize that for a more complex profile the rugosity is higher than for a flatter terrain. A
