I installed the MinGW-5.0.0 compilers today (gcc-3.4.2 is now contained in the 'Current' distribution. When the current compilers failed to compile the referenced Matrix update and not knowing how to check the exact version numbers for individual files, I applied the Id.exe and f771.exe fixes from the 'Building R for Windows' page (http://www.murdoch-sutherland.com/Rtools/#ldbug).

Dear all, I have a question on the dose-response estimation with clustered/ correlated binary data. I would like to estimate the hit rate for a certain test at various concentration levels. The test is used on 5 subjects, and each subject is tested 20 times. If we assume that the 100 samples are independent, the hit rate estimate is unbiased, but the variance is under-estimated. The other

I'll address two issues. The first is today's error message and the other is change management for contributed packages on CRAN. TODAY'S ERROR MESSAGE I switched from the 0.995-1 versions of lme4 and Matrix to those referenced in the subject line this afternoon. Prior to using these packages on anything else, I applied them to code that 'worked' (provided numerical results

It is my understanding that Tcl/Tk does not come with the base installation of R under OS X ( http://www.sciviews.org/_rgui/projects/TclTk.html). Is there a simple way to explain how a user with limited tolerance for computer complexity can obtain and install Tcl/Tk for OS X? Thanks. Chuck Background: Roughly a third of my target audience uses OS X. I do not and I do not have access to a

1) In general, I would appreciate help in adding functions to the Rcmdr menu system. I've been able to modify the menus themselves and source test code but I can't get R functions to execute from the menu. My latest proof of concept code follows: Three lines added to "Rcmdr-menus.txt": menu junkMenu topMenu "" ""

It is frustrating to see the labels I want in the dimensions of a list but not be able to extract those labels into titles for plots generated from component objects. If someone could set me straight, I would appreciate it. For your amusement, I have provided an example of the Byzantine code I am currently using to avoid loops: # Simulate ANOVA type test data sex<-c(rep(1,8),rep(0,8))

My subject line refers to a thread from June 2005 where I found explanations from Uwe Ligges and Friedrich Leisch as to what is intended by the R citation recommended within the software. Forgive me if I missed some points within the thread but when I found myself circling through messages I had already read, I stopped trying to follow it. I understand and mostly agree with how the R citation is

I am working with some survival data with missing values. I am using the mice package to do multiple imputation. I have found code in this thread which handles pooling of the MI results: https://stat.ethz.ch/pipermail/r-help/2007-May/132180.html Now I would like to plot a survival curve using the pooled results. Here is a reproducible example: require(survival) require(mice) set.seed(2) dt

When I do t.test on two distributions (see example below), it outputs numerous data about the t.test. What I'd like to do is individually capture some of this data and assign it to other variables. However, I am unable to find anything in the help section. In the example below, the t value is -4.0441 and the p-value is 0.006771 How can I assign these values to two variables, let's

Hello all, I noticed that both Windows and OS X version of R have a GUI (Rconsole). Is there a GUI for Linux? I'm running Debian on which the CLI for R works just fine. Regards, - Robert

I ran logistic regression models last week using glm (...,family=binomial) and got a set of results. Since then I have loaded the Epi package for ROC analysis. Now when I run those same models I get completely different results, with most being: Warning message: fitted probabilities numerically 0 or 1 occurred in: glm.fit(x = X, y = Y, weights = weights, start = start, etastart = etastart,

I and my students have been having an odd problem with this release, which is that packages are disappearing. After installation the package is found with the library command, but later in the same session or in a later session, the library command returns a not found error. Then later it is back. Happening on both Windows and OS X, mostly but not entirely with Bioconductor packages. David

I apologize if this is a FAQ -- I kind of recall seeing something along these lines before, but I couldn't find the message when I searched the archives. Problem: 1. I have hundreds of small files in a subdirectory ("c:\\temp") and I would like to combine the files into a single data frame. 2. Individually, it is easy to read each file

Platform: WIN2000 Version of R: 1.6.2 I'm interested in plotting fitted values in a trellis xyplot. I believe the following should work; however, I only get the points (not the fitted lines). library(lattice) trellis.device(bg="white") xyplot(MULTDV~TIME|SUBNUM,data=TEMP, panel=function(x,y){ panel.xyplot(x,y) lines(x,fitted(lm(y~poly(x,1),na.action=na.omit)))

Hello everyone, I'm trying to estimate the parameters of the returns series attached using the GARCH code below, but I get the following error message: Error in solve.default(Hessian) : system is computationally singular: reciprocal condition number = 0 Error in diag(solve(Hessian)) : error in evaluating the argument 'x' in selecting a method for function 'diag' Can

R is included in Fedora Extras. You can skip downloading Extras and updating the packages on the CD by using: yum index | grep R and installing the half dozen or so individual packages that will be listed. The number of packages may be mildly annoying but if you install this way you will be notified of R updates along with all of your other security and application updates through the Red Hat

Looking to the wonderful statistical advice that this group can offer. In behavioral science applications of stats, we are often introduced to coefficients for orthogonal polynomials that are nice integers. For instance, Kirk's experimental design book presents the following coefficients for p=4: Linear -3 -1 1 3 Quadratic 1 -1 -1 1 Cubic -1 3 -3 1 In R orthogonal

Hello all, I'm trying to create a heatmap using 2 matrices I have: z and v. Both matrices represent different correlations for the same independent variables. The problem I have is that I wish to have the values from matrix z to be represented by color intensity while having the values from matrix v to be represented by circle size. I currently have the following in front of me and an unsure

R-helpers: I have a dataset that has 168 subjects and 12 variables. Some of the variables have missing data and I want to use the multiple imputation capabilities of the "mice" package to address the missing data. Given that mice only supports linear models and generalized linear models (via the lm.mids and glm.mids functions) and that I need to fit Cox models, I followed the previous

Alternate title: How can I persuade my students that R is for them? Alternate title: Can R replace SAS, SPSS or Stata for clinicians? I am teaching introductory statistics to twelve physicians and two veterinarians who have enrolled in a Mentored Clinical Research Training Program. My course is the first in a sequence of three. We (the instructors of this sequence) chose to teach R rather than
