Hello everybody, does anybody know how the function plot.survfit exactly works? I'd like to plot the log of the cummulative hazard against the log time by using plot.survfit(...fun="cloglog") which does not work correctly. The scales are wrong and there is an error message about infinit numbers. It must have something to do with the censored data, doesn't it? #Example:

Good morning everyone (or maybe good evening) Is there a counterpart to the s-plus function "probplot" (which provides a qq-plot for "survreg"-objects)? Or do exist other (rather simple) possibilities to check the assumptions of the distribution? I have another question to the author(s) of summary.survreg: Why does summary(...,times=sort(x)) not give the same result as

I am using R for a class which uses S. Often I can not find functions that in S but not in R, example, multicomp(). What is your advise.

Dear R people, I have heard rumors of a function called (I believe) multicomp in S+ for doing multiple comparisons for linear models. It doesn't seem to be in the version of R I am using, 0.90.0. Is there something equivalent to this in R, or does it simply not exist? I see there is are more recent versions of R. For my platform, SuSE Linux, the most recent rpm available appears to be

Is there a fonction for multiple comparison tests (similar to "multicomp" in Splus) in a package of R? Thanks in advance for any hint...

Dear list members, First of all thank you for your helpful advices. After your answeres to my firt mail I studied a lot (R-News n?5) and I tried to perform my analysis: First, to fit a GLM with a nested design I decided to use the function "lmer" in package "lme4" as suggested by Spencer Graves and Filippo Piro. I remember to you that my data were: land use classes, 3 levels

Dear R core team I've a proprosal to improve the function interaction.plot. It should be allowed to use type = "b". This can be done by changing the function's header from function( , type = c("l", "p"), ) to function( , type = c("l", "p", "b"), ) Then it works. This type = "b" is useful, if

Dear R Core Team I've a proposal to improve drop1(). The function should change the contrast from the default ("treatment") to "sum". If you fit a model with an interaction (which ist not signifikant) and you display the main effect with drop1( , scope = .~., test = "F") If you remove the interaction, then everything's okay. There is no way to fit a

Hello I'd like to try out some functions in the package randomForest. Therefore, I did install this package. However, it is not possible to load the library, although I have R-Version 2.1.1 (i.e. later than 2.0.0). The commands I used and the Answers/Error from R is as follows: > install.packages("C://Programme//R//rw2011//library//randomForest_4.5-16.zip",

I suppose that multcomp in R and multicomp in S-Plus are related and it appears that it is possible to use multicomp with lme in S-Plus given the following correspondence on s-news sally.rodriguez at philips.com 12:57 p.m. 24/04/03 -0400 7 [S] LME summary and multicomp.default() Is it possible to use multicomp with lme in R and if so what is the syntax from a simple readily available

Hi I have some experimental data where I have counts of the number of insects collected to different trap types rotated through 5 different location (variable -location), 4 different chemical attractants [A, B, C, D] were applied to the traps (variable - semio) and all were trialled at two different CO2 release rates [1, 2] (variable CO2) I also have a selection of continuous variables

I would like to use a tclArray: mytkarray <- tclArray() as the variable for a table: table1 <- tkwidget(f1, 'table', variable= mytkarray) but if I include character strings with embedded spaces, I get braces appearing in the table. I can remove them using a non-R tclarray, (the difference between the first example of http://www.sciviews.org/_rgui/tcltk/Tktable.html and

Dear all, I have been running some tests of my package RSiena on different platforms and trying to reconcile the results. With Mac, the commands options(digits=4) round(1.81652, digits=4) print 1.817 With Windows, the same commands print 1.816 I am not bothered which answer I get, but it would be nice if they were the same.

Dear R People, I?m trying to link R and TK. I?m using R 2.11.1 with Tinn-R 1.17.2.4. For simple examples like the following one it?s working (see the initiation of the variables, the handler and the link to the function which multiply Zahl, Exponent and Factor) : require(tcltk) Ergebnis<-tclVar(c(0,0,0,0,0,0)) Zahl<-tclVar(c(0,0,1,1,1,0)) Exponent<-tclVar(c(1,1,1,1,1,1))

Dear R core team Using the following code produces an empty plot (similar to col = NA): > plot(1:9, col = factor(rep(1:3,3), labels = c("red", "blue", "black"))) My question: Shouldn't one get at least a warning (or an error) if one tries to use a factor as col argument? Thanks for an answer. Regards, Christoph Buser

Dear R gurus I've a question concerning the transformation of a new S4 class (that I defined) and the existing class "POSIXlt". I did the following: ## Definition of the new class: setClass("dtime", representation(data = "POSIXlt"), prototype(data = as.POSIXlt("2004/06/01"))) ## Transformation between the new class "dtime"

Dear R core team Please apologize for posting the same question twice on R-help and R-devel. Since I was not sure which list is appropriate I tried R-help (Tue Mar 22), but got no answer. Now I do not know if the formulation of my question was unclear or the question is not so easy to answer or to easy (what I do not hope). My problem: I create a new S4 class, containing one slot, data (of
