In the windows version (RGui), is there a way to set the text displayed in the titlebar of the R window? When I have 2 instances of RGui running, it would be helpul if the titlebar could help to understand which is which. -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-38624 Fax: +43-1-4277-9386

Hi everyone, I am doing 5 years mortality predictive index score with survival analysis using a Cox proportional hazard model where I have a continous predictive variable and a right censored response which is the mortality, and the individuals were followed a maximum of 7 years. I'd like to asses the discrimination ability of survival analysis Cox model by computing a ROC curve and area

Hola Klaus y Jorge , gracias por responder. Intente eso mismo y me borra la columna "y", yo quiero eliminar la columna que se genera en los data frame que contiene el número de registro. En el ejemplo de abajo esa columna va de 1 a 4, cuando exporta el data frame se genera esa misma columna (que no tiene cabecera) Años Edad Dpto 1 Bueno 16,75 1 2 Bueno 16 1 3 Malo

Gracias Jorge, sigue apareciendo la primer columna en el archivo.

In my .Rprofile I have the following functions which display the current directory in the main R window title bar, and modify base::setwd() to keep this up to date. I like this because I can always tell where I am in the file system. cd <- function(dir) { base::setwd(dir) utils::setWindowTitle( short.path(base::getwd()) ) } short.path <- function(dir, len=2) { np

Dear R experts, Attached you can find the expression of a loglikelihood function which I would like to maximize in R. So far, I have done maximization with the combined use of the mathematical programming language AMPL (www.ampl.com) and the solver SNOPT (http://www.sbsi-sol-optimize.com/manuals/SNOPT%20Manual.pdf). With these tools, maximization is carried out in a few seconds. I wonder if that

Hi everybody, Working with interval censored data using S+, I often use the survival analysis' functions kaplanMeier() and censorReg(). Does anybody know, whether these functions exist in R, too?

[Env: Win XP, R 2.14.2, R 2.15.0] I have a replacement function for setwd() in my .Rprofile which displays the current R path in the R window title. It no longer works in R 2.15.x, giving the error below. Worse, the error prevents the rest of my .Rprofile script from completing. Is there some way to rescue this, i.e., preserve this behavior in R 2.15? If not, how can I modify my script so it

In my .Rprofile for Windows, I had the following functions defined to mirror a few features I miss from linux: (a) replace setwd() with a version that stashes the current directory so it can be easily restored (b) writes a short version of the current R directory to the Windows title bar: I can always see where I am, with multiple Rgui windows. (c) creates a cd() shorthand for setwd(), but

I've calculated as follows: matusita<-function(f1,f2,lw,up){ fmatu<-function(x) ( sqrt(f1(x)) - sqrt(f2(x)) )^2 sqrt (integrate( fmatu, lower=lw, upper=up, subdivisions=1000000)$value) } Josué Almansa Unitat de Recerca en Serveis Sanitaris Institut Municipal d'Investigació Mèdica, IMIM c/ Doctor Aiguader, 80 08003 Barcelona e-mail: jalmansa@imim.es

Hi everyone, Does anybody knows if there is an equivalent R function that gives the same outcome as in "Explore" function in SPSS ? (Analize->Descriptive Statistics->Explore) It does a categorical vs quantitative variables analysis. ( But not linear regression) I need to compare intragroup (categorical variable with 4 values) means and confidence intervals of a quantitative

Hola a todos. En linux uso rkward o gedit con el plugin Rgedit, pero me gustaría saber qué editores se pueden usar en windows. He probado Tinn-R , ¿qué usáis vosotros? Gracias

This may be Windows specific, so not appropriate for this List... Currently, when I'm in console of Rgui, the status bar says a simple message "R majer ver. minor ver. - A Language and Environment" which I know. When I'm in plot area, it says "R Graphics" which I know, again. I think it is very useful if statusbars says current directory, because in my daily use I

Hi, Does anybody know how to perform a Cox model analysis for right truncated data? All my data is right truncated, since I only have patients who entered in a hospital for a particular desease, and I would like to modelate the age at hospital entrance as the response variable.

Hi, Anybody knows a function that can fit haplotype data to a Cox model. I've been searching it in the web without succeed. I use "haplo.stats" package, but unfortunatelly it's not possible to analyse survival data, amb I right?. Thanks in advance. Isaac Subirana (isubirana@imim.es) [[alternative HTML version deleted]]

Hi, Does anybody know how to obtain the same information as the SPSS command "DISPLAY DICTIONARY". I know the read.spss function in the package foreign, but it doesn't give either the missing values defined by the user under SPSS or the format variables (for example if they are dates or not).
