Sorry folks but again I have failed in my understanding of how to do a very simple thing. I've read the various texts and searched the help archives but no positive result so far. I want to remove all the rows in a data frame where one of the variables has negative values. In approx Stata pseudocode: drop _all, if( x < 0 ) Please either point me to relevant sections of the docs or

Is there a colinearty function implemented in R? I have tried help.search("colinearity") and help.search("collinearity") and have searched for "colinearity" and "collinearity" on http://www.rpad.org/Rpad/Rpad-refcard.pdf but with no success. Many thanks in advance, Peter Lauren.

Hi, I am computing the Nelson-Aalen (NA) estimate of baseline cumulative hazard in two different ways using the "survival" package. I am expecting that they should be identical. However, they are not. Their difference is a monotonically increasing with time. This difference is probably not large to make any impact in the application, but is annoyingly non-trivial for me to just

I noticed that there is a newer version of Tom Short's "cheat sheet" than the version currently posted on CRAN. Personally I like the newer version, but maybe keeping the old version is deliberate. Anyway, I was wondering if there's someone that I can notify that can update the content. New version: http://rpad.googlecode.com/svn/Rpad_homepage/R-refcard.pdf CRAN version:

I hope this question is sufficiently different from the other requests for book recommendations that it's not repetitious. If not, I apologize in advance. I'm curious what standard reference books working statisticians, or biostatisticians, have within easy reach of their desk. I'm a computer systems administrator, and have a two-foot bookshelf directory under my monitor that contains

This is a generic request concerning were to look for finding appropriate information on a precise procedure in R. I’m using R for teaching introductory statistics and my students are learning how to deal with it. However, I find it difficult to locate some of the procedures. For instance, for basic crosstabulation, it is obvious that basic functions as table, ftable, and prop.table can be used.

Hi all, I am running R 2.0.1 under Windows XP in German. I configured my path as follows: C:\Programme\R\rw2001\bin;C:\Programme\xemacs-packages\lib-src\;C:\Programme\XEmacs-21.4.13\i586-pc-win32 I can not start R proccess or ESS from within XEmacs. What is going wrong? I can not start S. M-x S gives "no matching" How can I configure XEmacs for STATA 8? Thanks for your help. M

Hi R experts I am just wondering if something is already available (or easily adaptable) to do the following. I am planning to build linear models for all possible combinations of terms, so for example if the terms are sent into a function as this string " X1 + X2 + X3 + X4 + X1:X2" I would want to build models for all possible combinations of these 5 terms, e.g. m1 <- lm( y ~
