? Hallo, which function can i use to do (baseline) logistic regression + goodness of fit tests? so far i found: # logistic on binary data lrm combined with resid(model,'gof') # logistic on binary data glm with no gof-test # baseline logit on binary data

Dear netters, Sorry for cross-posting this question. I am sure R-Help is not a research methods discussion list, but we have many statisticians in the list and I would like to hear from them. Any function/package in R would be able to deal with the problem from this researcher? ---------- Forwarded message ---------- From: Heidi Bertels Date: Tue, Jun 5, 2012 at 4:31 PM Subject: How to best

Hello, The history function doesn't seems to work when I am working with R. I have a .Rhistory file in my working directory and I have tried savehistory(file = ".Rhistory") or the command given in the history help : .Last <- function() if(interactive()) try(savehistory(".Rhistory")) and I get the same error message Error in

Hello everyone, I had a few questions that I have not been able to figure out despite a lot of reading. 1) Adding a title to a multiplot figure: If I plot multiple plots with >par(mfrow=c(2,6)) how do I add an overall title to the figure, not the individual plots? 2) Saving histories on the fly: Is there a .Rhistory equivalent to >save.image() ? I would like to be able to save the

# # r-bugs@r-project.org # ###################################################### Because I work in different directories, but always want to save my .Rhistory in the same place, I have changed the system function savehistory to this: function (file = "D:/R50/.Rhistory") invisible(.Internal(savehistory(file))) When I use q() to quit R, and it asks me whether I want to

Dear R People: I just updated to R-2.10.1 on an Ubuntu Karmic Koala and am getting the following with saving .Rhistory erin at erin-desktop:~$ R R version 2.10.1 (2009-12-14) Copyright (C) 2009 The R Foundation for Statistical Computing ISBN 3-900051-07-0 R is free software and comes with ABSOLUTELY NO WARRANTY.

Dear R users, I am having a minor but annoying issue with R.app. It doesn't retain the history information from the previous sessions. By "history," I mean a record of commands/functions entered into R rather than the list of objects--that is properly recorded in the .Rdata file as well as in a workspace file I save separately. System details: R version 2.9.0 R.app GUI 1.28 Mac OS

NOTE: WinXP, R2.2.0 All, a while back I posted a question about using relative filereferencing. The responses have allowed me to successfully set up the following directory structure: ...\data\raw ...\data\derived ...\prog ...\lst ...\log In the \prog directory I have put an RGui.exe shortcut and "pointed it" at \prog as the "Start In" location. In the same

A quick summary. The reported problem appears to be with (some) previous histories. If you find that neither up arrow nor ctrl-P work in the Rgui console, please delete .Rhistory and try again. We don't know the exact cause, and nothing I can think of can reproduce this. I have no problem taking histories made with rw1001 and reading them in rw1010 and vice versa. If the .Rhistory is really

Hi all, I've ecountered a problem in the last few days with my .Rhistory file not being able to be updated when I quit an R session because its file attributes under Windows have been set as "Hidden". Recently, I put the following line in my global Rprofile file:- history(max.show=Inf) so that I automatically open the entire history file for a project when I begin a session, but I

I have an environment variable `$R_HISTFILE` pointing to `/home/my.username/.RHistory` and the following code in my `.Rprofile` in my home directory: .Last <- function() { if (!any(commandArgs()=='--no-readline') && interactive()){ require(utils) try(savehistory(Sys.getenv("R_HISTFILE"))) } }

With the current version (rw1070), every time I start R it loads a whole bunch of packages, many of which I do not need in a typical session: > search() [1] ".GlobalEnv" "package:methods" "package:ctest" "package:mva" [5] "package:modreg" "package:nls" "package:ts" "Autoloads" [9]

The .Renviron and .First functions do not seem to work the same way on a Mac OS 10.4 as on a Windows XP machine. From working in Windows I am used to creating a new directory for each data analysis project. In the new directory I place First, an .Renviron file consisting of the following text: R_HISTFILE="history.txt" R_HISTSIZE=1000000 Second, an .RData file containing a .First

Rer's, Get ready for this intellectual fest! Linux i686 2.2.14-1mdklinus R-1.0.1 When I try to q() from my workspace, I get the following responses: ############################### > q() Save workspace image?

Dear R-Helpers, I'm fiddling with my .Rprofile in Windows XP & R 2.7.0 Beta. I prefer to manually save my workspace but automatically save my command history via the .Rprofile. That is working fine once I found that "utils::" was required before the loadhistory & savehistory functions. What I would like to do is add a separator line with a date between the histories of each

When I close R and answer yes to save workspace, R automatically loads it and apparently also the command history at start up. I would like to know where R stores this information. I know that I can save .RData and .Rhistory files, but I would like to know how(where) R stores this information automatically. I have not found any .RData or .Rhistory files associated with start up. I am running

Thanks-- as Duncan Murdoch also noted, R_HISTFILE can be used to solve my problem, as below. BTW it's not easy to find out about R_HISTFILE in the help system or manuals, though, unless you already know it exists-- it only seems to be described under startup options, not things to do with history. However, Duncan's reply did hint at an inconsistency, in that savehistory() defaults to

Can anyone offer suggestion about getting readline to work on Solaris? (v1.5.1) When I use the up arrow or ctrl-p to try to repeat the last command my session just beeps. It appears that the .Rhistory file that should appear in my startup directory is not being created. Thanks!

Hi, does anyone know of a function to calculate odds ratios in multiway tables (stratified) (+ the other usual statistics involved) i mean: say we have a table r*c*d, For every d (depth) we have a r*c table, and in this table the odds ratio's are calculated for every 2*2 subtable in it. logically this function would look like): ORs(multiwaytable) or ORs(data$var1r,data$var2c,data$var3d)
