Hi there, I've looked through the very helpful advice about adding fitted lines to plots in the r-help archive, and can't find a post where someone has offered a solution for my specific problem. I need to plot logistic regression fits from three differently-sized data subsets on a plot of the entire dataset. A description and code are below: I have an unbalanced dataset

Dear R users, i'm using a custom function to fit ancova models to a dataset. The data are divided into 12 groups, with one dependent variable and one covariate. When plotting the data, i'd like to add separate regression lines for each group (so, 12 lines, each with their respective individual slopes). My 'model1' uses the group*covariate interaction term, and so the coefficients

Hello R-helpers, I have 10 dataframes (named data1, data2, ... data10) and I would like to add 5 new columns to each dataframe using the following code: data1$LogDepth<-log10(data1[,2]/data1[,4]) data1$LogArea<-log10(data1[,3]/data1[,5]) data1$p<-2*data1[,6]/data1[,7] data1$Exp<-data1[,2]^(2/data1[,8]) data1$s<-data1[,3]/data1[,9] ...but I would prefer not to repeat this chunk of

Hi R-users, I'm attempting to fit a number of mixed models, all with the same structure, across a spatial grid with data points collected at various time points within each grid cell. I'm trying to use a 'for' loop to try the model fit on each grid cell. In some cells lme does not converge, giving me the error: Error message: In lme.formula(logarea ~ year + summ_d, data =

Folks; I am having a hell of a time trying to get IceCast 2.0 installed on an Apple XServe running OS X 10.2.3. The problem seems to stem from one of the libraries required by IceCast, specifically libvorbis. When running MAKE in an attempt to install libvorbis I get the following: <p>Making all in examples /bin/sh ../libtool --mode=link gcc -DDARWIN -fno-common

Hi, we had a broken heating system (in the floor above us) resulting in a water burst .... my office looks like if a bomb has exploded ... Currently our server is up and running again (it was down over the weekend) ... but we will move out of the devastated rooms and hence the CARN master might be down one or more times during the rest of the week. We'll try to keep the down times as short

Hi all, For several reasons I have no used CARN R in months....I have an idea and I want to retry to learn CRAN R. I know I need to formulate more "intelligent" questions but I will expose and if someone can help me I would be very gratefull I promise to try to learn again.... The question I have a data file like this: Date, Time, Tip 13/11/2008,23:16:00,432 13/01/2009,23:17:00,633

Is there any R package that can help me with digging out the maxima of a 1-D trajectory ? I have 975 1-D curves. They are only known as time series. That is a set of points ordered with respect to time. Some curves exhibit one only peak. Others have two peaks of different height. We wish to find the number of peaks and their position along the time axis. Apparently it's a trivial problem

The following packages have been contributed to CRAN by Thomas Lumley: integrate-1.0.tar.gz: S function and supporting C and Fortran code for adaptive quadrature. The underlyling fortran code is purported to work in from 2 to 20 dimensions. S original by Michael Meyer (mikem at andrew.cmu.edu). R port by Thomas Lumley <thomas at biostat.washington.edu>.

I feel that as long as people continue to provide help on r-help wikis will not be successful. I think we need to move to a central wiki or discussion board and to move away from e-mail. People are extremely helpful but e-mail seems to be to always be memory-less and messages get too long without factorization of old text. R-help is now too active and too many new users are asking

Sorry for this intrusion, but I am confused by two statements that appear to conflict at some level in Writing R Extensions, and wanted to make sure I understand the answer to: Can we distribute a portable executable compiled from source by CRAN in CRAN? The following section of Writing R Extensions appears to not be addressing this issue, as in this case we are discussing portable CRAN compiled

Hi posted this on the forum but then found the mailing list :-) so hope it's ok to post to the list aswell. we have a centos 4.3 server running samba, winbind and squid authenticating by winbind to our NT domain. Once in a while in the early hours it has the below error in /var/log/messages this causes the machine to fail and we carn't connect to it. It's double dutch to me,
