Two-factor ANOVA Help
Hello,
I am trying to perform a two-factor ANOVA analysis using a blocking design with "Vol" as the response variable. My intent is to have "Rater" treated as the treatment variable and the "Pipe" treated as the blocking variable. I am reading and preparing my dataset using the following three lines of code:
values <- read.table("filename",

reducing data.frame
Hi All,
Is there an easy way to reduce a data.frame to 1 'id' per row while keeping
information from the other rows of that same variable, if applicable? e.g.:
# data
multi[1:15,]
id r n wi wi.tau z k alliance a.rater eml
treatment outcome o.rater german
1 100 0.2800000 44 41 21.72514 0.2876821 210 <NA> <NA> <NA>

Help With Fleiss Kappa
Hi All,
I am using fleiss kappa for inter rater agreement. Are there any know
issues with Fleiss kappa calculation in R? Even when I supply mock data
with total agreement among the raters I do not get a kappa value of 1.
instead I am getting negative values.
I am using the irr package version 0.70
Any help is much appreciated.
Thanks and Regards

Bradley Terry model and glmmPQL
Dear R-ers,
I am having trouble understanding why I am getting an error using glmmPQL (library MASS).
I am getting the following error:
iteration 1
Error in MEEM(object, conLin, control$niterEM) :
Singularity in backsolve at level 0, block 1
The long story:
I have data from an experiment on pairwise comparisons between 3 treatments (a, b, c). So a typical run of an experiment

Extracting variance components from lmer
Hi All.
I need a bit of help extracting the residual error variance from the VarCorr
structure from lmer.
#Here's a 2-way random effects model
lmer.1 <- lmer(rating ~ (1|person)+(1|rater), data = dat)
#Get the structure
vc.fit <- VarCorr(lmer.1)
#results in.....
$person
1 x 1 Matrix of class "dpoMatrix"
(Intercept)
(Intercept) 0.7755392
$rater
1 x 1 Matrix

latent class modle for rater agreement
Hello there,
I would like to test the agreement amongst 6 raters for nominal data on
a scale from 1-4, and conduct a latent class analysis in R. How should
the data be formatted and what code should I use?
Thank you very much

Storing results in a single file after looping over all files
Hi All,
I have a whole lot of *.raw files in my working folder and I am doing the same analysis on each of those and want to save all the results in a single file. I am making some mistake here and can't figure out how to solve it.
Say, the *.raw files are ABCD.raw, EFGH.raw, IJKL.raw ...
The files are of this format
ID PHI?? aa1? aa2? aa3 ....
1??? 1???? 1.3?? 2.0?? 1.0
2??? 0????

smooth: differences between R and S-PLUS
Hi!
I am studying differences between R and S-PLUS smooth() functions. I know
from the help that they worked differently, so I ask:
- exist a package that permit to have the same results?
- alternatively, someone know how can I obtain the same results in R, using
a self made script?
I know that S-PLUS use the 4(3RSR)2H running median smoothing and I try to
implement it with the code below. I

stratified kappa (measure agreement or interrater reliability)?
Hi All:
Could anyone point me to a package that can calculate stratified kappa? My
design is like this, 4 raters, 30 types of diagnosis scores, 20 patients.
Each rater will rate each patient for each type of diagnosis score. The
rater's value is nominal.
I know I can measure the agreement between raters for each type of diagnosis
score, e.g., calculate out 30 kappa values. My problem is I

Star Rating Component?
Hi,
I''m looking for a star rating component for RoR, a bit like Votio
(http://redalt.com/downloads/ - find the votio heading) or the star
rating used on Amazon.
I don''t really need the AJAX capabilities, just the ability to bind the
results to a hidden drop down, or radio inputs.
Multiple raters per page is also an issue.
Any recomendations?

splitting a string column into multiple columns faster
Hello!
I have a column in my data frame that I have to split: I have to distill
the numbers from the text. Below is my example and my solution.
x<-data.frame(x=c("aaa1_bbb1_ccc3","aaa2_bbb3_ccc2","aaa3_bbb2_ccc1"))
x
library(stringr)
out<-as.data.frame(str_split_fixed(x$x,"aaa",2))
out2<-as.data.frame(str_split_fixed(out$V2,"_bbb",2))
