roccomp
Does anyone know of a way to compare to ROC curves in R using the same method
used by roccomp in Stata?

External Backup Systems?
Hey everyone,
My home server just had a disk failure a few weeks ago and like a lot of
people I haven't ever really made backups on a regular basis. So I was
looking into backup solutions which will save me from this situation
again.
Now I have Bacula setup, and backing up my files onto my home server.
Although this works great, I have one issue: The disk in my server was

Bug in legend?
This is a bit obscure but caused me some grief... R1.5.1/MS
Windows
There seems to be a peculiarity in legend associated with the use
of expression text. It seems as if expression text is used in (eg) an
mtext call then if the call to legend also includes expression text
and a subscript then the legend box and line spacing depends on
the value of cex used in the previous call to mtext,

Probit cluster-robust standard errors
If I wanted to fit a logit model and account for clustering of observations, I would do something like:
library(Design)
f <- lrm(Y1 ~ X1 + X2, x=TRUE, y=TRUE, data=d)
g <- robcov(f, d$st.year)
What would I do if I wanted to do the same thing with a probit model?
?robcov says the input model must come from the Design package, but the Design package appears not to do probit?
Thanks very

Drawing lines in margins
Hi all,
Quick question: What function can I use to draw a line in the margin of a plot? segments() and lines() both stop at the margin.
In case the answer depends on exactly what I'm trying to do, see below. I'm using R v. 2.8.1 on Windows XP.
Cheers,

MuMIn Problem getting adjusted Confidence intervals

why results from regression tree (rpart) are totally inconsistent with ordinary regression
Hi,
In my analysis of impacts of insecticide-treated bednets on malaria, I
look at the relationship between malaria incidence and mosquito
behaviors. The condensed data set is copied here. Ordinary regression
(lm) shows that Incidence was negatively related to Mortality. This
makes sense because the latter reflected the strength of killing
mosquitoes by insecticide-treated nets. Since the

Cairo package failure to load backend
Hi R friends,
I've been attempting to create plots with multiple alpha values using
Cairo to save them on a windows (32b XP) platform as it doesn't support
more than 3 alpha values. This worked well until I wanted a postscript
file (unsupported) and as a attempted work around I installed RGtk2. So
far so good, however now when I try to use a

glmm for binomial data? (OT)
A while ago (April 2002) there was a short thread on software for generalized
linear mixed models.
Since that time, has anyone written or found R code to use a glmm to analyze
binomial data? I study CWD in white-tailed deer, and I'd like to do a
similar analysis as Kleinschmidt et al. (2001, Am. J. Epidemiology 153:
1213-1221) used to assess control for spatial structure in malaria

R CMD build now removes empty dirs
Hi,
It's unfortunate that with recent revisions of R 2.13 (this
appeared in revision 54640, March 2), 'R CMD build' now removes
empty dirs in the package. People might have good reasons for
having empty dirs in their packages. For example, in Bioconductor,
we have some tools to automatically generate annotation packages
and those tools are implemented in software packages that use

Function to recognise convert dates between gregorian and other calendars (e.g. Persian)?
Dear list,
I will shortly have some data that contains numeric dates in the Persian /
Jalali calendar format, which I would like to convert to gregorian. At the
moment there doesn't seem to be a function for this in R, but it would be
great if someone could come up with same - I would attempt it but the
algorithm is very complex and this is also way beyond my fairly rudimentary
knowledge of

random effects using lmer
Hi,
I am trying to run a logistic regression to look at the risk of malaria
infection in individuals. I want to account for intra household correlation
and so want to include a household level random effect. I have been using
the lmer command in lme4 package but am getting some strange results that
are completely different to those I get using STATA.
Can I just check that this is the correct

lattice package: line end style
First, apologies for no example data but I don't think it's needed in
this case,
Q: Can (and if so how ) the line end style be changed for 'cloud' plots?
I've tried par(lend=2), trellis.par.set(add.line = list(lend=2)) and
much googling but to no avail
Thanks in advance
Dan
P.S. the reason for this is that the round end looks bad at lwd=3 or

How to compare areas under ROC curves calculated with ROCR package
Dear all,
I try to compare the performances of several parameters to diagnose
lameness in dogs.
I have several ROC curves from the same dataset.
I plotted the ROC curves and calculated AUC with the ROCR package.
I would like to compare the AUC.
I used the following program I found on R-help archives :

Survey of ROC AUC / wilcoxon test functions
Hi,
I was lately debugging parts of my 'colAUC' function in caTools package, and
in a process looked into other packages for calculating Areas Under ROC
Curves (AUC). To my surprise I found at least 6 other functions:
* wilcox.test
* AUC from ROC package,
* performance from ROCR package,
* auROC from limma package,
* ROC from Epi package,
* roc.area from verification
