R and Epi Info
Hello,
I was wondering who to contact to see about somehow interconnecting or integrating the programs R and Epi Info. I have been involved in the development of Epi Info which is a software program developed by the Centers for Disease Control and Prevention (CDC) in Atlanta (www.cdc.gov/epiinfo<http://www.cdc.gov/epiinfo>). Epi Info allows for creating data entry systems and performs

Name conflict between Epi and ROC packages
The name conflicts in Epi and ROC packages (2 'ROC' functions are the
problem) cause the following code
to work once, but not twice:
library(MASS); data(cats);
x = cats[,2]
y = ifelse(cats[,1]=='F',0,1)
library(Epi); ROC(x,y,grid=0)$AUC
library(ROC); AUC(rocdemo.sca(y, x, dxrule.sca))
What is the standard way of resolving name conflicts? Ask maintainers to
resolve

optimal cut off with Epi package
Dear all,
I would like to calculate the optimal cut off (threshold) of a test using
the Epi package. Here I am presenting some data based on the output of two
tests. I am interested in identifying the optimal cut off an its 95% CI.
Running the ROC() function with the Epi package I obtain a nice picture that
returns what I interpret as the optimal cut off with lr.eta=0.431. would be

epi.2by2
This is a really simple question, I'm sure,but I can't make EpiR work!
I keep getting the following:
> epi.2by2(47, 263483, 282, 935028, method="cohort.time", conf.level=0.95)
Error in epi.2by2(47, 263483, 282, 935028, method = "cohort.time",
conf.level = 0.95) :
unused argument(s) (935028)
and I really don't know why!. Any ideas very very welcome

Epi Info
Hello:
Does anybody knows if Epi Info, from CDC (www.cdc.gov/epiinfo) runs on Wine?
I did try AppDB first but there are no entries for Epi Info.
Epi Info is a data base for epidemiology and public-heath developed by
Centers for Disease Control and Prevention (USA) and heavilly used in
the world. It is based on Access 97 or 2000 witch I found in Frank's
Corner AppDB.
Thank you,

problem with multiple figure postscript file
Hello all!
I'm a newcomer to R, so please bear with me. My problem is the
following:
I'm trying to use R to do some geostatistics stuff (mostly kriging), and
am having trouble printing a multiple figure. When I create a single
figure (one image/contour command), it works fine. The instant I try to
create a multiple figure file, I start getting postscript errors. I'm

how ot get covariance matrix from survreg
I have a question, I generated some data and tried survreg to analyze
them, but here, I want to get the covariance matrix of the coefficients.
I know how to get corr from survreg, say, summary(f,corr=T), but how to
get covariance matrix of the coefficient ?
can I put them in a matrix and output ?
thanks

There is now an Epi-package on CRAN.
It is intended for epidemiological analysis in R.
It has its own homepage, http://www.pubhealth.ku.dk/~bxc/Epi

Adding Functionality to stat.table in Epi
The stat.table function in the Epi package won't do standard deviations.
It didn't seem that it would be difficult to add an "sd" function to the
stat.table function. Following the example for the mean, I set up a
similar function for the sd (and included it as an options) but it just
won't work. (I tried sending messages to the Epi mailing list after
subscribing but my mail

setting pairwise comparisons of columns
Hi,
I have a number of genes (columns) for which I want to examine pairwise
associations of genotypes (each row is an individual)...For example (see
data below), I would like to compare M1 to M2, M2 to M3, and M1 to M3 (i.e.
does ac from M1 tend to be found with bc from M2 more often than expected.)
Down stream I will be performing chi square tests for each pair.
But I am looking for a way to

New version of Epi package out (1.0.7)
A new major upgrade of the Epi package for Epidemiological data analysis
has been put on CRAN, it is now at version 1.0.7.
It contains an entirely new way of representing follow-up data on
multiple timescales and multiple states. See the function Lexis().
Plus a lot of other useful stuff for epidemiological analysis.
See more on the package homepage, www.biostat.ku.dk/~bxc/Epi

CKD-Epi formula
Hi all,
I have a question and I do not know If I am at the right place to ask this question. But is there someone that has the formula of CKD-Epi in code in R?
I have tried a lot of loops, but none of the approaches give me the right answer. Is there someone who has this formula coded?
Thank you!

test Breslow-Day for svytable??
Hi all,
I want to know how to perform the test Breslow-Day test for homogeneity of
odds ratios (OR) stratified for svytable. This test is obtained with the following code:

units = 100, homogeneity = "breslow.day", verbose = TRUE)

problem with normalizePath()

AUC calculated from Epi package
