Inquiry About R Packages for Specific Research Areas
Dear R Support Team,
I hope this email finds you well.
I am writing to inquire about the specific R packages that would best suit
our academic research project, which involves analyses in various fields.
We are particularly interested in the following areas:
Epidemiology Analysis: We are aware that packages like epiR, survival, and
epitools exist for epidemiological analysis. Could you please

multiple plots using summary in rms package
Dear All,
I wonder if someone can point me in the right direction here. I'm working
with the rms library, R 2.9.2 under Windows XP.
I'm trying to arrange two plots side by side for a colleague. mfrow or
mfcol do not seem to work, however, so I am obviously missing something
important. I know that there have been changes in the graphics from Design
to rms, but am just not sure where to

Looking for help in calculating percentiles
Hi All:
I am working with a dataset on Arsenic toxicity, and I am trying to
calculate the 20th, 40th, 60th, 80th, and highest percentiles for a
variable, dietary Moisture (variable name dMoist).
The inbuilt function quantile(dMoist) would print 0, 25th, 50th, 75th, and
100th percentile. Does there exist a function that can calculate xth
percentile (where x = 10th, 20th, ... etc) values?

Fisher Test in R
Suppose we have the following data set:
Men Women
Dieting 10 30
Non-dieting 5 60
If I run the Fisher exact test in R then what does alternative = greater (or
less) imply? For example:
mat = matrix(c(10,5,30,60), 2,2)
fisher.test(mat,alternative ="greater")
I get the p-value = 0.01588 and odds ratio = 3.943534. Also, when I flip

Can lmer() fit a multilevel model embedded in a regression?
I would like to fit a hierarchical regression model from Witte et al.
(1994; see reference below). It's a logistic regression of a health
outcome on quntities of food intake; the linear predictor has the form,
X*beta + W*gamma,
where X is a matrix of consumption of 82 foods (i.e., the rows of X
represent people in the study, the columns represent different foods,
and X_ij is the amount of

SIAR problem with model running
Hi there,
I am trying to run an MCMC on stable isotope data from certain organisms to

(also better known as 'SIAR for dummies'), which is as follows:

svyglm
Dear Professor Lumley
I am relatively new to using R and also to logistic regression. We have
analysed our Dudley Health Survey using the survey package. I am now
trying to look at associations using svyglm but I am unsure of how to
interpret the output and present the resulting model or whether there
are any other things I should do to check the validity of the model.
Below is an example of

help: advice on the structuring of ReML models for analysing growth curves
Hi R experts,
I am interested on the effects of two dietry compunds on the growth of
chicks. Rather than extracting linear growth functions for each chick and
using these in an analysis I thought using ReML might provide a neater and
better way of doing this. (I have read the pdf vignette("MlmSoftRev") and
"Fitting linear mixed models in R" by Douglas Bates but I am not

troubles with R CMD check and examples under Ubuntu gutsy
Dear listers,
I was used to package pgirmess under Windows with everything OK, but,
for the first time, I had a trial this afternoon on Ubuntu 7.10 gutsy (I
have a double boot computer and work more and more under unix) and R
2.7.0. Everything went OK except this:
sudo R CMD check pgirmess

* checking examples ... ERROR
Running examples in 'pgirmess-Ex.R' failed.
