Inquiry About R Packages for Specific Research Areas
...olves 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 confirm which
of these (or others) would be most suitable for our needs?
Dietary Intake/Analysis: We are considering packages like foodfreq and
Dietary for dietary intake analysis. Are these the best options, or do you
recommend other packages for this purpose?
Pedigree Analysis: We are exploring the kinship2 and pedigree packages for

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?
I looked for such functions in the documentation, but couldn'...

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

Review: The South Beach Diet was the second diet that I tried after

Plus every candy made by Brach's . External factors such as over
exposure to sunlight, pollution, stress, smoking and poor dietary habits
are factors that we do have control over. Scientists are trying to

into becoming certain types of cell.

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

2.7.0. Everything went OK except this:
sudo R CMD check pgirmess

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