...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 pedigree data analysis. Is there a package...

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'...

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 the rows of

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
