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?

"bluefish", the search returned no result.

A casual search of google using terms like "MCMC", "Markov Chains", "Monte

Hi All:
I was looking for, but could not locate in the packages, or in the R archive searches if there exists an R implementation of Cuzick's test of trend. The test is described as follows:
An extension of the Wilcoxon rank-sum test is developed to handle the situation in which a variable is measured for individuals in three or more (ordered) groups and a non-parametric test for trend
