[R] one (small) sample wilcox.test confidence intervals

2010-08-10 Thread Panos Hadjinicolaou
Dear R people, I notice that the confidence intervals of a very small sample (e.g. n=6) derived from the one-sample wilcox.test are just the maximum and minimum values of the sample. This only occurs when the required confidence level is higher than 0.93. Example: > sample <- c(1.22, 0.89,
