R> library("exactRankTests")
R> x <- c(1.83, 0.50, 1.62, 2.48, 1.68, 1.88, 1.55, 3.06, 1.30)
R> y <- c(0.878, 0.647, 0.598, 2.05, 1.06, 1.29, 1.06, 3.14, 1.29)
R> wilcox.exact(x, y, paired = TRUE, alternative = "greater")
Exact Wilcoxon signed rank test
data: x and y
V = 40, p-value = 0.01953
alternative hypothesis: true mu is greater than 0
is one of the examples shown in ?wilcox.exact
Best,
Torsten
