Hi R specialists,
When testing the association between two time series the cor.test gives
the following message...-> p-values may be incorrect due to tie
What does it mean? (it is not described in the help)
Thankx,
Jan
> cor.test(Origi[,1],Origi[,2], alternative = c("two.sided"),method =
c("spearman"), conf.level = 0.95)

data: Origi[, 1] and Origi[, 2]
S = 101457, p-value = < 2.2e-16
alternative hypothesis: true rho is not equal to 0

Origi[, 2], alternative = c("two.sided"),
