Version: R-1.8.0
OS: Windows (but own compilation)
Submission from: (NULL) (139.133.7.38)
the p-value is incorrect for cor.test using method "spearman" in R-1.8.0. This
was not the case in R-1.7.1.
Version R-1.8.0 on Windows
> cor.test(rnorm(50),rnorm(50),method="spearman")
Spearman's rank correlation rho
data: rnorm(50) and rnorm(50)
S = 20486, p-value = < 2.2e-16
alternative hypothesis: true rho is not equal to 0
sample estimates:
rho
0.01627851
> cor.test(rnorm(50),rnorm(50),method="spearman")
Spearman's rank correlation rho
data: rnorm(50) and rnorm(50)
S = 22006, p-value = 1
alternative hypothesis: true rho is not equal to 0
sample estimates:
rho
-0.05671068
