Spearman correlation and ties

Question

I\'m computing Spearman\'s rho on small sets of paired rankings. Spearman is well known for not handling ties properly. For example, taking 2 sets of 8 rankings, even if 6 a

Answer 1

I think exact=FALSE does the trick.

cor.test(c(1,2,3,4,5,6,7,8), c(0,0,0,0,0,0,7,8), method="spearman", exact=FALSE)

    Spearman's rank correlation rho

data:  c(1, 2, 3, 4, 5, 6, 7, 8) and c(0, 0, 0, 0, 0, 0, 7, 8)
S = 19.8439, p-value = 0.0274
alternative hypothesis: true rho is not equal to 0
sample estimates:
      rho 
0.7637626
