Is Spearman's cor.test in R tie corrected or not?
correlation, r
Solution
The "official" documentation is the code itself. And looking there, one sees that there is provision for correction for ties through the use of `pkendall()`.

Problem
I was wondering if the cor.test function in R to compute Spearman's rho is tie-corrected or not. I couldn't find a straight answer in the official R documentation. An example of tie corrected Spearman is found in: Cureton, Edward E. The average spearman rank criterion correlation when ties are present. Psychometrika 23, no. 3 (September 1958): 271-272. Thanks for any hint, Mulone
