Turning off warnings from cor.test
check option 'warn' in the on-line help file of ?options(), e.g., you can use something like this: op <- options(warn = (-1)) # suppress warnings cor.test(c(1,2,3,3,4,5), c(1,2,3,3,4,5), method = "spearman") options(op) # reset the default value, if you want I hope it helps. Best, Dimitris

I would like to turn off the warnings from cor.test while retaining exact=NULL. Is that possible ?
cor.test(c(1,2,3,3,4,5), c(1,2,3,3,4,5), method = "spearman")
Spearman's rank correlation rho
data: c(1, 2, 3, 3, 4, 5) and c(1, 2, 3, 3, 4, 5)
S = 0, p-value < 2.2e-16
alternative hypothesis: true rho is not equal to 0
sample estimates:
rho
1
Warning message:
In cor.test.default(c(1, 2, 3, 3, 4, 5), c(1, 2, 3, 3, 4, 5), method =
"spearman") :
Cannot compute exact p-values with ties
