Pardon my ignorance, but is there a difference in cor.test between exact=FALSE and exact=NULL when method=spearman?
Take for example: x<-c(1,2,2,3,4,5) y<-c(1,2,2,10,11,12) cor.test(x,y, method="spearman", exact=NULL) This gives an error message, Warning message: Cannot compute exact p-values with ties in: cor.test.default(x, y, method = "spearman", exact = NULL) However, when exact is changed to FALSE, this seems to run okay. cor.test(x,y, method="spearman", exact=FALSE) Question: should this be exact = FALSE in the documentation and/or the code?
