wilcox.test exits with error message when confidence interval required, under some situations. I suspect this occurs when the data contain a zero and for some data lengths only: print(wilcox.test(c(2,1,4,3,6,-5,0),conf.int=T)) fails print(wilcox.test(c(2,1,4,3,6,-5,0,1),conf.int=T)) works print(wilcox.test(c(2,1,4,3,6,-5,1),conf.int=T)) works Apologies if this is known - did search bug lists first.
