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.

David.
