Dear Sir,

I am comparing two samples using wilcox.test in R.  Literature appears to describe mann whitney u test as the most appropriate test to use on my data.

is the wilcox.test function equivalent to mann-whitney u?  Is there a way to gain the U-value as apposed to the W-value in R?

Thank you
