Subject: wilcox.test statistics

Hi,

Could anyone provide the formula of the statistics which the wilcox.test 
used for the two-sample rank-sum test?  I got some statistics of 0 values, 
but it is impossible to have 0 "rank-sum".  Does the function use the 
Mann-Whitney U test statistics?  Thanks.
