[R] Wilcoxon Mann-Whitney Rank Sum Test in R

[Bob Green]

An earlier post had posed the question: "Does anybody know what is relation 
between 'T' value calculated by 'wilcox_test' function (coin package) and 
more common 'W' value?"

I found the question interesting and ran the commands in R and SPSS. The W 
reported by R did not seem to correspond to either   Mann-Whitney U, 
Wilcoxon W or the Z which I have more commonly used. Correction for ties 
may have affected my results.

Can anyone else explain what the reported W is and the relation to the 
reported T?
