Hi,
I am using R to perform wilcox.test and wondering if you know how the p-value in wilcox.test is calculated?
You can get the source code of the wilcox.test function:
> methods(wilcox.test) [1] wilcox.test.default* wilcox.test.formula*
Non-visible functions are asterisked > getAnywhere(wilcox.test.default)
...
You will see that it uses 'psignrank' (for the one sample case).
