?wilcox.test
?friedman.test

etc. - it's true. I didn't find an easy way to find certain test in R
either. But e.g.

  apropos("wilcox")

will help.

Furthermore I recommend the book

@Book{siegel88,
  Author         = {Siegel, S. and Castellan, N. J.},
  Title          = {Nonparametric Statistics for the Behavioral Sciences},
  Publisher      = {McGraw-Hill, Inc.},
  Address        = {Singapore},
  year           = 1988,
}

Regards,
  Christoph.
