The wilcoxon test in coin are meant only for "Testing the equality of the distributions of a numeric response in *two or more* independent groups against shift alternatives" whereas the wilcoxon test in the base pacakge "Performs *one-* and two-sample Wilcoxon tests on vectors of data; the latter is also known as âMann-Whitneyâ test."   So, wilcoxon_test and wilcoxonsign_test in coin will not work for one-sample. Why not just use wilcox.test?  Mark J.

However, I couldn't find information on how to run a one sample test using 'wilcoxsign_test' like in the example above. Can anybody help?
