| Apr 5, 2013 at 18:17 | comment | added | Primigenius | Another way to obtain z from standard wilcox.test is the algorithm Andy Fields implemented in his function rFromWilcox. And yes, I was referring to effect size = z / sqrt(N). | |
| Apr 5, 2013 at 9:43 | comment | added | Primigenius | The reason ti use coin::wilcoxsign_test is that it computes a z value. | |

I suspect this reply would be of higher interest if you could supply additional details on the reasons to use the coin::wilcoxsign_test R function. Also, are you referring to the OP formula, $\text{effect size} = z / \sqrt{N}$?
