[MINC-users] RMINC - Calculating p-value for the Wilcoxon test

[Tom Beaudry]

Hi,

I am using RMINC to calculate the W value for an analysis with group sizes
of 6 and 19. I then get some W values (from 1-114), but how can I calculate
the associated p-value from the W-Value?

This is the R code that I am using:

rm(list=ls(all=TRUE))
library(RMINC)
gf1 <- read.csv("input.csv")
vs1 <- minc.model(gf1$FA, gf1$group, "wilcoxon")
vs1[is.na(vs1)] <- 0
mincWriteVolume(vs1, "output.mnc", gf1$FA)

thanks for the help!
