Is this what you are after: this comes from the example of wilcox.test and shows the structure and how to reference the p-value:
> z <- wilcox.test(x, y, paired = TRUE, alternative = "greater") > str(z) List of 7 $ statistic : Named num 40 ..- attr(*, "names")= chr "V" $ parameter : NULL $ p.value : num 0.0195 $ null.value : Named num 0 ..- attr(*, "names")= chr "location shift" $ alternative: chr "greater" $ method : chr "Wilcoxon signed rank test" $ data.name : chr "x and y" - attr(*, "class")= chr "htest" > z$p.value [1] 0.01953125 On Tue, Jul 29, 2008 at 1:00 AM, Paul Adams <[EMAIL PROTECTED]> wrote: > I have run a wilcox test on a dataframe and I have returned to me data which > I am wanting to sort and/or pick the max. > I have tried the following code to pick the max: > v<-wilcox.test.run > w<-max(v,na.rm=FALSE) > > I have also tried w<-pmax(p-value,na.rm=FALSE) for the second line > > and this returns the following error:invalid 'type' (list) of argument > This error is understandable because I am trying to find the max p-value from > a list of > 100 with the following output: > > > $g100 > Wilcoxon signed rank test > data:newX[,i] > V=741, p-value=8.051e-08 > > I want to be able to pull only the maximum p-value from this output and the > $g that matches the p-value by using max.Any help would be appreciated. > > Thanks > Paul > > > > > > [[alternative HTML version deleted]] > > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > > -- Jim Holtman Cincinnati, OH +1 513 646 9390 What is the problem you are trying to solve? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
