Plotting the P value

Ali,

I'm not completely sure of your purpose but I have my students use plot.htest() in my NCStats package (available at rforge.net/NCStats) to plot the p-value following the results of z.test() (from TeachingDemos package), t.test(), or chisq.test().  You might also consider distrib() in NCStats (it is more general and is simply a wrapper to pnorm(), qnorm(), etc. and won't, for example, show a two-tailed alternative).  Examples of both are in the help pages -- ?plot.htest or ?distrib.

Dear? All R users:



Can someone help me with the plotting the p-values under the normal curve
(say).



Thank you so much.
