I have read the R manual and help archives, sorry but I'm still stuck.
How would I do a t-test with an adjusted p-value?
Suppose that I use t.test ( ) , with the function argument alternative =
"two.sided", and data such that degrees of freedom = 20. The function
calculates a t-statistic of 2.086, and p-value =0.05
How do I then adjust the p-value? My thought is to do
p.adjust (pt(2.086, df=20),"BH")
but that doesn't change anything (returns 0.975)
what is the procedure? I'm sorry if there is a basic concept that I am
missing here...
