Dear all,
I have P value of a list of markers. Now I need the chi square value
with degrees of freedom 2.
I noticed there are several Chisquare functions (dchisq, pchisq,
qchisq, and rchisq), but it seems all are not for my purpose.
In microsoft excel, there is a function CHINV to do this, such as
CHINV(0.184, 2) is 3.386, that means the chi square value for P value
0.184, degree 2 is 3.386.
Does the R package has some function to do this?
qchisq(0.184, df=2, lower=FALSE)
