I'm using boot package for some analysis on linear regression
coeficients. My problem is that I can not compute bca intervals, I get
an error message

> bca.ci(blm8901,index=1)
Error in if (!all(rk > 1 & rk < R)) warning("Extreme Order Statistics
used as Endpoints") : 
        missing value where logical needed

The problem is the empinf.reg function that is returning Na when
performing a glm regression, statement

beta <- coefficients(glm(t ~ X))[-1]
I don't see anything strange in t or X, but I'm missing something for

Can someone give me an hint on this ?
