chi square table

Hi,

How do we get the value of a chi square as we usually look up on the
table on our text book?

i.e. Chi-square(0.01, df=8), the text book table gives 20.090

dchisq(0.01, df=8)

[1] 1.036471e-08

pchisq(0.01, df=8)

[1] 2.593772e-11

qchisq(0.01, df=8)

[1] 1.646497

nono of them give me 20.090

Thanks,
cruz

qchisq(0.99, df=8)

[1] 20.09024
