[R] exact values for p-values

Hi there, If I do an lm, I get p-vlues as p-value: 2.2e-16 Suppose am interested in exact value such as p-value = 1.6e-16 (note = and not ) How do I go about it? stephen __ R-help@stat.math.ethz.ch mailing list

Re: [R] exact values for p-values - more information.

If they have the same degrees of freedom, use the test statistic and not the p value for comparing them. Z I appretiate your input to this discussion. Do you know of a reference to your statement above? I had actually used the test-statistic which in my case is r-squared to compare them.

Re: [R] exact values for p-values

there is no such thing as an R lib. Do you mean R package? Yes. I usually refer to them R packages as as libraries, hence the use of lib. Regards. Stephen. In any case, not it is not (yet). As David clearly says (a few lines below), it is a 'f90' library; which means it's fortran 90
