Display a very low p-value
Hello R-Help, I ran some analysis and were hit with some low Z-score. I tried to convert it to a p-value, however, it seems like the ceiling is around 1e-16. > 1-pnorm(8) [1] 6.661338e-16 > 1-pnorm(9) [1] 0 Do you have any suggestion how I can display a very low p-value in the form of scientific number format? Thank you very much. Regards, Bhoom [[alternative HTML version deleted]]

Buglet in qbeta?
Hi, I sometimes play around with extreme parameters for distributions and found that qbeta is not always monotone as the following example shows. I don't know whether this is serious enough to submit a bug report (as this example is near to the limitations of floating point arithmetic).

bug in qr.coef() and (therefore) in qr.solve (PR#8476)
[I thought I'd submitted this bug report some time ago, but it's never showed up on the bug tracking system, so I'm submitting again.] qr.solve() gives incorrect results when dealing with complex matrices or with qr objects that have been computed with LAPACK=TRUE, whenever the b argument has more than one column. This bug flows from qr.coef(), which has a similar problem. I believe

Help with pexp( )
Dear all, Sorry for bringing up an old issue: >pexp(50, 0.5) [1] 1 In some cases, pexp() gives CDF=1. I read some discussion in 2002 saying it has been patched. However it's not working in "R2.4.1Patched". Could anyone help me out? Thanks a lot, Jeann _________________________________________________________________ Fine Dining & Fancy Food. Check Out This
