Full_Name: Manikandan Narayanan Version: 2.8.1 OS: Linux Submission from: (NULL) (155.91.45.231) Here is an excerpt from qpois help page (?qpois): The quantile is left continuous: 'qgeom(q, prob)' is the largest integer x such that P(X <= x) < q. I think the "qgeom" here should be "qpois" instead. Please correct this typo in ?qpois, since it's misleading in its current form. Thanks!

...he trail that an event occurs, with a constant probability p (or prob). Contrary to R, my textbooks have x = 1, 2, 3, ... My intuition says that with this interpretation, a probability of 0 means that the event just won''t happen, and consequently rgeom(1,prob=0) should always return Inf. qgeom() seems to agree: > qgeom(1,1) [1] Inf rgeom(1,prob=1) says to me that the event must occur on the first trail, and with x = 0, 1, 2, ..., that means it should return 0. Here, > qgeom(0,0) [1] NaN Warning message: NaNs produced in: qgeom(p, prob, lower.tail, log.p) Is it my intuition tha...

There is a problem with `rpois'. It does seem to take care about the order of the arguments. This is an example: > rpois(n=1,lambda=2) [1] 3 > rpois(lambda=2,n=1) [1] 2 0 It obviously uses the first argument as the number of samples to be drawn, which is wrong. I used Version 0.49 Beta (April 23, 1997). Fredrik

Hi, With R version 2.10.0 (2009-10-26) on Windows, I computed the p=1.e-20 quantile of the geometric distribution with parameter prob=0.1. > qgeom(1.e-20,0.1) [1] -1 But this is not possible, since X=0,1,2,... I guess that this might be a bug in the quantile function, which should use the log1p function, instead of the naive formula. Am I correct ? Best regards, Micha?l

1. lbeta and beta do not work properly: lbeta returns its first argument and beta gives the lbeta result. In names.c lines 245-6, the codes for these should be 2 and 3 instead of 1 and 2 2. crtl-C does not work (except the first time) on Red Hat elf Linux (which has many many other problems as well) nor on the previous version of Linux for Amiga. It worked on Slackware aout Linux and now works
