Full_Name: Chanseok Park Version: R 2.2.1 OS: RedHat EL4 Submission from: (NULL) (130.127.112.89) pbinom(any negative value, size, prob) should be zero. But I got the following results. I mean, if a negative value is close to zero, then pbinom() calculate pbinom(0, size, prob). dbinom() also behaves similarly. > pbinom( -2.220446e-22, 3,.1) [1] 0.729 > pbinom( -2.220446e-8, 3,.1)

Full_Name: Chanseok Park Version: 1.8.1 OS: linux-gnu Submission from: (NULL) (130.127.112.183) digamma with any negative value does not give a right answer. It gives -1.797693e+308 for any negative arguments. For example, digamma(-1.1) gives -1.797693e+308. The right answer should be 10.15416 This bug can be easily fixed by using the following digamma identity. digamma(x) = digamma(1-x) -

I was just curious if anyone knew of an alternative model to logistic regression where the probabilities seems pretty linear to the predictor rather than having that S shape that probit and logit assume. Maybe there is there some kind of other GLM that could accomplish that. Any textbook references or suggestions are appreciated. I have most of the texts but if someone knows of a text that talks

I added a virtual interface eth0:1 on one of my machines and suddenly networking breaks on startup of the system (eth0 is gone) when xend starts and runs the network-bridge script. This is supposed to be fixed according to: https://bugzilla.redhat.com/show_bug.cgi I checked and the network-bridge script contains this fix. It works fine on one of my PCs when eth0:1 is added, but not on this

In auth2-hostbased.c, line #146 if (auth_rhosts2(pw, cuser, chost, chost) == 0) ^^^^^ shouldn't this be if (auth_rhosts2(pw, cuser, chost, ipaddr) == 0) ^^^^^^ The code was found in 4.2. Best regards, Choung S.Park

Dear Sir/Madam: I simply want to draw x-y plot with Julian dates (x) and numbers (y). Please see below for my program. In the older version of R, the plot(jdat, miles) worked without any problem. But, with the new version of R, plot(jdat, miles) does not work any more. So, I added log="" option (as far as I know, it is a default setting, so log="" should not be needed).
