similar to: minor quirk in rnbinom (PR#1669)

I don't want to spoil a nice joke, and recognise it's not a bug as it does have the intended effect, but the error message that is returned if rnbinom is given four parameters is slightly obscure: > rnbinom(0.5,0.5,0.5,0.5) Error in rnbinom(0.5, 0.5, 0.5, 0.5) : couldn't find function "error" > Cheers, Mike.

I am trying to reset the default arguments in the rnbinom function with the following example code: params <- c("size" = 1, "mu" = 1) formals(rnbinom)[names(params)] <- params rnbinom(n = 10) It returns the following: Error in rnbinom(n = 10) : argument "prob" is missing, with no default If I set the defaults with this code: params <- c("size"

The documentation states : An alternative parametrization (often used in ecology) is by the mean ?mu?, and ?size?, the dispersion parameter. However, this fails : > rnbinom(10, mu = 100, size = 0) [1] NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN Warning message: In rnbinom(10, mu = 100, size = 0) : NAs produced For dispersion set to 0, it should work like drawing from a Poisson distribution.

I was having some problems persuading optim() to give me the answers I wanted, & simplified down to: sqr<-function(x){(x+1)^2} optim(1,sqr) I accept this is a hammer to crack a nut, but was still expecting the answer -1. I got: $par [1] -0.8 $value [1] 0.04 $counts function gradient 12 NA $convergence [1] 0 $message NULL so I've

Todays R-1.7.0-beta (see below) compiles fine on, but it doesn't pass make check-all on WinNT4.0, SP6.

Hi there, Finally I got this "Rcomd SHLIB" to like me! The reason was because I did not log in my computer as "administrator", which caused some problem of perl being found... Anyway, thank you all for the prompt and intelligent suggestions. Best, Yunda ---------- Forwarded message ---------- Date: Thu, 13 Jun 2002 18:30:45 -0700 (PDT) From: Yunda Huang <yunda at

Uwe & Marc, Adding the --vanilla flag doesn't help. Actually, the crash happens if I browse to a folder on a mapped drive. I.e., if I type in "q:\Andy" in the text box, it works, but if I try to browse to Q:\Andy and then click on OK, that's when it crashes.

There seems to be a bug in "dotplot" concerning the "cex" parameter. Setting cex has no effect on the character size of the labels of the points. This problem was posted to r-help today (Thu, 18 Jan 2001); the solution given by Brian Ripley (and Uwe Ligges) seems to work for me. Heinrich Rinner. > version _ platform i386-pc-mingw32 arch x86

Hi Jean-Marc, As I told you, bank is a reserved keyword in Analog Devices compiler for Blackfin architecture. So we need to change the variables named bank to something else. Here's a patch that changes bank to bnk in the 3 concerned files. (Hope the format is OK) About my previous problems with the Blackfin: -> strange block repetition that could be cancelled by the AEC I was busy

Hi, I make some simulations with rnbinom and try to test with glm.nb. But in some data set the glm.nb fail. Look: pop <- rnbinom(n=1000,size=1,mu=0.05) > glm.nb(pop~1,maxit=1000) Error in while ((it <- it + 1) < limit && abs(del) > eps) { : missing value where TRUE/FALSE needed look some pop charactetistics: > summary(pop) Min. 1st Qu.

Hi there. Feel like I'm getting nowhere. Code: FreeBSD samba 3.6.6 ; connected to a Windows 2008 R2 AD wbinfo -u and wbinfo -g will properly show all the users and groups ; but for some reasons, I can get getent with winbind to show any users... I've must have tried over 100 different configuration, read all the tutorials I could find ; I never got it to work :( smb.conf: [global]

Dear R-helpers, let us assume, that I have the following dataset: a <- rnbinom(200, 1, 0.5) b <- (1:200) c <- (30:229) d <- rep(c("q", "r", "s", "t"), rep(50,4)) data_frame <- data.frame(a,b,c,d) In a first step I run a glm.nb (full code is given at the end of this mail) and want to predict my response variable a. In a second step, I would

Can any one help? Thanks. we have two * servers (Version 1.2.1) and one 1.09 server. Calls between these two 1.2.1 servers have odd behavior. But call from 1.09 to 1.21 server working fine in either situations.

(Sent this to r-help back in October, got no comments, forgot to re-submit it as a bug report.) There are a few inconsistencies, at least, in some of the functions that generate random deviates from particular distributions (I think they're bugs because they're inconvenient, but maybe someone can make an argument for the current behavior). If people think these are really bugs I can

I've been having troubles getting cross subnet browsing working in existance with a WinNT domain master (hey, it's not my machine). Basically what is happening is that I am trying to setup a VPN (which shouldn't complicate things) that browsing will work across. The idea is this: There is an office in my local city that I'm connecting San Francisco to via VPN. The TCP/IP part is
