[R] wireframe and margins

Hi everybody, I'm working with wireframe (and persp) functions, and I'm not able to set the margins between the 3d plot and the R window... It should be easy, innit?, but I can't find out which parameters I have to change... Any help? Thanks, ktk -- View this message in context: http://r.789695

[R] dbetagen function in mc2d package

Hi all, I found this useful package for generalized beta, yet the function that calculates its density leaves me puzzled, especially when I plotted it: plot(function(y) dbetagen(y,4,1.2,min=0,max=40),xlim=c(0,40)) The area between the density curve and the x axis does not seem to measure 1!!! --

Re: [R] Status of the "bs" Package

Perhaps there's a problem with the function rbs, that generates a random sample from the Birnbaum-Saunders distribution. The rgbs function (package gbs) does it better. Look at these code and results: > library(bs) > set.seed(1) > alpha<-0.17 > beta<-130 > x<-rbs(n=1000,alpha,beta) > # sample mea

Re: [R] Status of the "bs" Package

Perhaps the problem stands on the rbs function which generates random samples from the Birnbaum-Saunders distribution: > library(bs) > set.seed(1) > x<-rbs(n=1000,alpha=0.5,beta=1.0) > # sample mean > mean(x) [1] 1.117749 > # expected value > beta*(1+alpha^2/2) [1] 2.125 > # so different! -- Vie

Re: [R] Status of the "bs" Package

Hi, the package bs, version 1.0, is available. Yet, I've gote some problems with it, specifically with the maximum likelihood estimation of the parameters \alpha and \beta of Birnbaum-Saunders distribution. Let the following code run: library(bs) alpha<-1.5 beta<-0.5 n<-100 set.seed(1) x<-rbs(n,al

Dear all, a statistical question: how can I compute exact confidence intervals for the lognormal distribution parameters? I found something only on www.weibull.com www.weibull.com . Does exist a package in R which can compute them? Thanks in advance, KTK -- View this message in context: http://

[R] how to modify a function in a R package calling other (invisible?) functions
