Re: [R] Compiling Rgraphiz on Windows 7 64bit with R-2.13.0
lol, I'm having problems with texi2dvi as well...
The Rdlatex file says:
Hmm ... looks like a package
Error in texi2dvi("Rd2.tex", pdf = (out_ext == "pdf"), quiet = FALSE, :
pdflatex is not available
Error in running tools::texi2dvi
You may want to clean up by 'rm -rf
C:/DOCUME~1/AB/IMPOST~1/Temp/RtmpOJ8zBP/Rd2pdf2ff2d7a'
With the last version of Rtools, R 2.13 and Miktex 2.6 running on Windows
XP.
Thanks in advance for your help
KtK

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.

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,alpha,beta) est1bs(x) The MLE algorithm does not converge. Not only for this pair of values and for this sample...

[R] homals (level numerical, scoremat and catscores...)
Just run this code:
library(homals)
data(sleeping)
sleeping
res <- homals(sleeping[,2:4], level = c(rep("numerical",2),"nominal"),
ndim=1)
plot(sleeping[,2],res$scoremat[,,1][,1],axes=F)
axis(1,sleeping[,2])
abline(h=res$scoremat[,,1][,1])
box()
It looks strange, innit? There is something which does not come out right
among catscores and scoremat... which are the right transformed values?
:working:
