Thank to both of you.
I found an interesting document by Uwe Ligges in Rnews December 2002 (Vol
2/3)
The following seems encouraging
x=seq(1,180,by=1)
beta=10
eta=5
plot(x,log(x),type="p",xlab="x",ylab="h(x)",main=substitute("Failure rate "
* eta==myeta * "," * beta ,list(myeta=eta,mybeta=beta)) )
but then it fails :
x=seq(1,180,by=1)
beta=10
eta=5
plot(x,log(x),type="p",xlab="x",ylab="h(x)",main=substitute("Failure rate
from W(" * eta==myeta * "," * beta==mybeta , ")"
,list(myeta=eta,mybeta=beta)) )
Any idea ?
Thank you very much
