Hello,
I still have my problem. I couldn't make Uwe Ligges's example work. I wonder
why :-(
The following doesn't work :
param.list=list(mu1=0,mu2=0,s1=3,s2=2,s3=2,s4=4)
plot(1:8,type="n")
text(8,3,adj=1,labels=substitute("with " * mu ==
bgroup("(",atop(mu1,mu2),")") * "," * Sigma[x] ==
bgroup("(",atop(s1~~s3,s2~~s4),")"),param.list))
But this works :
plot(1:8,type="n")
text(8,3,adj=1,labels=substitute("with " * mu ==
bgroup("(",atop(mu1,mu2),")") * "," * Sigma[x] * "=" *
bgroup("(",atop(s1~~s3,s2~~s4),")"),param.list))
So like in my problem the problem seems to be ==.
Same as in my former mail:
x == y == z
is an invalid expression but you must specify a valid one, even for
plotting. ;-)
Best,
Uwe Ligges
Thank you very much

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

Try this:
plot(x, log(x),
xlab = "x", ylab = "h(x)",
main = bquote(Failure~rate~from~W(eta == .(eta), beta == .(beta)))

Hello,
I have to do a few graphics of the same function and this function is
parametrized by two arguments.
What I would like is to be able to change the value of these two
arguments
without changing the plot command. So as to copy paste.
I tried the following :
x=1:100
eta=10
beta=5
plot(x,h(x),xlab="x",ylab="h(x)",main=substitute( expression(
paste("Failure
rate from",W(eta==myeta,beta==mybeta) ) ) ,list(myeta=eta,mybeta=beta) )
)
But it doesn't work. It's written "expression ( Failure rate from
W(eta=10,)
..." on the plot with eta as a greek letter.
Thank you very much !
