substitute in graphics

[Gustave Lefou]

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 !

Try this:

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