Hello All,
I am trying to put a math expression into a plot title and at the same time, I want a value in the title to depend on a variable that I set earlier.
Simple Example:
n <- 20 plot(0, 0) title(expression(paste(n[i], " = ", n)))
Obviously, I want "n_i = 20". How can I get that?
Thanks in advance,
