Subject: [R] Greek character and R

Dear R users.

In a loop, I set the title of my graph with :

        mytitle = expression(paste(delta^13,'C Station ', i)
        title(mytitle)

However, instead of using value of i, it will literally use "i" character.

Any one know the way to concatenate the value of i to the mathematical
expression?

With regards,
Phil
