I have a problem that I am not able to solve at the moment. I want to use greek letters in my plot titles. I can make:

ggtitle("My title")

And I know how to print an alpha.

ggtitle(bquote(alpha))

But how it is possible to combine these two in the caption "My title for α"?

Thank you for your help!

Michael

Re duplicate tag - it really doesn't matter how you intend to use the expression, the solution is the same – Richard Telford Oct 02 '18 at 17:21

Did you try `ggtitle(expression("My title for "~alpha))`. That's basically what the duplicate says. – MrFlick Oct 02 '18 at 18:58
ggtitle("My Caption for " * alpha ~ "= 1/2") – Mischu Oct 05 '18 at 18:04
