Parsing greek letters in facet_wrap titles

[hefin....@gmail.com]

Hi all, please consider the data and plot generated by this code:

library(ggplot2)

df <- data.frame(x = rnorm(100, 100, 20), y = rnorm(100, 100, 20),
                 group = rep(c("IFNa", "IFNb"), each = 50))

ggplot(data = df, aes(x, y)) + facet_wrap(~group) + geom_point()

Instead of IFNa and IFNb, I would like the titles to read IFNα and IFNβ. I have tried using:

+ facet_wrap(~group, labeller = label_parsed)

but I'm not sure what format my group labels should be in. I tried the format:

paste("IFN","alpha")

but this didn't work. Can anyone please suggest a way to do this and combine standard latin text and greek letters in my facet_wrap titles?

Thank you
Hefin

Hefin, 

I think try solutions here:

http://docs.ggplot2.org/dev/labellers.html

The parsed labels you have to create yourself I think.
