Just put it in quotes.  In fact, I think italic("attraction") looks 
better than italic(attraction), so you may want to do this more generally.

For example,

plot(1, main=expression(paste(italic("attraction function: "), "slope")))

[R] How to use a reserved word in italics in an expression

Dear R-helpers,

 > label2 <- expression(paste(italic(attraction function:), 'slope'))
Error: unexpected 'function' in "label2 <-  
expression(paste(italic(attraction function"

How do I tell R that in this case I don't want 'function' to be  
treated as a reserved word but as a string in italics?
