[R] embedding expression into title in R plot

Suppose I've specified that the xlab for a plot is
In other words, I want the axis label to be bold, italic 'species (N1)'
Now, I want the title for the plot to be have this label embedded in the
Say, 'This is the plot for Species (N1)'.
For a variety of reasons, I've set this up so that the xlab is a global
parameter (basically, because the labels are set in a function which
when called, generates various plots):
x_label <<- expression(bold(species~(italic(N1))))
So, in the title, I've tried
title(main=paste("This is the plot for ",x_label,"nullcline", sep=" "));
but what this does is generate something like
'This is the plot for bold(species~(italic(N1)))'
In other words, it pastes the text of the expression into the title, but
not what the expression 'evaluates' to.
Is there any way around this?
Thanks in advance...
