To prevent confusion you might want to use a red dot rather than
a line:
points(1:2, c(mean(a), mean(b)), col = red)
and perhaps label it since its non-standard:
text(1:2, c(mean(a), mean(b)), Mean, pos = 4)

How to add a mean line in the
The problem with a line, I think, would be that the width of the boxes
can vary depending on the number of boxes in the plot, etc. No doubt
it could be done, but you'd probably have to look into the bxp
function to see how the widths are calculated.

And if you really do want a line segment try this:
M - c(mean(a), mean(b))
segments(1:2-0.4, M, 1:2+0.4, M, col = red)
