5 of us are down here in the room. Hermitage Room, Lower Level of Building 2. Is the presenter going to be late?

Security should have directed you to the other side of the building, we're in the Jackson room
Doug- Great question! I have done some work with greek symbol inclusion before (betas etc.), but have not done full on mathematical equations. That said, I was able to google some interesting help pages that may be of interest.
First from the horses mouth: https://github.com/hadley/ggplot2/wiki/Plotmath
Some more complicated equations (w/ sub/superscripts):http://stackoverflow.com/questions/15125628/putting-mathematical-symbols-and-subscripts-mixed-with-regular-letters-in-r-ggpl
I will try to work these in if possible.
Great, thanks for the resources and for trying to include this issue into tonight's meeting!
R, and ggplot2 in particular, seems to follow a new catch phrase I've come up with (but hardly unique, I'm sure):
Modern software: Making the hard things easy and making the easy things nearly impossible! :)

Hi Laura Wiley! If you can, I'd love to hear a bit about making "plotmath" behave within the ggplot2 context. I often need to add mathematical formulas, along with text assocatied with it, into my graphs, and plotmath constantly does not like my expressions and definitely will not tolerate anything other than a valid R expression. So, when I need to add something like "if t <= k: h'(t) = (b - c ) / N; if t> k: h'(t) = (k - c) / N", it chokes horribly and my only workaround has been to add annotations in a piecmeal fashion (which is nightmare-ish if one needs to alter the axis scales across graphs --- I presently have to manually readjust for each unique scale). Thanks!
