This should be very easy. (I'm not reviewing your code since it is obviously
not reproducible yet. Presumably you would want to use tail( vectname, 1) to
get the last point.)
To plot a large red "point" (actually a circle) at 0 in the first "column" of
the first example on the ?boxplot page, you would issue:
points(1, 0, cex=5, col="red")
