Say v is a VennDiagram:

v$labels <- rep("", length(v$labels)

v$labels <- c("A", "", "C") ## don't print label for B

text(.5, .5, "my text here") will print "my text here" right in the
middle of the graph. Adjusting the coordinates will adjust the
location. You can use v$centers and v$diameters to position text
relative to the center of the circles, but I'm not sure how to
automatically find the unions. You could do it by trial and error.

v$colors <- c(.1, .5, .9)

see ?text
