On WXP with R2.6.1, and version 0.5.7 of ggplot2, ggplott threw an
error whose second line stated that:
'variable "stat_q5" of mode "function" was not found'
So I defined stat_q5 with the same function code as q5 above and the
plot appeared.
I have a follow on ggplot2 question for which I have not found the
correct terms for a successful search: how does one change the
background fill for the plots? I really would like something other than
grey backgrounds and they seem to be the default.
