You seem really, really confused (and you offer very little in the way  
of context to support debugging efforts). You are referring to ggplot  
functions. As far as I know there is no connection between the Hmisc  
and ggplot (or ggplot2) packages. Al things change, I know, but Frank  
just completed switching over to Lattice a couple of years ago.
