[Rd] CRAN and ggplot2 geom and stat extensions

[Frank Harrell]

I am thinking about adding several geom and stat extensions to ggplot2 
in the Hmisc package.  To do this requires using non-exported ggplot2 
functions as discussed in 
http://stackoverflow.com/questions/18108406/creating-a-custom-stat-object-in-ggplot2

If I use the needed ggplot2::: notation the package will no longer pass 
CRAN checks.  Does anyone know of a solution?  I'm assuming that Hadley 
doesn't want to export these functions or he would have done so a long 
time ago because of the number of users who have asked questions related 
to this.
