[R-pkg-devel] Using ggplot2 within another package

I'm trying to help clean up an R package for someone else to submit to 
CRAN. He has used ggplot2 to implement a plotting function for the kinds 
of things that his packages generates. His plotting routine basically 
looks like (after changing names to protect the innocent):

myPlot <- fucntion(myData, ...) {
    # get ready
    ggplot(myData, aes(x = myX, y = myY)) +
       # add my decorations

Of course, "R CMD check --as-cran" complains that there is no global 
binding for "myX" or "myY" since they are columns defined in the 
data.frame "myData".

What is the best way to work around this issue?

Of course, dinosaurs like myself might be tempted to suggest just using 
plain old "plot", so I don't need to see those suggestions.

Do I just ignore the usual ggplot conventions and write "myData$myX" 
inside "aes"  in order to appease the CRAN checker? Or is there some 
tidy-er way to solve this problem?
