What are "meanlog" and "sdlog"?  My telepathic capacity is severely 
limited, and R's mind_read() function is still under development.

Any help is highly appreciated. dev.new() ; qqPlot(serving,

There is no "qqPlot()" function in the automatically loaded packages in 
R.  There is a qqplot() function but it appears to have a different 
argument list.

So where (what package) does qqPlot() come from?

And while you're at it, how about a *reproducible* example?

When you are seeking help, have the decency to express yourself in a
