I've a question about the qplot. I use facets=Antibiotics~Gram.Stainng to draw 6 plots in a panel. Now the problem is within each 'Gram.Staining' categorical level there are some antibiotics does not have value (in my case is log(MIU)). Because some antibiotics are positive gram staining and some are negative.

So my question is how to remove these missing value rows in the plot?

My code is


I also enclose my plot.

Thank you!
