[R] Question about removing missing data rows in the qplot

[Wang, Zhensheng]

Hi,



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

qplot(Bacteria,log(MIC),data=project2,facets=Gram.Staining~Antibiotics,color=Bacteria,geom='bar',stat='identity',fill=Bacteria,na.rm=TRUE)+coord_flip()



I also enclose my plot.



Thank you!



Wang Zhensheng
