Hi, all! I'm very new to RStudio, but thankfully I've been given the code I need (I just have to rename everything and make sure it runs).
When I create a boxplot using the following line of code, it creates a boxplot including a blank category for the "AgeLet" group.
LengthPlotZ <- ggplot(FDataZ, aes(x=SexLet, y=Length_z, fill=AgeLet)) +
geom_boxplot()
LengthPlotZ

How do I exclude missing values? Any help is appreciated. If you need anymore information to better help, please let me know!
