I am working with r studio trying to make a bar graph to show if there is a correlation between $2$ of my variables. My code works but my graph has NA values on it$.$ How can I remove the NA values? The data name is Final and my variables are Drink and Gender.

My code:

myplot ggplot$($Final$,$ aes$($Drink$,$ group $=$ Gender$))+$

geom$\_$bar$($aes$($y $=..$prop.., fill $=$ factor$(..$x$..)),$ stat$=$"count"$)+$

scale$\_$y$\_$continuous$($labels$=$scales::percent$)+$

ylab$("$Percentage$")+$

facet$\_$grid$($~Gender$)$
