Double group on x axis with ggplot

I have a similar case where one of my species category (lets assume Gentoo) has only lenght measurements. When I plot I get depth and length labeling to appear under Gentoo but actually there is no depth barplot. How can I tell R Studio to delete the depth barplot for that specific Gentoo species? Thanks in advance

Great tutorial. You can use ggview package to check the right size of graph before saving it. Cheers.
