Hi,

Could anyone please help me how to put one more categorical variable in ggplot2 command while using facet_wrap. Like I also have one more variable geographic_region along with Compartment and Season.

ggplot(Afribiota_phylum, aes(x = Sample, y = Abundance, fill = Phylum)) +
facet_wrap(~Compartment + Season, scales = "free_x", ncol = 6)

I will be thankful for your help.

Many thanks,

You are in the wrong place. This site is for support for Bioconductor packages, and ggplot2 is not Bioconductor. You might try stackoverflow or biostars or just a well crafted google search
