Include gene ontology codes in the plots generated using the enrochplot package

Question

[Gene_MMP8]

I was trying to plot the gene ontology (BP; CC; MF) terms for a set of genes as shown in the figure below. The codes used to generate the plot is
go <- enrichGO(de, OrgDb = "org.Hs.eg.db", ont="all") dotplot(go, split="ONTOLOGY") + facet_grid(ONTOLOGY~., scale="free")

However, instead of the gene ontology names (such as organelle fission), I want to plot the GO codes (GO:0048285) on the y axis. Is there any way to do that? Also, my second question is regarding the x axis. What does "Gene ratio" represent here? Is it the number of genes enriched for that particular term divided by the total number of genes?

Hi,

if I read the source code correctly then the Description column is unfortunately harcoded.

The easiert workaround would simply be to replace this column by the one you want.

library(clusterProfiler)
library(DOSE)

#/ Some example data:
data(geneList)
de <- names(geneList)[1:100]
go <- enrichGO(de, OrgDb = "org.Hs.eg.db", ont = "all")

#/ Make a copy to keep the original and replace description with ID:
go2 <- go
go2@result$Description <- go2@result$ID
dotplot(go2)

You could of course also extract the results and make a custom plot.

For the gene ratio question maybe see ClusterProfiler : What is GeneRatio and BgRatio? but this is most likely explained somewhere in the vignette / manual.
