Bar Plot error

[SynatKeam]

Dear Professor,

Hope you are doing great. I am using ClusterProfiler for GSEA and been trying with MSigDB. Follow are my codes.

MSigDb analysis

library(msigdbr)
msigdbr_show_species()

Step 1

C3_t2g <- msigdbr(species = "Mus musculus", category = "C7") %>%
dplyr::select(gs_name, entrez_gene)

head(C3_t2g)

Step 2

em2 <- GSEA(geneList, TERM2GENE = C3_t2g)
head(em2)

Visualization

dotplot(em2)
barplot(em2, showCategory=20)

Once I visualized with dot plot it worked okay, but barplot did not work as I kept getting the following error.

Error in barplot.default(em2, showCategory = 20) :
'height' must be a vector or a matrix

it is not a normal dataframe and I have been trying to fix it, but not solve it yet. Appreciate if you could give me a guide to proceed with barplot with my case. I am looking forward to hearing from you soon.

Kind Regards,

Synat

I have just realized that the author did not implement barplot for GSEA.

Thanks,
