I was trying to do gene set enrichment analysis on genes using fgsea

library(msigdbr)
library(fgsea)

geneSets <- msigdbr(species = "Mus musculus", category = "C5", subcategory = "BP")
geneSets$gene_symbol <- toupper(geneSets$gene_symbol)
geneSets <- geneSets[geneSets$gene_symbol %in% names(trade_obj_condition),]
m_list <- geneSets %>% split(x = .$gene_symbol, f = .$gs_name)
stats <- assocRes$waldStat_lineage1_conditionWT
names(stats) <- rownames(assocRes)
eaRes <- fgsea(pathways = m_list, stats = stats, nperm = 5e4, minSize = 10)

but I get the following error:

error in preparePathwaysAndStats(pathways, stats, minSize, maxSize, gseaParam,  : 
  Not all stats values are finite numbers

Any idea to solve this?

Not all stats values are finite numbers

What is unclear? I see NAs in your data, these are not finite, and that's what the error tells you. What is the tool that returns the ranking metric? You need to rank by something that is continuous and has no missing or infinite values.

ok, I know the problem but I was trying to understand if make sense to remove directly genes with NA values

The question is why there are NAs.

What is the tool that returns the ranking metric?
