dds <- DESeq(dds). This shows gene_id and gene_name.

Perform differential expression analysis

results <-results(dds) results summary(res)

In the results, the gene_id and gene_name are missing. Can anyone please help fix this?

NOT an experienced R programmer.

Rather than showing code that you ran, show the actual results from your R session (e.g., run the code and then copy/paste the results here.

Also, please pay attention to what's in the question box when you first start a post. There are places there for you to paste the code that will cause it to be formatted in a way that makes it easier for people to read your code. The idea is for you to use that rather than just deleting it.
