Hello, I have a file of my differential expression output consisting of gene symbols that I want to convert to ENTREZ IDs. Is there a way to convert it in the original file and discard ones that don't convert along with their corresponding data? E.g. the columns are gene name, basemean count, adjusted p-value and I want to convert all of the gene name column and discard any rows with improper conversions. I tried the org.mm.eg.db and the AnnotationDbi packages but I keep getting errors where it says the package isn't found and I'm uncertain how to convert it using my file instead of from a list with all the gene symbols as strings.
