Dear BioConductor Community I couldn't find an answer to the following simple question anywhere: I have a list of 300some HGNC IDs, and I would like to retrieve their transcript and protein lengths. I cannot find any argument in the biomaRt BioConductor functions to do that or in the Ensembl biomart on the website either Help me please!!!
