I am trying to annotate a table of genes with transcript type (TXTYPE) using Homo.sapiens annotation package within Annotation.Dbi . I want to do this so I can select for only rotein coding genes and remove all the RNA encoding and psuedogenes

I m using the following code:

all_genes$TxType <- mapIds(Homo.sapiens,

However in the Tx.type column is just full of n/a's. The code works with GeneName as column. 

Is the problem that only transcripts rather than genes can be annotated with TXTYPE information?
