Hi My name is Rocky and I am trying to use the org.Dm.eg.db library. When I am using the org.Dm.egFLYBASE2EG[fb_ids] it is stopping at a point where it cannot find any value for a given ID such as the following: Error in .checkKeys(value, Rkeys(x), x@ifnotfound) : value for "FBgn0004461" not found Then the whole thing stops. I cannot retrieve any information on the values that has been found until this ID was reached. Can anyone help in retrieving all the IDs without stopping at a certain ID or if the value for the ID not found just generate an NA for that ID but do not stop....
