I am using targetScan package for R. The function mget for targetscan.Hs.egTARGETSFULL gives an error when it stumbles upon an entrez gene id (a key) in which there is no value giving the error e.g. Error in .checkKeys(value, Lkeys(x), x@ifnotfound) : value for "101930100" not found. I want the function to skip the ones in which there is no corresponding value and find the values for other entrez gene ids. Do you guys know a way around this ? Thanks in advance for your time.
