Dear All,

I wonder if R stops support for "makeTxDbFromUCSC" function? I tried many times but keep failing with the error message below:

**> txDB <- makeTxDbFromUCSC(genome = "hg19", tablename = "ensGene")**

**Error in makeTxDbFromUCSC(genome = "hg19", tablename = "ensGene") : 
  could not find function "makeTxDbFromUCSC"**

Any input is appreciated.

Thanks,

Xiao
Did you load the library?

    library(GenomicFeatures)
